Automatic Focusing Autocollimators
Total Station Autocollimator
- An upgraded device based on our already mature technology for testing and adjusting fully integrated systems including mechanics, optics, and lasers.
- Emerging optomechatronics AR/VR industry has introduced special applications requirement:
- Interalignment and testing of lasers, optics, mechanics and electronic sensors
- Angular accurate optical measurements with resolution of 0.01 arc sec or better.
- Implementing fusion of several wavelengths including NIR into one system.
- Measurements from remote mechanical dimensions.
- Centering & Alignment
- Measurements of multi laser array such as VCSEL in respect with other optical sensors.
- Our Total Station Autocollimator does it all and much more, including projection of virtual objects from user defined distance.
