85-905 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1050nm

The 85-905 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow wavelength transmission range. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 50 mm and a thickness of 3.5 mm, making it suitable for a wide range of applications.

The filter is constructed from UVFS Mal-1965 material, a common choice for its excellent optical properties. It has a cut-on wavelength of 1025 nm and a cut-off wavelength of 1075 nm, with a central wavelength (CWL) of 1050 nm. This precise wavelength control ensures that only the desired light frequencies are transmitted, reducing noise and improving signal clarity.

The 85-905 filter is hard coated on both the front and back surfaces with EDM 85-881 coating. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time. The filter's thin lens shape further contributes to its versatility, allowing it to be easily integrated into various optical systems.
