Worldwide standard for optical metrology

We develop and produce the widest range of optical measurement and manufacturing systems. In this way we enable the development, quality control and production of lenses, lens systems and camera modules.

In the field of optical measurement, we create standards instead of just fulfilling them.

Automatic Alignment Telescope

The D-275-AAT-WW Automatic Autocollimating Alignment Telescope focuses from 40 cm to infinity, to align and measure the location and angular orientation of any number of targets along its optical axis.

  • Only fully automated telescope for alignment and/or measurement of 5-axis of components in optical beam paths and subassemblies
  • Since the mechanical axis of the tube and the optical axis of the instrument are parallel within 1 arc second, the instrument is easily adaptable to mounts, jigs, stages, and setups using a dial indicator.
  • A reflective surface may be established normal to the optical axis by utilizing the autocollimating feature. The D-275-AAT-WW provides the flexibility to align most complex optical assemblies and beam paths.
  • Calibration certified & traceable to NIST standards
  • Remotely controllable using TCP/IP
