420FDL12 12.5 mm Dia. Longpass Dichroic Filter 420nm

The 420FDL12 is a Dichroic Filter, specifically designed for longpass applications with a cut-on wavelength of 420nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components. The filter is designed with a circular geometry, featuring a diameter of 12.5mm and a thickness of 1.1mm, making it suitable for a wide range of optical applications.

The filter is made from N-BK7 Schott, a popular optical material known for its excellent optical properties and versatility. The coating on both the front and back surfaces of the filter is KNI 420FDL-0, which is specifically designed to enhance the filter's performance in longpass applications.

The physical data of the filter indicates that it is a longpass filter with a cut-on wavelength of 420nm. This means that it will pass light with a wavelength of 420nm and above, while blocking or attenuating light with a shorter wavelength. The filter is designed to be thin, which is beneficial for applications where space is a constraint.

The filter is currently in stock and available for purchase on Knight Optical's website. For more information, you can visit the following link: https://www.knightoptical.com/stock/default/dichroic-filter-longpass-420nm-dia-12-5mm.html
