460FDS25 25 mm Dia. Shortpass Dichroic Filter 460nm
The 460FDS25 is a high-quality dichroic filter, 25 mm in diameter, designed for shortpass applications with a cutoff wavelength of 460nm. This filter is sourced from Knight Optical, a reputable vendor known for their extensive catalog of optical elements.
The filter is made of n-BK7 Schott, a widely used optical glass due to its excellent optical properties and high transmittance in the visible spectrum. The filter's geometry includes a diameter of 25mm and a thickness of 1.1mm, making it suitable for various optical systems.
The 460FDS25 features a dichroic coating on both the front and back surfaces, specifically the KNI 460FDS-0 coating. This coating is designed to reflect wavelengths shorter than 460nm while transmitting longer wavelengths, making it ideal for shortpass applications.
The filter's physical data includes a cut-on wavelength of 862nm, further enhancing its shortpass capabilities. The filter's shape is thin lens, which is often used in optical systems to minimize optical aberrations.
The 460FDS25 is currently in stock and available for purchase on Knight Optical's website. For more information, please refer to the provided weblink.
