11-984 25 mm Dia. First Surface UV Bandpass Filter; t=1.5 mm 220nm
The 11-984 is a 25 mm diameter First Surface UV Bandpass Filter, with a thickness of 1.5 mm and a central wavelength of 220nm. This filter, offered by Edmund Optics, is designed to transmit light within a specific range of wavelengths while blocking other wavelengths.
The filter's bandpass characteristics are defined by its cut-on wavelength at 215nm and cut-off wavelength at 225nm. This means it allows the passage of light in the narrow band between these two wavelengths, making it ideal for applications that require precise wavelength selection in the ultraviolet spectrum.
The filter is made from UVFS MAL-1965 material, a unique substrate specifically designed for UV applications. It features a front and back coating of EDM 11-984, which enhances its performance and durability. The filter's thin lens shape further adds to its versatility, making it suitable for a wide range of optical systems.
