Laser Autocollimators

Optosigma Laser Autocollimators measure angular deviations by projecting a collimated laser beam onto a reflective target and measuring the displacement of the return beam at the CCD detector. They are the standard tool for flatness, parallelism, squareness, and straightness checking in precision optical and mechanical assemblies.

Measurement principle:
– Collimated 635 nm laser beam projected onto flat reflective target
– Reflected beam returns through objective; deviation shifts return spot on CCD
– Two-dimensional angle measurement: tilt in X and Y simultaneously
– Resolution: 0.01 arcsecond with CCD digital readout

Key specifications:
– Working distance: 0.1 m to over 10 m
– Angular range: plus/minus 1000 arcseconds typical
– Laser: 635 nm class 2 diode; eye-safe
– Output: USB to PC with real-time display and logging software

Applications:
– Optical alignment: checking parallelism of optical elements and mirror normals
– Machine tool calibration: straightness and squareness of stages and spindles
– Surface flatness mapping; goniometer stage calibration
