33-328 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 631nm
The 33-328 is a 50 mm diameter Bandpass Filter, specifically designed for fluorescence applications, with a center wavelength of 631nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase on their official website. The product link and stock status are provided in the item data for your convenience.
The filter is made from UVFS Mal-1965 material, a common choice for optical elements due to its excellent properties. It features a circular base shape, a thickness of 2mm, and a thin lens shape, making it suitable for a wide range of applications.
The physical data of the filter includes a cut-on wavelength of 620.5nm and a cut-off wavelength of 641.5nm, with a Central Wavelength (CWL) of 631nm. This means the filter allows light within this specific wavelength range to pass through while blocking other wavelengths, making it ideal for applications requiring wavelength selectivity.
The filter is hard coated with EDM 33-326 on both the front and back surfaces, enhancing its durability and performance. This coating also helps to reduce reflections and increase transmission, further improving the filter's efficiency.
