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.

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.

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. The 68951 Digital Exposure Controller works with the power supply to compensate for these changes and ensure a stable, long-term output. See Fig. 1 for an example of the effect of the 68951 on the light output of a kW Solar Simulator.
Fig. 1 The effect of the 68951 Digital Exposure Controller on the output of a 1000 W Solar Simulator.
The 68951 is made up of a light sensing head, a controller, and a fiber optic probe. The silicon based light sensor monitors part of the light source output (via the fiber probe), 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.
The 68951 also allows timed exposures. The 68951 is capable of exposure times from 10 ms to 9999 hours, in increments as short as 10 ms. However, the mechanical response time of the shutter in our Solar Simulators limits the minimum exposure time to 100 ms, and the shortest interval between exposure to 80 ms. For those instances when a timed exposure is not sufficient, you can use the auto-dose mode to keep the shutter open until the total flux equals a user set value.
The 68951 is intended to work specifically with Oriel® Solar Simulators, where there is a light shutter between the sensor head and the arc lamp. When the shutter closes, the idle system maintains the lamp at its rated power; this ensures that when the shutter is closed the 68951does not compensate for lack of signal by commanding the power supply to increase power to the lamp.
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.
