The 615FDL50 is a high-quality Dichroic Filter, measuring 50 x 50 mm, manufactured by Knight Optical. This Longpass filter has a cut-on wavelength of 615nm, making it ideal for applications where light of a longer wavelength needs to be isolated or transmitted. The filter is designed to reflect wavelengths shorter than the cut-on point and transmit wavelengths longer than it.
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 durability and stability. The rectangular shape, often preferred for its ease of integration into optical systems, is another advantage of this filter.
The coating on both the front and back surfaces of the filter is 'kni 615fdl-0', a proprietary coating by Knight Optical. This coating enhances the filter's performance, ensuring a sharp cut-off at the specified wavelength. The filter's thin lens shape allows for easy integration into various optical systems.
The 615FDL50 is currently in stock and available for immediate purchase from Knight Optical's website. With its high-quality materials, precise manufacturing, and excellent performance, this filter is a reliable choice for various optical applications.
