What is microscope definition
an instrument with one or more lenses used to help a person to see something very small by making it appear larger, the device used for producing a much larger view of very small objects so that they can be seen clearly.
what is stereo microscopes
stereo microscope chutong is an optical microscope that provides a three-dimensional view of a specimen. stereo microscope parts include separate objective lenses and eyepieces. As a result, you have two separate optical paths for each eye. The slightly different angling views to the left and right eyes produce a three-dimensional visual.

4.2 Fine adjustment knob microscope focusing bracket:Slowly moves the stage up or down to get a more precise and greater detail of the object/specimen.
Fine adjustment knobs are the smaller knobs and are also used to raise and lower the stage but more slowly and in a more controlled manner under higher magnifications.
What Is Fine Adjustment Knob?
The fine adjustment knob is a part of the microscope that is used for focusing finer details of a specimen being viewed. Objectives like low power and high power objectives are used with a fine Adjustment knob for a clearer image in higher resolution.
What Is Coarse Adjustment Knob?
The coarse adjustment knob is a part of the microscope used when focusing specimen. This knob is generally used when viewing specimens with scanner objective (4X).
Other objectives like low power and high power objectives are used with a fine Adjustment knob for a clearer image in higher resolution.

What is coaxial coarse and fine adjustment focus knob
Coarse and Fine Focus Block/Holder focus holder with coaxial coarse and fine focus for high magnification applications, Focusing holders hold the microscope body and contain the mechanism that raises or lowers the body to focus on the specimen.Microscopes don’t have ‘auto focus’, so you need to do the focus manually.
Where are the Coarse and Fine adjustment focus Knob?
The coarse adjustment knob on most microscopes is along the lower middle part of the arm of the microscope as shown in the image below.
The coarse adjustment knob is the bigger of the two knobs and is located closest to the arm of the microscope.
The fine adjustment knob is the smaller of the smaller of the two knobs and is located further away from the arm of the microscope.
Most coarse and fine adjustment knobs are built with coaxial control in line with one another so you can easily switch from using the coarse focus adjustment knob to using the fine focus adjustment knob.
What is difference Between coarse and fine adjustment focus Knob
Coarse adjustment tension konb: using the coarse adjustment knobs, raises and lowers the stage more rapidly. Fine adjustment knobs: the smaller knobs and are also used to raise and lower the stage but more slowly and in a more controlled manner under higher magnifications.
relating to or being a binocular microscope equipped with a lens for photographic recording during direct visual observation in simple words, 2 eyepiece plus 1 lens for photograph
A microscope produces an accurately enlarged image to allow the examiner to see things in a larger scale. It may or may not be capable of enough enlargement for the examiner to view cells. Has an Extra Port for Camera
trinocular microscopes has extra space for attaching the camera. This camera helps to take pictures and videos of specimens during observation. So, it makes it possible to share digital prints.
categary mono/bino trinocular microscopes
There are different ways of categorizing microscopes: by their purpose, by their construction, and by how one observes the specimens.
In terms of viewing options, a microscope can be monocular, binocular, or trinocular, i.e., having one, two, or three eyepieces.
microscope may have one of several purposes. One purpose is to allow a second viewer access to a specimen at the same time as the person who is mainly using the microscope.
This means that an instructor can, for example, look at what a student is seeing to answer a question or to check the accuracy of the student’s observations.
In addition, the instructor can invite a student to share his or her view of an interesting specimen or when modeling how to adjust the focus,
for example. This extends the instructional possibilities from the situation in which one person must not be viewing in order for the other person to have a view.
Another purpose of a trinocular microscope is to allow the use of technology to either preserve the images seen through the microscope by recording them or projecting them. In the first case, a digital camera or video camera could be connected to the third eyepiece, which may actually be designed as a port with this specific purpose. If it is not, there are adapters for some microscopes that can adapt a trinocular eyepiece meant for human viewing to a camera. Projecting an image has several advantages including allowing prolonged study without having to stay bent over the microscope itself, sharing images with others who are present in the room, or even sharing the image through a videochat or other means.
trinocular microscopes essential parts
Stage Plate: This part is usually large enough because it holds the specimen ready for view.
