High precision and easy measurement of the apex angle of the test prism.
This device is based on an autocollimator, which installs the test prism on a high-precision air-bearing rotation stage. It reads the imaging of surface reflections using a high-sensitivity CCD camera, allowing for high-precision measurement of the prism apex angle. Therefore, it can measure small samples (1mm²) that could not be measured before due to weak rear reflections in transmission methods, without any issues. The autocorrelation image incorporates an image processing analysis device, so no special expertise is required for operation. The angle resolution of the autocollimator is 0.01 seconds, and the measurement accuracy of the top model, PM300HR, is the world's highest precision at 0.2 seconds. The software automatically performs reference surface alignment, apex angle measurement, and tilt error (deviation angle) analysis. It is ideal for evaluating triangular prisms, wedge prisms, pentaprisms, polygon mirrors, rutile crystal wedges, and more. Furthermore, all models comply with the German National Metrology Institute (PTB) to establish traceability, and the high-precision rotary encoder achieves this measurement accuracy through proprietary calibration control.
