The 66-107 is a 50 mm diameter color glass filter, specifically designed for longpass applications at 850nm. This filter is sourced from the renowned optical vendor, Edmund Optics, and boasts a catalog number of 66-107. The filter's primary function is to block light below the specified wavelength, allowing only light above 850nm to pass through.
This filter is characterized by its circular shape and thin lens design, making it a versatile choice for various optical setups. The geometry of the filter includes a diameter of 50mm and a thickness of 3mm, providing a robust structure while maintaining a compact profile.
The 66-107 filter features a unique coating on both the front and back surfaces, identified as EDM 54-664. This coating enhances the filter's performance, ensuring efficient light transmission and blocking capabilities.
The filter's physical data includes a cut-on wavelength of 850nm and a cut-off wavelength of 0nm. This means that the filter begins to transmit light at 850nm and does not block any wavelengths below this point.
