内螺纹光学测试装置(见图1右上角)可做为万能工具显微镜上的附件。该装置系用光学方法非接触的测量螺纹环规的内径、外径、半角、螺距和中径。还可以观察内螺纹轴向断面的直线性。它的测量范围是:螺距在3毫米以下、直径在32~120毫米的螺纹环规。测量精度为:半角为±6,螺距为0.0

The internal thread optical test set (see the upper right corner of Figure 1) can be used as an accessory to the universal tool microscope. The device is non-contact optical method to measure the inner ring diameter, outer diameter, half-angle, pitch and diameter. You can also observe the linearity of the axial section of the female thread. Its measuring range is: thread pitch below 3 mm, diameter of 32 to 120 mm thread ring gauge. Measurement accuracy: ± 6 half-width, pitch is 0.0
