The 64-627 is a Longpass Filter, sourced from Edmund Optics, with a diameter of 25 mm 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 575 nm, meaning it begins to transmit light at this wavelength and beyond.
The filter is made from UVFS material, identified as Mal-1965, and features a Thin Lens shape. The front and back of the filter are coated with EDM 64-619, a traditional coating that enhances the filter's performance and durability.
