538FDN12 12.5 mm Dia. Bandblocking Dichroic Filter 538nm
The 538FDN12 is a Dichroic Filter, specifically designed for bandblocking, offered by Knight Optical. This filter is characterized by a circular shape with a diameter of 12.5 mm and a thickness of 1.1 mm, making it a compact and convenient option for various applications.
The filter's primary function is to block light in the range of 449-628 nm, while allowing light at the center wavelength (CWL) of 538 nm to pass through. This is achieved through a precise coating on both the front and back surfaces, labeled as 'kni 538fdn-0'. This coating is applied to a base material of n-bk7 schott, a common and reliable material in optical applications.
The 538FDN12 is currently in stock and available for purchase on Knight Optical's website. The catalog number for this item is 538FDN12, and it can be found at the following link: https://www.knightoptical.com/stock/default/dichroic-filter-bandblocking-449-628nm-dia-12-5mm.html
