The Spatial Heterodyne Spectrometer (SHS) combines the high resolution and throughput of conventional interferometers with extreme robustness. The SHS does not require scanning to function at its full resolving power. The SHS can be made monolithic by fusing all of the main optical elements into a single block with no moving parts. SSI specializes in SHS with over 10 years of hands-on experience
