The 87-882 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow passband. This filter, with a 50 mm diameter, is sourced from Edmund Optics and features a hard coating on both the front and back surfaces. The coating, identified as EDM 87-856, is designed to enhance durability and overall performance.
The filter's primary function is to allow light transmission within a specific range of wavelengths, while blocking light outside this range. The 87-882 is designed for a central wavelength (CWL) of 1475nm, with a cut-on wavelength of 1450nm and a cut-off wavelength of 1500nm. This precise wavelength selection makes it ideal for applications that require tight control over the spectral content of the light.
The filter has a thickness of 3.5 mm, which contributes to its robustness and stability in optical systems. The circular shape and thin lens design further enhance its compatibility with various optical setups. The 87-882 is currently in stock and available for immediate use.
