The Trioptics TriAngle ®

The TriAngle ® electronic autocollimators are non-contact optical test tools for the high-precision measurement of angular displacements of specular reflectiveTriAngle1 surfaces and the accurate angular alignment of optical or mechanical parts. TriAngle® autocollimators are available in five application specific variants:

TriAngle® the most versatile electronic autocollimator for standard applications

TriAngle® UltraSpec enhanced sensor technology for highest resolution and ultra precise measurement results

TriAngle® 3D First Autocollimator measuring angles along three axes: PITCH, YAW AND ROLL ANGLES

TriAngle® HiSpeed for high speed angular measurements

TriAngle® LASER for small or low-reflectivity samples or long distance measurements

NIR Autocollimator TriAngle for characterisation of IR components

TriAngle® autocollimators have a versatile modular design which allows the fitting of a large 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 digital camera interface enables the use of a notebook or desktop PC, or a mobile touch-screen display unit for measurements in the field. The comprehensive OptiAngle® software records, analyzes, stores and reports the measurement results for later reference. A comprehensive set of predefined measurement programs cover all standard applications. It includes

  • Absolute and relative angle measurements of mirror surfaces
  • Absolute and relative angle measurements of collimated sources
  • Wedge angle measurement
  • 90° prism errors
  • 45° prism errorsTriAngle Mobile
  • Wobble (run-out) measurement of rotating samples
  • Straightness measurement
  • Flatness measurement
  • Squareness measurement

User defined measurement procedures can be added into the standard software by a plug-in mechanism. In addition there is an open programming interface for the integration of the TriAngle® measurement functions into other applications. Upon request, TRIOPTICS offers customized TriAngle® instruments, as for example

TriAngle UltraSpec

  • Increased measurement ranges
  • Larger apertures
  • Vacuum compatibility
  • Focusing objectives
  • Customized illumination
  • Customized sensor technology
