Request InfoDeposition Sciences Inc. (DSI)Deposition Sciences Inc. has introduced IR narrow-bandpass filters for industrial, medical and biological sciences instrumentation. They offer high spectral performance with accurate center-wavelength placement and good temperature stability, rendering them suitable for spectroscopic applications such as gas sensing. The IR spectral range enables the user to detect a particular gas and to identify the concentration levels of gases such as CO2, CH4 and HOx. The IR narrow-bandpass filters allow discretization of the spectra through a gas sample at multiple detection wavelengths inside and/or...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2022 IssueOptical Spectrum AnalyzersThe AQ6375E and AQ6376E optical spectrum analyzers from Yokogawa Europe BV, Test & Measurement combine short- and mid-wavelength IR with extreme optical precision to aid in the development of...Photonics.com 5/23/2022Near-eye Display Measurement SystemThe Rx-series prescription near-eye display measurement system from Gamma Scientific Inc. is specifically designed to measure optical clarity and image quality for optical corrections such as...BioPhotonics May/Jun 2023 IssueBandpass FiltersThe ADVANTECH™ hard coat bandpass filters from Andover Corp. offer steep slopes, high light transmission, durability, and long life for demanding applications.
