The 499 DM is a Dichroic Longpass Fluorescence Filter, manufactured by Iridian Spectral Technologies. This filter is designed with a rectangular base shape, measuring 35.6 mm in width and 25.2 mm in length, making it suitable for a wide range of optical applications. The filter has a thickness of 1.05 mm, providing durability and stability in its setup.
The 499 DM filter is cut on at 499 nanometers and cut off at 0 nanometers, making it a longpass filter. This means it allows transmission of longer wavelengths while blocking shorter ones. The specific wavelength for this filter is 588 nanometers.
The filter's coating is identical on both the front and back, with the front coating being 'iri 499-dm' and the back coating also being 'iri 499-dm'. This ensures consistent performance from both sides of the filter.
