64-514 50.8 x 50.8 mm SCHOTT RG645 Red Longpass Color Glass Filter 645nm
The 64-514 is a 50.8 x 50.8 mm SCHOTT RG645 Red Longpass Color Glass Filter, designed to transmit light at wavelengths above 645nm while blocking shorter wavelengths. This filter, sourced from Edmund Optics, is a crucial component for various optical applications that require longpass filtration.
The filter is made of SCHOTT glass, a renowned material for its excellent optical properties and durability. It features a rectangular shape, with a width and height of 50.8mm each, providing a substantial area for light transmission. The filter has a thickness of 3mm, ensuring robustness and stability in its placement within optical systems.
The 64-514 filter is designed with a cut-on wavelength of 645nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than 645nm. This specificity in wavelength selection makes it ideal for applications that require the isolation of red light.
The filter is coated on both the front and back with EDM 64-512, a coating that enhances its longpass filtering capabilities. The coating also ensures the filter's longevity and resistance to environmental factors, contributing to its reliability in various applications.
The filter is shaped as a thin lens, allowing for easy integration into optical systems. It is currently in stock and available for purchase through the provided weblink.
