500FDL25 25 mm Dia. Longpass Dichroic Filter 500nm

The 500FDL25 is a Dichroic Filter, specifically designed for longpass applications with a cut-on wavelength of 500nm. This filter is sourced from Knight Optical, a renowned vendor known for their high-quality optical components. The filter is designed with a circular geometry, featuring a diameter of 25mm 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 glass due to its excellent optical properties and high damage threshold. The coating on both the front and back of the filter is KNI 500FDL-0, which is specifically designed for longpass applications at 500nm. This coating ensures high transmission of light above the cut-on wavelength and efficient reflection of light below it.

The 500FDL25 is designed in the shape of a thin lens, which can be beneficial in certain optical systems where minimal thickness is required. The filter is currently in stock and available for immediate purchase through the vendor's website.
