67-813 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 280nm
The 67-813 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 3.5 mm, specifically designed for use at a central wavelength (CWL) of 280nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase directly from their website.
The filter is characterized by its bandpass properties, which allow it to transmit light within a specific range of wavelengths while blocking out unwanted light from other regions of the spectrum. This is particularly useful in applications where it is necessary to isolate specific wavelengths for analysis or processing.
The 67-813 filter features a cut-on wavelength of 275nm and a cut-off wavelength of 285nm, indicating a narrow bandwidth that is ideal for precise optical measurements. The filter's coating, denoted as EDM 67-746 on both the front and back surfaces, provides additional protection and enhances the filter's performance.
The filter's geometry is another notable feature. With a diameter of 25mm, it is suitable for use in a wide range of optical systems. The thickness of 3.5mm provides structural rigidity while minimizing the impact on the overall optical path length.
