67-818 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 307nm
The 67-818 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 3.5 mm, specifically designed for a central wavelength (CWL) of 307 nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase directly from their website, with the status indicating it is currently in stock.
The filter is characterized by its bandpass properties, which allow it to transmit light within a specific range of wavelengths while blocking other wavelengths. This particular model has a cut-on wavelength of 302 nm and a cut-off wavelength of 312 nm, making it ideal for applications that require narrow-band light transmission around the 307 nm mark.
The 67-818 filter is made from UVFS Mal-1965 material, a detail that may be crucial for users who require specific material properties for their applications. It features a thin lens shape and comes with front and back coatings of EDm 67-751, enhancing its performance and durability.
