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. • http://www.trioptics.com/products/ele...