Stereo Head: The stereo head of this microscope holds the eyepieces and prism. It also has extra space for camera attachment. The prism helps to rotate the image to the right side up for a dimensional view.
Stage Clips: This part works alongside the stage plate. It helps to firmly hold the specimen in place to ensure stability during observation.
Eyepieces and Lenses: These parts of the microscope helps to magnify specimens. It also serves to get different resolutions for images.
Focus Knob: The focus knob improves focus on images by raising or lowering the eyepieces. It is different from a binocular microscope, where focusing involves raising and lowering the stage.
Lighting Control: The lighting control parts of a microscope regulate the amount of light that interferes with the device.
microscope stage is the aluminum or iron platform where specimen shown for viewing examination, usually the specimen on a glass slide and be clipped, is raised or lowered for observation under the microscope. Microscope stage will often include stage clips that will hold the slide in place while the stage is being adjusted up and down or side to side.
Simple microscope Stage
Visually the easiest way to identify a simple stage is by the stage clips which are usually spring loaded and just lift and hold a slide in place. If the slide needs to be adjusted it must be manually done by the observer’s fingers pushing the slide up, down, or side to side while still clipped.
Mechanical microscope Stage
The mechanical stage is so named because slide movements are controlled by a mechanical system mounted to the stage. The mechanical stage clamps, instead of clips, onto the slide and movement along the X (side to side) and Y (up and down) axis of the stage is controlled by knobs that can more precisely move the slide into position.
microscope stand designed to support microscope body, Microscope stand with characteristics of large lifting range and flexible operation. During the observation process, it can tilt and change various angles, greatly expanding the working space such as industrial assembly and inspection production lines,microscope stand types: boom stand including/post stand /articulated arm/ pole stand/tack stand / clamp base type stand/single arm/dual arm type.
how to choose a microscope stands
Microscope stands have many options depending on the needs, especially stereo microscope stand, there are several factors to consider before choosing. Stability: microscope stand is used to prop up the microscope body. The stand should be selected according to the size of the microscope mainframe. The stability of the stand determines the stability of the microscope in use, and its various adapters and screws must be tightly locked. Volume size: limited by the working environment and space of the workbench. Workspace and scope: the size of the workspace of the object being observed and the height of the object being observed should be considered. Choice of lighting: some stands are equipped with a light source, but some are not, depending on whether there are conditions to add additional lighting.
1. Install the stand as required.
2. Arrange a reasonable fixed position for the stand.
3. Carefully tighten the microscope mainframe.
4. Arrange the location of the additional light source reasonably, and place the electric wire in a position that does not interfere with the work.
5. Connect the various kinds of peripheral devices, such as cameras, monitors, computers and so on.

eyepiece ocular lens to re-enlarge again the specimen image obtained magnified by objective lens, eyepiece with larger field of view and viewing angle magnification.
Microscope Eyepiece ocular lenses that a person uses to view a specimen. Most dissecting microscopes have two ocular lenses set at a magnification of 10×. However, you can increase the magnification of a stereo microscope simply by upgrading the ocular lenses. through which the real image forms an upright and magnified virtual image.Eyepiece is an integral part of the microscope. It is used to observe the optical system into an image of the visual optics. It is usually a combination of several lenses made with a larger field of view and perspectives magnification. Generally divided into Huygens eyepieces, wide-angle eyepieces, and other flat-field eyepieces. The function is to eliminate aberration, so that the image will be more clear.
icon glassess high eye point eyepiece ocular lens
The high eye point means that the eyes can see the image in the eyepiece even if the eyes are far away from the eyepiece. This kind of eyepiece is not only comfortable to look at, but also especially suitable for people who wear glasses.
