Focal Ration Degradation (FRD) is a change in light angular distribution caused by fiber optics. FRD is important to fiber-fed, spectroscopic astronomical systems because it can cause loss of signal, degradation in spectral resolution, or increased c

Extremely low temperatures may damage the optical components assembled inside of an astronomical instrument due to the crack in the resin or glue used to attach lenses and mirrors. The environment, very cold and dry, in most of the astronomical obser

The use of Volume Phase Holographic (VPH) gratings in astronomy is increasing worldwide due to its high efficiency, flexibility in manufacturing and lower costs. For example 3 of 4 SOAR Telescope spectrographs are based on VPH gratings. Following the
