Sciencetech solar simulators for high intensity, uniform illumination

Scitech presents solar simulators from Sciencetech Inc., designed to produce
high intensity, uniform illumination on a target area.

Typically, high power solar simulators use an ellipsoidal reflector to
capture light from an arc lamp source inside the reflector, an arrangement that
results in a light pattern with a bright outer region and a dark centre. This
non-uniformity is unacceptable in many solar simulator applications, forcing many
solar simulator models in the market to use designs involving diffusers to
reduce the non-uniformity. This results in a reduction of intensity and a
distortion of the spectrum on the target area.

Sciencetech has resolved these problems by using a unique system of
mirrors that ‘fold’ the light onto the target plane, effectively reducing the
light that is lost with little to no spectral distortion while also eliminating
chromatic aberration in the output beam.

In addition, each of Sciencetech’s solar simulators is customisable to
best suit your requirements. The design of the fully reflective solar simulator
permits a trade-off between power and uniformity. Higher uniformity can be
achieved with lower power, or power can be increased when uniformity is

Sciencetech designs and fabricates more than 30 different variants of
solar simulators. The company also manufactures light sources, monochromators
and other optical spectroscopy instruments as well as far infrared Terahertz
spectroscopy systems, photovoltaic testing equipment, and custom made
