516 DM 35.6 x 25.2 mm Dichroic Longpass Fluorescence Filter; t=1.05mm 520-700nm

The 516 DM is a Dichroic Longpass Fluorescence Filter, manufactured by Iridian Spectral Technologies. This filter, with a catalog number of 516 DM, is available for purchase directly from the vendor's website, as of the time of this description. The filter is designed to be rectangular in shape, with dimensions of 35.6 mm in width and 25.2 mm in length, making it suitable for a variety of optical applications.

The filter has a thickness of 1.05 mm, providing a balance between durability and precision. It is designed to cut on at 516 nm and has no specified cut off, making it ideal for use in longpass fluorescence applications. The coating on both the front and back of the filter is 'iri 516-dm', which is a proprietary coating developed by Iridian Spectral Technologies. This coating ensures high transmission and excellent blocking performance, making the filter highly effective in its intended use.

The filter is designed in the shape of a thin lens, which allows for efficient light transmission and minimal distortion. This makes it an excellent choice for applications that require high-quality imaging, such as microscopy or fluorescence spectroscopy.
