4 FILTER INSTALLATION / REPLACEMENT
The 94011A(-ES) solar simulator includes an AM1.5G spectral correction filter. It shapes the light output to
closely match the total (direct and diffuse) solar spectrum on the Earth’s surface, at a zenith angle of 48.2°
(ASTM 892). This provides a Class A irradiance spectrum suitable for Photovoltaic cell testing.
The filter is shipped in its own case. Note that the solar simulator should not be transported with the filter in
place. Save this case for storage of the filter.
The coated side is mounted on the side with the screw heads showing, and must face the lamp, as shown.
Installation and replacement
1. Disconnect the LCS-100
TM
from the AC mains.
2. Remove the LCS-100
TM
top cover by removing the top 4 Phillips head screws only. Do not loosen
or remove the bottom 4 Phillips head screws. Lift the top cover up straight to remove.
3. It is easier to remove and install the filter assembly without a lamp installed, and can avoid
damage to the filter and lamp. This is recommended.
4. Remove the two thumbscrews as shown in Figure 7, and set aside.

5. If a filter assembly is in place to be removed, slide it off the two retaining studs while grasping it as
shown in Figure 8.
6. Lift it out slowly, being careful that the filter does not get scratched or dropped. Place it into
protective packaging.
