Electronic autocollimator TriAngle® NIR

The TriAngle® NIR electronic autocollimators are based on the standard TriAngle design but employ NIR LED illumination for the reticle. The TriAngle NIR electronic autocollimators are commonly used for applications which require measurement at the design wavelength in the NIR. It is used for measurements on material which only transmit light in the NIR range, such as are used in night vision devices. Another application is the laser beam alignment of lasers that emit light at a wavelength in the NIR spectral range.
