84-657 50 mm Dia. Traditional Coated OD 2.0 Shortpass Filter; t=5mm 1250nm
The 84-657 is a Shortpass Filter, part of the extensive catalog offered by Edmund Optics. This filter, with a diameter of 50 mm and a thickness of 5 mm, is designed for use in optical systems that require precise wavelength control.
The Shortpass Filter is a type of optical filter that allows wavelengths below a certain value to pass through while blocking those above it. In this case, the 84-657 has a cut-on wavelength of 0 nm and a cut-off wavelength of 1250 nm. This means it allows wavelengths shorter than 1250 nm to pass through while blocking longer wavelengths.
The filter is made from UVFS Mal-1965, a material specifically designed for optical applications. It features a Thin Lens shape, which is ideal for use in compact optical systems. The front and back of the filter are coated with EDM 84-641, a coating that enhances the filter's performance and durability.
The 84-657 is currently in stock and available for purchase through the Edmund Optics website. For more information, please refer to the provided weblink.
