Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] Optical glass right-angle angle testing device of the present invention such as figure 1 As shown, it is mainly composed of base, movable support 6, digital dial gauge 5, sample stage 11, and right-angle standard block five parts.
[0025] The height of the left leg 1 of the base is 2mm higher than the height of the highest point of the sample table 11, and the higher part is used as a baffle 8; the front of the left leg 1 has a scale 4 with a division value of 1mm, and a movable support 6 on the side. There is a toothed strip in the middle of the assembly strip.
[0026] Roller wheel 2, reading pointer 3, positioning circular hole 7 are arranged on movable support 6. The roller 2 is located at the bottom of the movable support 6 and can rotate 360°. The middle part of the roller 2 has tooth patterns matching the toothed strips. The digital di...

The name of the present invention is a glass sample right-angle test device and its test method, which is mainly used for the angle detection of right-angle samples used in optical glass refractive index testing, and is applicable to both polished and finely ground samples. It has the characteristics of simple, fast and accurate determination of the angle deviation value of a right-angle sample. The present invention mainly solves the problem that the current method for testing the angle of a sample of the refractive index has large human factors and inaccurate test determination. Its main features are: the device consists of five parts: a base, a movable support, a digital dial indicator, a sample table, and a right-angle standard block. The movable support can move up and down, and the height can be adjusted according to the side length of the sample to be tested. Through the reading of the digital display dial gauge, it is simple and accurate to measure the angle deviation value of the sample. The sample stage can move back and forth in two vertical directions on the horizontal plane to realize the angle test of different positions of the sample.
