What is the general method for the determination of the microscope of the tool?
1. Right-angle coordinate measurement:
Determination must be made to determine the direction of the object of right-angled coordinates and the direction of movement of the cross-shaped table can be measured. When using right-angle coordinate measurement by the movement of the cross-shaped moving table can be read directly from the value of the right-angle coordinates, if a large tool microscope, the use of aperture right-angle coordinate measurement of the image connected to the observation of the eye can be correctly measured, and in the measurement of the direction of the right-angle coordinates of the object and the cross-shaped moving table of the calibration, the use of the assembled rotary table installed in large tool microscopes is very convenient, as for small tool microscopes, just rotary table attachment can be used. As for the small tool microscope, only the rotary table attachment can be used.
Angle Measurement:
The use of rotary stage or angle observation lens can be measured. Generally speaking, the accuracy of the angle observation lens is better.
Height measurement:
Although the small tool microscope can not measure the height, but if the measuring silver mounted on the upper end of the pillar, and then use the microscope up and down to move the amount of height can be measured. However, due to the depth of focus, pillar inclination and the error between the silver and optical axis, it is quite difficult to measure correctly.
4. Aperture measurement:
Generally the use of angular observation lens determination, but the large tool microscope can use overlapping image observation lens or optical detector, that is, the use of overlapping image lens, so that the generation of the two images overlap, and then in the opposite side is also the same, and so by the amount of movement can be shown by the inner diameter of the hole. If an optical detector is used, it is first mounted on a 3x objective lens, then aligned with the direction of movement of the detector and the table, and then adjust the overlap line in the observation mirror parallel to the crosshairs of the observation lens so that the detector contacts the hole surface. Finally, the Y-axis feed is used to correct the reverse movement of the overlap line, and the X-axis feed is used to make the overlap line clamped to the ten sub-lines of the observation lens, and the X-axis measurement value can be read. The same is true for the hole on the opposite side, so the inside diameter of the hole can be obtained by adding the diameter of the detector to the difference between the readings.
