Offner Spectrometers

Offner Spectrometers :

Welch Mechanical Designs has designed and built several Offner-based spectrometers. Some of these designs have developed into production runs. We manufacture these spectrometers in a variety of housing types to meet customer requirements.

An Offner spectrometer brings light into the instrument through a slit with typical dimensions of 10 mm x 10 microns, reflects it off a concave primary mirror to a convex diffractive grating, then onto a concave secondary mirror and finally onto the Focal Plane Array.

All WMD spectrometer designs minimize degrees of freedom for alignment to minimize alignment time and ensure long-term optical stability. Our spectrometer systems have deployed in rugged environments such as aircraft and spacecraft and retained their optical performance.

WMD is an industry leader in custom spectrometer design and manufacture. Also, we manufacture several types of diffraction gratings. Please contact us for more information or to discuss your spectrometer needs.
