86-063 12.5 mm Dia. High Performance Longpass Filter with 875nm Cut-On
The 86-063 is a high-performance longpass filter, boasting a 12.5 mm diameter and a thickness of 2 mm. This filter is designed and manufactured by Edmund Optics, a trusted name in the optical industry, and is available for purchase through their official website. The catalog number for this particular filter is 86-063.
This filter is designed to allow light with wavelengths greater than or equal to 875 nm to pass through while blocking shorter wavelengths. This is referred to as the cut-on wavelength, which is a critical specification for any longpass filter. The cut-off wavelength, on the other hand, is 0 nm, indicating that no light below the cut-on wavelength can pass through.
The 86-063 filter features a circular base shape and is made from UVFS Mal-1965, a material known for its optical properties. The filter is coated on both the front and back surfaces with EDM 86-063, a coating that enhances its performance and durability.
The filter's geometry includes a diameter of 12.5 mm and a thickness of 2 mm, making it suitable for a wide range of optical applications. The shape of the filter is thin lens, which is a common design for filters due to its minimal impact on the overall optical path.
