The model 16S precisely reproduces the solar ultraviolet spectrum while eliminating the visible and infrared component. This results in UV levels 15-20 times stronger than tropical sun without causing thermal discomfort or damage.

The model 16S comes with a 150 Watt xenon lamp and a precision power supply. The model XPS200 power supply stabilizes the lamp current at a preset level. An automatic shutter and a PMA2100 / DCS, can be purchased separately to monitor the output and automatically control the delivered dose.
Exposure sizes 1cm to 2.5" spot diameter
An automatic internal igniter minimizes the electromagnetic interference. A fan provides cooling and increases lamp life. The solar simulator is attached to the power supply with a 5ft cable and a quick disconnect connector.
By moving an optical filter, the output can be switched between UV-A only to a combined UV-A and UV-B spectrum.
Model 16S Solar Simulator
Spectral output: Follows the distribution of sunlight from 290 to 400 nm
Light source: 150 Watt xenon lamp
Lamp lifetime: approx. 900 hours
Dimensions: 10.75x5.5x9.5" (27x14x24cm)
- The retro mirror produces the secondary spot, which increases the output by about 30%. The secondary spot should be adjusted to produce a spot the same size as the primary spot.
- The collimating lens collects the light from the lamp and focuses the light to an adjustable size producing the primary spot.
- The dichroic mirror reflects the UV light and transmits the visible and IR light. The thin film on the dichroic faces the lamp. Low output will result if the dichroic is installed backwards.
- The focusing lens focuses the light to a uniform spot. It also houses the WG320 and UG11 filters to shape the spectrum.
- The top two figures show good alignment of the lamp. The primary and secondary spots are in the center of the focusing lens. The orientation of the spots can be horizontal or vertical.
- The bottom two figures are examples of poor lamp alignment. The result will be a decrease in output and a non-uniform spot. Adjustment of the lamp and retro mirror is required for increased output.
