14-918 50 mm Dia. First Surface UV Bandpass Filter; t=1.5 mm 239nm
The 14-918 is a 50 mm diameter First Surface UV Bandpass Filter, with a thickness of 1.5 mm, specifically designed for use at a central wavelength of 239nm. This filter, offered by Edmund Optics, is a Bandpass Filter, which allows light to pass through a specific range of wavelengths while blocking other wavelengths.
The filter's geometry includes a diameter of 50 mm and a thickness of 1.5 mm, making it suitable for various optical applications. The physical data of the filter includes a cut-on wavelength of 234nm and a cut-off wavelength of 244nm, with a central wavelength of 239nm. This specificity in wavelength range ensures optimal performance in UV applications.
The 14-918 filter features a coating on both the front and back surfaces, specifically the EDM 11-988 coating. This coating enhances the filter's performance and durability, ensuring reliable operation in its intended application.
The filter's shape is described as a Thin Lens, which is a lens with a very small focal length compared to its diameter. This shape allows for efficient light transmission and focusing, making it ideal for various optical systems.
