Air Mass Filter, AM 1.5 Direct, Glass Only

The 81389R Air Mass Filter simulates the solar spectrum from directional rays at a zenith angle of 37.0° to ground level. It does not account for sunlight that is scattered by the atmosphere or diffusely reflected off other objects. This is only sunlight that transmits directly through the atmosphere to the surface of the earth.
This 2 inch x 2 inch filter fits into a solar simulator's integral filter holder, sold separately, or can be mounted into an external filter holder which will flange to the Oriel® Research Arc Lamp Housings. The 81389R is an AM Direct type filter which meets the AM 1.5 D spectrum per the ASTM E 891 standard.
