TriAngle® high precision electronic autocollimator systems for ultra-precise angle measurement from Trioptics GmbH have now gone mobile.

TriAngle electronic autocollimator


With a portable, light-weight display unit with large touch-screen interface and a one-cable interface between the TriAngle® Mobile autocollimator and the compact display unit you can be assured maximum flexibility with minimum space requirements for measurement operations at remote measurement locations.

The TriAngle® Mobile measurement system is the best choice whenever the instrument has to be as portable as possible. The following measurement tasks give just a small idea of the utility of the system:
  • Alignment of machinery
  • Proof of straightness and flatness of tables, platforms, rails, linear guides, etc.
  • Measuring the stability or deformation of mechanical or optical constructions
  • Alignment of astronomical systems
  • Alignment of components for the beam control in high energy physics.
  • Assembly and adjustment of optical components like mirrors, prisms, windows, wedges etc.

    If you’d like to receive further information on how the TriAngle® high precision electronic autocollimator systems could help in your research or manufacturing or would like to receive our regular e-Newsletter then please CONTACT US and we'll be in touch.
