550FDL12 12.5 mm Dia. Longpass Dichroic Filter 550nm

The 550FDL12 is a Dichroic Filter, specifically designed for longpass applications with a cut-on wavelength of 550nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components. The filter is made from N-BK7 Schott, a widely used optical glass due to its excellent optical properties and durability.

The filter has a circular shape with a diameter of 12.5mm and a thickness of 1.1mm, making it suitable for a wide range of optical applications. The coating on both the front and back surfaces is KNI 550FDL-0, which contributes to its longpass dichroic properties.

The physical data of the filter indicates that it cuts off wavelengths below 550nm, allowing only longer wavelengths to pass through. This makes it ideal for applications where the separation of shorter and longer wavelengths is required.

The filter is in stock and available for immediate purchase through the vendor's website. For more information, you can visit the provided weblink.
