The TriAngle Series.
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 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.
Traditionally, autocollimators are limited to a very small measurement range of about 1° or less. Their strength is to measure small angular changes very accurately. In contrast the TriAngle VLF autocollimator has been designed for applications requiring a large measuring range without compromising the measurement accuracy and resolution.
