Spectrograph helps Hubble see deep into space

McPherson is providing equipment for the Cosmic Origin Spectrograph, which will be deployed to help the Hubble Space telescope to observe faint ultraviolet targets – both in and out of this galaxy.

COS is currently undergoing extensive pre-flight testing at deep-UV wavelengths normally only accessible in space. A team from the University of Colorado Centre for Astrophysics and Space Astronomy contracted McPherson to provide a system for spectral testing and calibration on the COS optical train.

The instrumentation includes a vacuum monochromator and beam delivery optics to function at wavelengths from 115nm to 300nm. McPherson previously helped to calibrate space flight systems for the Chandra X-ray Observatory and the Space Telescope Imaging Spectrograph (STIS).
