The 64-707 is a Longpass Filter, sourced from Edmund Optics, with a 50 mm diameter and a thickness of 5 mm. This filter is designed to transmit light with wavelengths above 588 nm, while blocking light with shorter wavelengths. The cut-on wavelength is set at 900 nm, indicating that it allows the transmission of light at wavelengths equal to or greater than this value.
This filter features a circular shape and is made from UVFS Mal-1965 material. It is coated with EDM 49-034 on both the front and back surfaces, which is a traditional coating type. The shape of the filter is thin lens, which is designed to minimize optical aberrations and distortions.
