The 66-077 is a 50 mm diameter Longpass Color Glass Filter, manufactured by SCHOTT and distributed by Edmund Optics. This filter has a wavelength of 395nm, designed to transmit light at this wavelength and above, while blocking light at lower wavelengths.
The filter is made of UVFS Mal-1965 material, a Schott glass type known for its excellent optical properties and durability. It features a circular shape, with a thickness of 3mm, making it suitable for a wide range of optical applications.
The 66-077 filter is coated with EDM 54-648 on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.
The physical data of the filter indicates a cut-on wavelength of 395nm, meaning it starts to transmit light at this wavelength. The cut-off wavelength is 0nm, indicating that it transmits all wavelengths above 395nm.
This filter is designed in a Thin Lens shape, which is beneficial for applications that require a compact and lightweight optical design. The filter is currently in stock and available for purchase through the Edmund Optics website.
