Infrared Bandpass Filter, Φ10mm, FWHM: 0.32±0.03μm, CWL: 7.36±0.06μm, United Optical Technology Co., Ltd (CAT#: STEM-OP-4319-YJL)

Infrared Bandpass Filter, Φ10mm, FWHM: 0.32±0.03μm, CWL: 7.36±0.06μm, model 200050, is manufactured by United Optical Technology Co., Ltd.
Mid- and far-infrared filters can transmit light with a specific absorption spectrum of a substance while blocking other unnecessary interfering light, so they are widely used in environmental monitoring, safety detection, FLIR, etc. For example: detection of carbon dioxide (CO₂), methane (CH₄), carbon monoxide (CO), ammonia (NH₃), moisture (H₂O), ethanol (CH₃CH₂OH), sulfur dioxide (SO₂), nitrous oxide (N₂O) and other substances.
