Reflectance and Transmission
- Don’t let laser light fall into your eyes.
- Block all unused reflected laser beams.
- Tighten the mounts after adjustments and experiments.
- Do not switch off or on the electronics directly from the mains.
- Don’t touch the optical surfaces directly with hand i.e. glass plate and the polarizer for this experiment.
- For reflectance measurement, the photodiode has to be moved each time the angle of incidence is changed. Make sure to get a maximum reading on the photodiode, slightly adjust it up & down to get the maximum reading.
