Projector Capability Experiment
ObjectiveThe primary objective of this experiment was to project, measure and analyze the intensity of our light source in order to make a determination regarding material selection for the bottom surface of the resin bath. This test was made possible due to assistance from the College of Imaging Science. Spectral data was collected as light was measured under varying conditions by placing panes of glass in front of the projector. The conditions for the test were as follows:
- Projector Lens Without Quartz Lens Cap
- Projector Lens With Quartz Lens Cap
- Lens Cap + Plexiglass
- Lens Cap + Soda Lime Glass
- Lens Cap + Fused Silica Glass
Each of these materials are candidates for the bottom surface of the resin bath. Ideally the material that allows transmission of the most UV light would be selected.
Graphical displays of the test results are shown below.
