Laser Analyzing Autocollimator-Alignment Sensing

Precise USB3.0 device combining the functionality of autocollimator, alignment telescope with laser beam profiling capability.

The system measures minute angular displacements for various optical setups and can align a laser beam to the optical axis or mechanical axes, as well as laser beam divergence analysis.

The system offers portable, compact and accurate beam alignment solution. Our precision electronic autocollimator has built in adjustment features, such as leveling bubble, adjustment pan tilt knobs enhancing the unprecedented alignment procedures (between the laser, the optical and mechanical axis of the device).
