The 45-070 is a 25.4 mm diameter Color Glass Filter, specifically designed by SCHOTT and distributed by Edmund Optics. This filter is a Longpass filter, which means it allows light of longer wavelengths to pass through while blocking shorter wavelengths. The cut-on wavelength for this filter is 665nm, ensuring that only light with a wavelength of 665nm or longer can pass through.
The filter is made from UVFS Mal-1965 material, a Schott glass type known for its excellent optical properties. It features a circular base shape and a thin lens geometry, making it suitable for a wide range of optical applications. The filter has a thickness of 3mm, providing sufficient durability and stability.
The 45-070 filter is coated with EDM 54-659 on both the front and back surfaces. This coating enhances the filter's performance by reducing reflection and increasing transmission. The coating also provides protection against environmental factors, ensuring the filter maintains its optical properties over time.
