67-738 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 239nm
The 67-738 is a mounted traditional coated bandpass interference filter, available from Edmund Optics. This filter has a 12.5 mm diameter and a thickness of 3.5 mm, making it suitable for various optical applications. The filter is designed to transmit light in the center wavelength (CWL) of 239 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity in wavelength transmission makes it ideal for applications requiring precise light filtering.
The filter's cut-on wavelength is 234 nm, and the cut-off wavelength is 244 nm. This means that it begins to transmit light at 234 nm and stops transmitting at 244 nm, further enhancing its ability to filter specific wavelengths. The filter is made from UVFS Mal-1965 material, which is known for its durability and performance in ultraviolet applications.
The 67-738 filter features a thin lens shape and is coated on both the front and back surfaces with EDM 67-738, a proprietary coating from Edmund Optics. This coating enhances the filter's performance and durability, ensuring reliable operation in various conditions. The filter is currently in stock and can be purchased directly from the Edmund Optics website, with the provided weblink providing a direct path to the product page.
