510FDL25 25 mm Dia. Longpass Dichroic Filter 510nm by Knight Optical

The 510FDL25 is a high-quality dichroic filter, specifically designed for longpass applications with a cut-on wavelength of 510nm. This filter, sourced from Knight Optical, is a circular element, boasting a diameter of 25mm and a thickness of 1.1mm, making it a versatile choice for various optical systems.

The filter is constructed from N-BK7 Schott, a widely used borosilicate glass known for its excellent optical properties and durability. This material ensures the filter maintains its performance even under demanding conditions. The filter's coating, KNI 510FDL-0, is applied to both the front and back surfaces, enhancing its longpass capabilities and providing a high transmission rate for wavelengths above 510nm.

The 510FDL25 features a thin lens shape, which is beneficial for applications where space is a constraint. It is currently in stock and available for immediate dispatch, as indicated by its weblink status. For more detailed information or to make a purchase, users can visit the provided weblink.
