Request InfoDeposition Sciences Inc. (DSI)One of DSI's newest precision coating products is our Low Temperature Shift IR Bandpass Filters. They are ideal for critical applications that require minimal fluctuation in center wavelength (CWL). Infrared coatings typically experience a shift in spectral placement with changes in temperature. DSI’s Low Temperature Shift IR coatings limit the shift to approximately half the amount of “standard” IR coatings. Filter characteristics, such as bandwidth, center wavelength, slopes, blocking level, and more, can be customized depending upon application requirements.
