We design and build scientific instrumentatioN



Since the late 1960’s we have been involved with scientific instrumentation for astronomy.  We have instruments at the PS1 and PS2 Telescopes, UH 88″ telescope, NASA Infrared Telescope Facility, Gemini North Observatory, Subaru Telescope, AEOS Telescope Facility and the Mees Solar Observatory.  We are fortunate to be able to contribute to science by building and supporting astronomical instrumentation.

We are a full service provider for scientific instrumentation offering:

Design and design consulting
Testing and troubleshooting

Assembly and Testing

Key Benefits

All warm and cold testing is done “in house”. The Instrument Technicians work together with Electronic Technicians and Systems Programmers to troubleshoot problems encountered during a testing session.  Modifications or repairs can be done with minimal down time to the mechanism or assembly.

Dichroic Assembly for the IRTF

UH 88″ UHWFI Filter Wheel and Housing 



  • Clean Assembly Rooms for optical installation and mechanical assembly.
  • Cold testing can be conducted in one of our liquid-cryogen-cooled test dewars. This has the advantage of a relatively short cycle time.
  • Cold testing can also be performed within the instrument itself. This has the advantage of being able to test large mechanisms at controlled temperatures.
  • Leak detection with our Varian 979 Helium Leak Detector at our Hilo facility.
