64-657 50 mm Dia. Traditional Coated OD 2.0 Shortpass Filter; t=5mm 975nm
The 64-657 is a 50 mm diameter Shortpass Filter with a thickness of 5mm, designed for optimal performance at a wavelength of 588nm. This filter, sourced from the reputable vendor Edmund Optics, is a crucial component in various optical systems that require the selective transmission or blocking of specific wavelengths.
The Shortpass Filter is a type of optical filter that allows wavelengths shorter than a specified value to pass through while blocking longer wavelengths. In this case, the 64-657 effectively transmits wavelengths shorter than 975nm, making it ideal for applications that require the separation of infrared and visible light.
The filter is constructed with a Base Shape of Circular and a Material ID of UVFS MAL-1965. It features a Thin Lens shape, which is designed to minimize optical aberrations and ensure high-quality image transmission. The filter's physical data includes a cut-on wavelength of 0nm and a cut-off wavelength of 975nm.
The 64-657 is coated with the EDM 64-650 coating on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The coating also provides protection against environmental factors, ensuring the filter's longevity and reliability.
