(AMF-AM1.5D) AM1.5D Air Mass Filter

An AM1.5D filter compatible with Sciencetech solar simulators, including FT-style filter holder. Filter clear aperture is a diameter of 76 mm (3"). Please select the product line the filter is intended to be used with to ensure the proper spectral output.

AM1.5D simulates the terrestrial solar spectrum on the ground when the sun is at a zenith angle of 48.2°. It includes only direct light from the sun, and not the diffuse light that is scattered by the atmosphere. As a result, this filter simulates the direct radiation which reaches the ground.

Please note that for some simulator models the same filter is used to supply an AM1.5G spectral match. Purchasing separate AM1.5G and AM1.5D filters for the same model simulator may not provide a different spectrum.
