The TriAngle® electronic autocollimators are non-contact optical test tools for the high-precision measurement of angular displacements of specular reflective surfaces and the accurate angular alignment of optical or mechanical parts. TriAngle® autocollimators have a versatile modular design which allows them to be fitted with a wide selection of objective tubes, different sensors, reticles and light sources. With objective tubes of different focal lengths and apertures, the optimum measurement solution regarding angle resolution and measurement range is easily found.

TriAngle® autocollimators are available in six application-specific variants:


The most universal electronic autocollimator.

TriAngle® Laser

The TriAngle® LASER is ideally suited for the measurement of small optical components, surfaces of low reflectivity or long distance measurements.

TriAngle® UltraSpec

The TriAngle® UltraSpec offers high-precision angle measurement systems for extremely high demands on angle resolution and measurement accuracy.

TriAngle® HighSpeed

The TriAngle® HighSpeed is the ideal electronic autocollimator for measurement of vibrations or rapidly moving samples.

TriAngle® Focus

The TriAngle® Focus employs focusing objective tubes for contact-free optical radius measurements.

TriAngle® NIR

The TriAngle NIR electronic autocollimators are commonly used to measure surfaces with highly efficient anti-reflection coating.
