625FDL25 25 mm Dia. Longpass Dichroic Filter 625nm by Knight Optical

The 625FDL25 is a high-quality Dichroic Filter, longpass type, with a specified wavelength of 625nm, sourced from Knight Optical. This filter is designed with a circular shape, 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 well-known and widely used optical glass, ensuring durability and reliability. The filter's coating, kni 625fdl-0, is applied on both the front and back surfaces, contributing to its excellent optical performance.

The 625FDL25 is a longpass filter, meaning it allows light of longer wavelengths to pass through while blocking or reflecting shorter wavelengths. In this case, the cut-on wavelength is 625nm, indicating that it starts to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than 625nm.
