DSI has extensive experience designing and manufacturing bandpass coatings for use at wavelengths ranging from the ultraviolet through the long-wave infrared. These include broad bandpass, narrow bandpass and even dual (or multi-wavelength) bandpass designs. DSI bandpass filters are characterized by high in-band transmission, strong out of band blocking and immunity to shifts due to changing humidity. DSI utilizes both evaporative and MicroDyn® sputtering methods for the fabrication of bandpass filters. That enables us to tailor coating performance, cost and durability to meet your particular performance specifications and budget. DSI Bandpass Filter Advantages: -High in-band transmission -Sharp cut-on cut-off slopes -Excellent out-of-band blocking -No wet/dry wavelength shift -Extremely small thermal shift DSI Bandpass Filter Applications: -Laser systems -Spectroscopy and fluorescence imaging -Military imaging, target designation and countermeasures -Digital cinema -Medical imaging
