Laboratories, observatories, and manufacturers throughout the world are using precision Davidson optics and instruments for metrology, aerospace, astronomical, military, medical, life science, industrial, automotive and commercial applications.


In 2017, Davidson Optronics, Inc. was merged into its parent company Trioptics, Inc. ( which continues to produce highest-quality products under the Davidson Optronics brand and supports Davidson Optronics customers with calibration and repair services.

D-275 AAT – Automatic Alignment Telescope


The Davidson D-275 Automatic Autocollimating Alignment Telescope (AAT) 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 provides the flexibility to align most complex optical assemblies and beam paths.
  • Calibration certified & traceable to NIST standards
  • Remotely controllable using TCP/IP
