ADJUSTING UNIFORMITY
Both of the mirrors in this solar simulator are adjusted and locked into
position at OAI.
Should the mirrors require adjustment to achieve the required
uniformity, the adjustments are located on the rear of the main housing and on
the front of the lens housing. The primary mirror, located above the ellipsoidal
reflector, should be adjusted to maximize the intensity of the beam measured in
the center of the exposure area. Adjusting the orientation of the secondary
mirror, located above the collimating lens, can be adjusted as required to achieve
the desired beam uniformity.
The integrator adjustment is preset by
OAI
for the maximum possible intensity,
within our uniformity specification, across the largest target area that will fit the
lens diameter. The solar simulators are tuned for a uniformity of +2%. The
integrator adjustment allows for higher intensity within a smaller target, or
superior uniformity at a lower energy level.
It is not advisable to perform this
adjustment with the shutter open.
NOTE
Care must be taken not to touch the lenses in the condensing lens array as
permanent damage can result if the Solar Simulator is operated with lenses
soiled by fingerprints. If lenses are touched, a soft lens tissue may be used
to clean only the area with the fingerprint. Do not attempt to remove and
disassemble this unit for cleaning. This should be performed only at OAI.
