The 550FDS50 is a high-quality dichroic filter, measuring 50 x 50 mm, designed for shortpass applications with a cutoff wavelength of 550nm. This filter is sourced from Knight Optical, a renowned vendor known for their extensive catalog of optical elements.
The filter is made from N-BK7 Schott, a popular optical glass due to its excellent homogeneity, low auto-fluorescence, and high damage threshold. The filter's geometry includes a thickness of 1.1mm, making it suitable for a wide range of optical applications.
The 550FDS50 features a coating on both the front and back surfaces, specifically 'kni 550fds-0'. This coating is designed to enhance the filter's performance, ensuring a sharp cutoff at the specified wavelength. The filter's shape is that of a thin lens, further expanding its potential applications.
The physical data of the filter includes a cut-on wavelength of 788nm, adding to its shortpass capabilities. The filter is currently in stock and available for immediate purchase through the vendor's website, with the weblink provided in the item data for convenience.
