538FDN25 25 mm Dia. Bandblocking Dichroic Filter 538nm
The 538FDN25 is a high-quality Dichroic Filter, specifically designed for bandblocking applications, available from Knight Optical. This filter boasts a 25 mm diameter, making it suitable for a wide range of optical systems. The filter's thickness is 1.1 mm, providing a balance between durability and ease of integration into optical setups.
The filter is designed to cut on at 628 nm and cut off at 449 nm, effectively blocking light within this range while allowing light at and around the central wavelength of 538 nm to pass through. This makes it ideal for applications where specific wavelengths need to be isolated or blocked.
The 538FDN25 features a coating on both the front and back surfaces, identified as 'kni 538fdn-0'. This coating is specifically designed to enhance the filter's performance in bandblocking applications. The filter's shape is that of a thin lens, further enhancing its versatility in optical systems.
The filter is made from N-BK7 Schott, a widely used optical glass known for its excellent optical properties and durability. This material ensures the filter's reliability and performance in various environments.
