Infrared Interference Optical Bandpass Filters are used to selectively transmit a portion of the welldefined spectrum while rejecting all unwanted wavelengths. Our IR bandpass filters provide better transmission, steeper cut on and cut off slopes, greater blocking, and increased durability.IR optical thin film coating are ideal for a variety of applications, such as IR Thermal Imaging & Thermal Sensing, IR Thermography, IR light Emitters & Detectors etc, clinical chemistry, or imaging. IR Filter,Shortpass / Longpass Edge Filter Filter,IR Antireflection lens and AR window are typically used in the life science, industrial, or R&D industries.
