The 64-626 is a Longpass Filter, sourced from Edmund Optics, with a 25 mm diameter and a thickness of 3 mm. This filter is designed for use in optical systems that require the transmission of longer wavelengths while blocking shorter wavelengths. The cut-on wavelength for this filter is 525 nm, meaning it begins to transmit light at this wavelength and beyond.
The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. It features a Thin Lens shape, which is beneficial in applications where space is limited or a flat surface is required.
The front and back of the filter are coated with EDM 64-618, a type of coating that enhances the filter's performance and durability. This coating helps to reduce surface reflections and improve transmission, making it an ideal choice for a wide range of optical applications.
