87-871 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1575nm
The 87-871 is a Bandpass Filter, specifically designed for use in optical systems where precise wavelength selection is required. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 25 mm and a thickness of 3.5 mm, making it suitable for a wide range of applications.
The filter is made from UVFS Mal-1965 material, a common choice in optical systems due to its excellent transmission characteristics and durability. It is designed to pass wavelengths near 1575 nm, with a Cut-On wavelength of 1550 nm and a Cut-Off wavelength of 1600 nm. This specificity makes it ideal for use in systems where narrowband filtering is necessary.
The 87-871 is hard coated on both the front and back surfaces with EDM 87-858 coating. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time. The filter's shape is described as Thin Lens, indicating its potential use in systems where optical power is required.
