510FDL50 50 x 50 mm Longpass Dichroic Filter 510nm
The 510FDL50 is a high-quality Dichroic Filter, measuring 50 x 50 mm, manufactured by Knight Optical. This filter is designed to transmit light at wavelengths above 510nm, making it ideal for applications that require longpass filtration.
The filter is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold. The filter's geometry includes a thickness of 1.1mm, providing robustness and stability.
The 510FDL50 features a coating of KNI 510FDL-0 on both the front and back surfaces. This coating enhances the filter's performance, ensuring a sharp cut-on at 510nm and minimal transmission below this wavelength.
This filter is rectangular in shape, specifically a Thin Lens shape, which is often used in optical systems due to its minimal thickness and weight. The filter's physical data indicates a cut-on wavelength of 510nm and a cut-off wavelength of 0nm, reflecting its longpass characteristics.
Knight Optical, the vendor, provides a catalog number (510FDL50) for easy identification and ordering. The filter is currently in stock and available for immediate purchase through their website.
