66-230 12.5 mm Dia. High Performance Longpass Filter with 950nm Cut-on Wavelength
The 66-230 is a high-performance longpass filter, 12.5 mm in diameter, manufactured by Edmund Optics. This filter is designed for applications requiring precise wavelength selection, with a cut-on wavelength of 950nm. It is made from UVFS material, identified as MAL-1965, ensuring durability and high-quality performance.
The filter features a circular shape and a thin lens design, with a thickness of 2mm. It is coated on both the front and back surfaces with EDM 66-230, a high-performance coating that enhances its optical properties. The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
The 66-230 filter is a longpass filter, a type of optical filter that passes wavelengths longer than a specified cutoff frequency and rejects wavelengths shorter than the cutoff. This makes it ideal for applications where longer wavelengths need to be isolated or emphasized.
