PAT-serial Goniometer is a precision comparation angle testing instrument with dual autocollimator design. It could be used for precision measurement for any dihedral angles, perpendicularity, parallelism, as well as the output beam deviation angle, etc. According to the lightsource used, there are two options: PAT-300(white light) and LPAT-650（Green or Red Laser）.
PAT-300 is with better accuracy(about 1 aresec), and it is good for normal prism testing(size≥3mm). LPAT-650 uses monochrome laser as input lightsource, since the laser inherent good directional and small spot characteristics, it is competent for small size product measurement(size ≥1mm). Both devices include measurement software that can capture images in real time and displays the results automatically. It makes the measurement simple and efficiency
- Output Beam Deviation accuracy for prisms
- Beam combination angle accuracy
- Perpendicularity, Parallelism, etc
