Features

Air Mass Filters

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.

Air Mass Filter Mounting

The Air Mass Filters fit into the solar simulator's integral filter holder (shown in the image to the left). A convenient "pull handle" allows quick and easy insertion and removal of the filter - without breaking

Digital Exposure Controller

Our solar simulators have highly regulated power supplies to operate the lamps at constant power or current. However, with aging of the lamp and variables such as electrode erosion, gas absorption or desorption, the light output can change. These changes tend to be wavelength dependent. The68951 Digital Exposure Controller works with the power supply to compensate for these changes and ensure a stable, long-term output. It consists of a light sensing head, a controller, and a fiber optic probe. The silicon based light sensor monitors part of the light source output, and the controller constantly compares the recorded signal to the set level and changes the power supply output accordingly to keep the measured signal at the set level. Automatic detector gain setting allows the unit to work with 300 to 1600 W Large Area Illuminators. See Figure for an example of the effect of on the light output of a kW Solar Simulator.

Exposure Controller Mounting

Fig. 2 shows a diagram of the 68951 Exposure Controller picking off a part of the light output from a 1000 W Oriel® Solar Simulator. A fiber probe, mounted to the Simulator's output lens assembly, samples a small segment of the uniform portion of the output beam and feeds it to the light sensing head.

High Flux Beam Concentrator

The 81030 High Flux Beam Concentrator focuses the 2 x 2 inch (51 x 51 mm) output beam from our 1000 and 1600 W Solar Simulators down to a 0.6 inch (15 mm) diameter spot, increasing the energy density by 7X with a ±5% intensity uniformity. The output of the 81030 is equivalent to the intensity of 30 -50 suns (with a 1 kW source). It is very useful for high flux applications such as accelerated photodegradation studies and materials testing. All air mass filters are usable with the 81030.
