The 539FDN12 is a Dichroic Filter, specifically designed for bandblocking, with a diameter of 12.5 mm. This filter is sourced from Knight Optical, a reputable vendor known for its 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 462-615nm range while allowing light at the center wavelength (CWL) of 539nm to pass through. This makes it ideal for applications where specific wavelengths need to be isolated or blocked. The filter's thickness is 1.1mm, providing a good balance between robustness and light transmission.
The coating on both the front and back of the filter is KNI 539FDN-0, which is specifically designed for this type of filter. The filter's shape is that of a thin lens, which is often used in optical systems due to its minimal thickness and weight.
