TriAngle
Electronic Autocollimator
Electronic autocollimator for precise optical angle measurement
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. The modular design, the large variety of products and the extensive accessories allow the use of the TriAngle autocollimators for various angle measurement applications in optics manufacturing as well as in mechanical engineering.
