543FDN12 12.5 mm Dia. Bandblocking Dichroic Filter 543nm

The 543FDN12 is a Dichroic Filter, specifically designed for bandblocking, offered by Knight Optical. This filter has a catalog number of 543FDN12 and is available directly from the vendor's website, with a current status indicating it is in stock.

This circular filter boasts a diameter of 12.5 mm and a thickness of 1.1 mm, making it a compact yet effective optical component. The base shape is a Thin Lens, and the material used in its construction is n-bk7 schott, a popular choice for its excellent optical properties.

The 543FDN12's primary function is to block light in the wavelength range of 461nm to 625nm, while allowing light at the center wavelength (CWL) of 543nm to pass through. This is achieved through the application of a specialized coating, denoted as 'kni 543fdn-0' on both the front and back surfaces of the filter.
