550FDS12 12.5 mm Dia. Shortpass Dichroic Filter 550nm
The 550FDS12 is a high-quality dichroic filter, 12.5 mm in diameter, designed for shortpass applications with a cutoff wavelength of 550nm. Sourced from Knight Optical, a renowned vendor in the optical industry, this filter is built to exacting standards, ensuring reliable performance and consistent results.
This filter is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and durability. It features a dichroic coating on both the front and back surfaces, designated as KNI 550FDS-0. This coating is specifically designed to reflect wavelengths shorter than 550nm while transmitting longer wavelengths, making it ideal for a wide range of applications.
The 550FDS12 has a physical cut-on wavelength of 788nm and a cutoff wavelength of 550nm. It has a thickness of 1.1mm, which is suitable for most optical systems. The filter's thin lens shape allows for easy integration into various setups.
The 550FDS12 is currently in stock and available for immediate purchase. For more information, you can visit the product page at https://www.knightoptical.com/stock/default/dichroic-filter-shortpass-550nm-dia-12-5mm.html.
