What is measuring microscope
1.1 The measuring microscope is used to accurately measure the length and angle of the workpiece by means of transmission and reflection. It is especially suitable for measuring the linewidth of large-scale magnetic head, precision recording circuit and other parts. It is widely used in measurement rooms, production lines and scientific research departments.
1.2 Main advantages:
in addition to the movement of X and Y coordinates, the workbench can also rotate 360 degrees.Observe with binocular eyepiece.
In addition to transparent and reflective lighting, the lighting system can also be used for oblique lighting. The instrument can be further connected with CCD TV camera to enlarge the contour of the workpiece; It can also be connected to the computer for data processing and other measurements.
How to Use Measuring Microscope
Place the target on the stage.
As with general-purpose optical microscopes, subject the target to transmitted light or reflected light, and then align the edge of the shadow with the reference lines to perform measurement. Use different lighting (such as backlighting and coaxial illumination) depending on the target.
The measured values can then be output as various types data.
Types of measuring microscope
2.1 Optical measuring microscope
The length and angle of the workpiece are accurately measured by means of transmission and reflection. It is mainly used to test the line width of video head, large-scale integrated circuit and other precision parts. It is widely used in measurement rooms, production lines and scientific research departments.
Main advantages: in addition to the movement of X and Y coordinates, the workbench can also rotate 360 degrees. It is an ideal small precision measuring instrument in a fixed place.
2.2 Digital measuring microscope
The utility model relates to a microscope device that converts the physical image seen by the microscope through digital to analog conversion to make it image on the screen of the microscope or on the computer. It is especially suitable for manufacturing, precision parts and inconvenient
Observation and measurement of moving objects. It is widely used in production lines and scientific research departments.
Main advantages: compact and portable, only one computer can intuitively observe micro enlarged images, carry out accurate data measurement, take photos and back up pictures and data; Special light sources (fluorescent and infrared) can also be customized according to customers’ needs for observation in special places. Digital measuring microscope has been widely used in recent years and has become a reliable and practical precision measuring instrument.
3.3 Z-axis non-contact
Based on the measurement principle of split image focus indicator, the non-contact height difference measurement is carried out by means of high-precision optical focus point detection. It can not only aim at the target image, but also observe the surface state of the measuring point and measure the height, depth and height difference. The various lens barrels of the instrument also have many observation functions, such as light and dark field, differential interference, metallography, polarization and so on. Therefore, the extremely fine gap height difference, inclusions, protrusions below micron, fine scratches and metallographic structure were observed.
Major function of measuring microscope
