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.
