Ultraviolet Solar Simulator Model 16S-300

Single output simulator of solar UV radiation in a region of 290 to 400 nm. The new 300 Watt lamp increases output intensity of the solar UV simulator by 1.5 to 2.0 times over the 150 watt models.  Higher output intensities decrease the test time inversely.   The UVA intensity doubles, the UVB increases somewhat less depending on the specific lamp.

APPLICATIONS

The model 16S-300 precisely reproduces the solar ultraviolet while eliminating the visible and infrared component. It results in UV levels with 10mm LLG is 15-20 times stronger than tropical sun without causing thermal discomfort or damage.

•clinical testing of light sensitive patients •SPF sunscreen testing •phototoxicity evaluations •material testing •UV curing



CONFIGURATION

Model 16S-300 comes with a 300 Watt xenon lamp and a precision power supply, Model XPS400, stabilizing the lamp current at a preset level. Automatic shutter and a PMA2100 / DCS, can be purchased separately to monitor the output and automatically control the delivered dose.

Illuminated area:  1 cm in diameter
Light source:  300 Watt xenon lamp
Lamp lifetime:  approx. 900 hours


FEATURES

An automatic internal igniter minimizes the electromagnetic interference. A fan provides cooling, increasing 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 selecting the output can be switched between UV-A only to a combined UV-A and UV-B spectrum.

Dimensions:  10.75x5.5x12" (27x14x30cm)

 

Main Components of the Model 16S Solar Simulator
  • 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.

Proper spot alignment at focusing lens holder, viewed from inside the Model 16S solar simulator
  • 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.
