581FDS12 12.5 mm Dia. Shortpass Dichroic Filter 581nm

The 581FDS12 is a high-quality dichroic filter, sourced from Knight Optical, a leading vendor in the optical industry. This filter is designed with a circular shape, featuring a diameter of 12.5 mm and a thickness of 1.1 mm, making it suitable for a wide range of optical applications.

The filter is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and durability. The N-BK7 Schott material ensures high light transmission and low auto-fluorescence, making it an ideal choice for applications that require high-precision optical filtering.

The 581FDS12 is a shortpass dichroic filter, designed to reflect wavelengths below 581nm and transmit wavelengths above 588nm. This specific wavelength range makes it suitable for applications that require the separation of specific light wavelengths, such as in spectroscopy, fluorescence microscopy, and other laser-based applications.

The filter's coating is another notable feature. Both the front and back surfaces of the filter are coated with KNI 581FDS-0, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, providing improved wavelength selectivity and higher damage threshold.

The 581FDS12 is currently in stock and available for immediate shipping. For more information, you can visit the product page at https://www.knightoptical.com/stock/default/dichroic-filter-shortpass-581nm-dia-12-5mm.html.
