550FDN50 50 x 50 mm Bandblocking Dichroic Filter 550nm

The 550FDN50 is a 50 x 50 mm Bandblocking Dichroic Filter, specifically designed to block light in the 470-630nm range while allowing light at the center wavelength (CWL) of 550nm to pass through. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and durability. It has a thickness of 1.1mm, providing sufficient structural integrity while maintaining minimal optical distortion. The rectangular shape, often preferred for its ease of integration into optical systems, is further enhanced by the thin lens shape of the filter.

The 550FDN50 features a dichroic coating on both the front and back surfaces, identified as 'kni 550fdn-0'. This coating is designed to reflect or transmit light depending on the wavelength, making it highly effective in bandblocking applications. The cut-on wavelength is 630nm, and the cut-off wavelength is 470nm, indicating the range of wavelengths that the filter will block.

This filter is currently in stock and available for immediate purchase through the vendor's website. The provided weblink leads directly to the product page for easy access and ordering. With its high-quality materials, precise specifications, and versatile applications, the 550FDN50 is an excellent choice for those seeking a reliable bandblocking dichroic filter.