WF wide field large field eyepiece ocular lens
Wide-angle eyepieces generally refer to eyepieces with a field of view exceeding 50°. These eyepieces all adopt a special structure and have a wide field of view, also known as wide-field or large-field eyepieces, with a large observation range. Therefore, the price is much higher than that of ordinary eyepieces.
So high eye point wide angle field eyepieces are better.
rubber eyeguard: eyegard can effectively prevent glasses from scratching the eyepiece lenses and protect the eyepieces. This rubber eyecup is foldable and suitable for WF10X, 15X, 20X multiples eyepiece.

fine and coarse focus mount with focusing knob
Coarse vs Fine Adjustment difference between coarse and fine adjustment is the range that they have. The coarse adjustment covers the entire range from minimum to maximum. In contrast, the fine adjustment only covers a fraction of the entire range. The bare minimum range for the fine adjustment is the discrete step increment of the coarse adjustment, in order to cover the entire range. It can also be larger, depending on the designer of the device.
1.Coarse adjustment has steps in large increments while fine adjustment has steps in much smaller increments
2.Coarse adjustment covers the entire range while fine adjustment only covers a fraction of the entire range
Coarse adjustment: Brings the specimen into general focus.
Fine adjustment: Fine tunes the focus and increases the detail of the specimen.
Fine Focus a knob used to fine tune the focus of a specimen in conjunction with the coarse focus. The diameter of the circle of light seen through a microscope. The ability to achieve a clear image, typically achieved by moving either the eyepiece tubes or the stage.
Microscope accessories Microscope structure components includes
01 The three basic, structural components of a compound microscope are the head, base and arm.
Head/Body houses the optical parts in the upper part of the microscope
02 Base of the microscope supports the microscope and houses the illuminator
Arm connects to the base and supports the microscope head. It is also used to carry the microscope.
When carrying a compound microscope always take care to lift it by both the arm and base, simultaneously.
Microscope accessories and spare parts function
There are two optical systems in a compound microscope: Eyepiece Lenses and Objective Lenses:
1.1 Eyepiece or Ocular
is what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available, typically from 5x-30x.
Eyepiece Tube holds the eyepieces in place above the objective lens.
Binocular microscope heads typically incorporate a diopter adjustment ring that allows for the possible inconsistencies of our eyesight in one or both eyes. The monocular (single eye usage) microscope does not need a diopter. Binocular microscopes also swivel (Interpupillary Adjustment) to allow for different distances between the eyes of different individuals.
1.2 Objective Lenses
are the primary optical lenses on a microscope. They range from 4x-100x and typically, include, three, four or five on lens on most microscopes. Objectives can be forward or rear-facing.Nosepiece houses the objectives. The objectives are exposed and are mounted on a rotating turret so that different objectives can be conveniently selected. Standard objectives include 4x, 10x, 40x and 100x although different power objectives are available. 1.3 Coarse and Fine Focus knobs
are used to focus the microscope. Increasingly, they are coaxial knobs – that is to say they are built on the same axis with the fine focus knob on the outside. Coaxial focus knobs are more convenient since the viewer does not have to grope for a different knob. 1.4 Stage
is where the specimen to be viewed is placed. A mechanical stage is used when working at higher magnifications where delicate movements of the specimen slide are required. 1.5 Stage Clips
are used when there is no mechanical stage. The viewer is required to move the slide manually to view different sections of the specimen.this is stand base of microscope accessories.
1.6 Aperture is the hole in the stage through which the base (transmitted) light reaches the stage.
1.7 Illuminator is the light source for a microscope, typically located in the base of the microscope. Most light microscopes use low voltage, halogen bulbs with continuous variable lighting control located within the base.
1.8 Condenser is used to collect and focus the light from the illuminator on to the specimen. It is located under the stage often in conjunction with an iris diaphragm.
Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage. Most high quality microscope include an Abbe condenser with an iris diaphragm. Combined, they control both the focus and quantity of light applied to the specimen.
Condenser Focus Knob moves the condenser up or down to control the lighting focus on the specimen.
