Features

Air Mass Filters

Our lamp-based Solar Simulators produce an unfiltered Xenon 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. An Air Mass filter is chosen by the type of solar spectrum that needs to be simulated. Our filters can be easily replaced in the solar simulator to enable quick, reliable customization of the output spectrum.

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" in the frame allows for quick, easy insertion and removal of the filter - without risk of breaking.

Digital Exposure System

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 System 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 solar simulator models. Refer to the figure to the right for an example of the effect of on the light output of a 1.0 kW Solar Simulator.

Exposure System Detection Mounting

The figure to the left shows a diagram of the 68951 Exposure System's detection head picking off a portion 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 Si detector connected to the digital exposure controller.

High Flux Beam Concentrator

The 81030 High Flux Beam Concentrator is compatible with 3 Solar Simulator models: 94023A, 91291, and 92191. It focuses the 2 inch x 2 inch (51 mm x 51 mm) output beam from our 1000 and 1600 W Flood Exposure Systems 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 1 kW source 91291). 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.

Solar Simulator Safety

Arc lamps may emit dangerous levels of UV radiation depending on their source type. Ensure that only authorized personnel are in the vicinty of the source, and wearing the necessary safety equipment such as UV protective eyewear, clothing, and gloves. Lighted UV warning signs, posted outside laboratory doors where UV sources are operating, can prevent accidental exposure. Newport also recommends using an electronic shutter to block the beam when the source is not in use but remains turned on. Alternatively, the beam can be safely contained by using beam tubes or fiber optic cables to deliver the light to a sample. It is recommended to vent the ozone that is produced by some lamp models to the outside or use an Ozone Eater.
