Our standard Solar Simulators produce an unfiltered xenon lamp spectrum. To approximate solar conditions for a variety of solar simulation applications we offer a complete line of Air Mass (AM) Filters. These filters modify the spectral output of the arc lamp to match specific natural solar conditions. The solar spectrum you wish to simulate determines which air mass filter you need. Use Table 1 as a guide.

| AM 0 |
Corrects the output of a xenon lamp to better match the solar spectrum found outside the earth's atmosphere. |

| AM 1.5 Global |
Matches the total (direct and diffuse) spectrum when the sun is at a zenith angle of 48.2° (ASTM E892) |
81388 |
| AM 1.5 Global |

Mounting
The Air Mass Direct Filters fit into the Solar Simulator's integral filter holder (shown in Fig. 2). A convenient "pull handle" allows quick and easy insertion and removal of the filter - without breaking down the source.
