535FDN12 12.5 mm Dia. Bandblocking Dichroic Filter 535nm
The 535FDN12 is a Dichroic Filter, specifically designed for bandblocking applications, with a diameter of 12.5 mm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components. The filter is made of n-bk7 schott material, a common choice for its excellent optical properties and durability.
The filter's primary function is to block light in the 435-635nm range while allowing light at the 535nm wavelength to pass through. This is achieved through a precise coating on both the front and back surfaces, denoted as 'kni 535fdn-0'. This coating is designed to optimize the filter's performance for its specified wavelength and blocking range.
The filter has a thickness of 1.1 mm, which is considered thin in the context of optical components. This thinness, combined with its circular shape, gives the filter a 'Thin Lens' geometry. This geometry may offer certain advantages in specific optical systems, depending on the application.
The 535FDN12 is currently in stock and available for purchase through the vendor's website. The link to the product page is provided in the item data for your convenience.
