85-906 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1100nm
The 85-906 is a Bandpass Filter, specifically designed for applications requiring a narrow passband. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 50 mm and a thickness of 3.5 mm. The filter's primary function is to transmit light within a specific range of wavelengths while blocking other wavelengths, making it ideal for applications requiring precise wavelength selection.
The 85-906 filter has a cut-on wavelength of 1075 nm and a cut-off wavelength of 1125 nm, with a center wavelength (CWL) of 1100 nm. This specificity in wavelength range ensures minimal signal interference and high-fidelity data transmission. The filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties and durability.
The filter's front and back are coated with EDM 85-882, a hard coating that enhances the filter's longevity and resistance to wear and tear. This coating also reduces surface reflections, improving the filter's overall efficiency and performance. The filter's shape is a Thin Lens, further optimizing its light transmission capabilities.
