Multiband Filter

Our Multiband Filters will optimize your research and work. For example, our OH Suppression Filter is a revolution in Astronomy by allowing for an ideally black sky for near-infrared imaging and low-resolution spectroscopy.

Our Multiband Filters also allow up to ten times more efficiency in gas detection, molecular analysis, and Raman spectroscopy, where they enable the user to observe many wavelengths simultaneously.

Up to 30 lines can be isolated with only one filter and a bandwidth as narrow as 0.2nm. These Filters therefore strongly increase contrast and signal-to-noise ratio by blocking or isolating known spectral features simultaneously.
