The 11-996 is a 25 mm diameter First Surface UV Bandpass Filter, with a thickness of 1.5 mm, designed for use in applications requiring a narrow bandwidth centered at 300nm. This filter, offered by Edmund Optics, is a Bandpass Filter, specifically designed to transmit light within a certain range of wavelengths while blocking other wavelengths.
The filter's physical data includes a cut-on wavelength of 295nm and a cut-off wavelength of 305nm, ensuring a tight bandwidth of 10nm (Full Width at Half Maximum, FWHM). The Central Wavelength (CWL) is 300nm, right at the center of the transmission range.
The 11-996 filter features a UVFS MAL-1965 material ID, which is specifically designed for UV applications. The filter's geometry includes a diameter of 25mm and a thickness of 1.5mm, making it suitable for use in various optical systems.
The filter's coating includes a front and back coating of EDM 11-996, which is designed to enhance the filter's performance and durability. The filter's shape is that of a Thin Lens, which is often used in optical systems to reduce spherical aberration and improve image quality.
According to the vendor's information, the filter is currently in stock and available for immediate purchase. The filter's catalog number is 11-996, and more information can be found on the Edmund Optics website.
