The 497 DM is a Dichroic Longpass Fluorescence Filter, manufactured by Iridian Spectral Technologies. This filter, with a catalog number of 497 DM, is available for purchase directly from the vendor's website, as indicated by its 'Valid - in stock' status.
The filter is rectangular in shape, with a width of 35.6 mm and a length of 25.2 mm, making it suitable for various optical applications. It has a thickness of 1.05 mm, providing durability and stability. The 497 DM filter is made from UVFS Mal-1965 material, a common choice for optical components due to its excellent transmission properties.
The 497 DM filter is designed to cut on at 497 nm and has no specified cut off. This longpass characteristic allows for the transmission of longer wavelengths, making it ideal for fluorescence applications where a specific excitation wavelength needs to be isolated.
The filter's coating is identical on both the front and back surfaces, with the iri 497-dm coating. This coating ensures optimal performance and durability, enhancing the filter's longevity and effectiveness in its intended applications.
The filter's shape is described as a Thin Lens, indicating its potential use in focusing or collimating light beams. This versatile filter is a valuable addition to any optical system requiring longpass fluorescence filtering.
