Infinity Focus Autocollimators
Electronic Autocollimator LA100-E
A non-contact optical test tool for the high-precision measurement over a wide input aperture measuring angular displacements as well as angular orientation of single or multiple collimated laser sources.
The large aperture enables parallel testing of multiple mirrors or multiple laser sources that could be fitted within the 100 mm aperture.
- High resolution of down to 0.01 arc sec or 0.05 µrad, with clear aperture exceeding 100 mm.
- Built-in computer controlled laser pointer for easy alignment.
- Built-in Pan & Tilt adjusting mechanics.
- Hybrid autocollimator fusing together alignment & beam analysis.
Newly introduced IR versions featuring 1060 nm wavelength, with USB 3.0 interface, offering unique IR compatible Autocollimators.
