TriAngle® Electronic Autocollimators

The TriAngle® series electronic autocollimators, designed and manufactured by TRIOPTICS Germany, are based on high-resolution CMOS or PSD detectors combined with collimating objectives of various focal lengths. This design provides a very wide measurement range and multiple levels of accuracy to meet diverse application requirements. Depending on the spectral range, the TriAngle® autocollimators are available in UV, visible, and near-infrared versions, enabling measurements across different wavelengths.

Applications

* Measurement of small angular deflections

* Alignment of optical systems

* Alignment of mechanical structures

* Measurement of tilt angles of collimated optical beams

* Measurement of relative tilt between multiple surfaces

* Wedge angle measurement of optical windows

* Measurement of 45° angle errors in right-angle prisms

* Measurement of 90° angle errors in right-angle prisms

* Measurement of rotary table axis wobble

* Measurement of straightness, perpendicularity, and flatness

Key Features

* Supports both relative and absolute measurement modes

* Captures and locates image positions using an area sensor

* A single autocollimator can simultaneously detect and measure up to 12 reflected images

* One PC can control and measure data from up to 12 autocollimators simultaneously
