The 470FDS25 is a high-quality dichroic filter, sourced from Knight Optical, designed for shortpass applications with a 470nm cutoff wavelength. This filter is circular in shape, featuring a 25mm diameter and a thickness of 1.1mm, making it suitable for a wide range of optical systems.
The filter is constructed using n-BK7 Schott material, a popular choice due to its excellent optical properties and versatility. The coating on both the front and back surfaces of the filter is KNI 470FDS-0, which is specifically designed to achieve the desired shortpass characteristics.
The physical data of the filter is also noteworthy. With a cut-on wavelength of 826nm, it effectively blocks longer wavelengths while allowing shorter wavelengths to pass through. This makes it ideal for applications where the differentiation of specific wavelength ranges is crucial.
The 470FDS25 is currently in stock and available for immediate purchase from Knight Optical's website.
