550FDS25 25 mm Dia. Shortpass Dichroic Filter 550nm
The 550FDS25 is a high-quality dichroic filter, sourced from Knight Optical, designed for shortpass applications with a 550nm 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 glass, a material known for its excellent optical properties and high damage threshold. This ensures the filter can withstand rigorous use while maintaining its performance. The filter's coating, KNI 550FDS-0, is applied to both the front and back surfaces, further enhancing its shortpass capabilities.
The 550FDS25 has a cut-on wavelength of 788nm, meaning it begins to transmit light at this wavelength and above, while effectively blocking light below 550nm. This makes it ideal for applications where the rejection of shorter wavelengths is crucial.
Knight Optical, the vendor, provides a valid weblink, indicating that the filter is in stock and readily available for purchase. The company's reputation for quality and service makes this filter a reliable choice for your optical needs.
