Polarization
Malus' law
- 1 optical rail
- 2 post holders
- Lamp (w/ LED bulb)
- Polarizer on a post
- Light intensity sensor on a post
- Stick-on polarizer sheet (w/ magnet)
- Adjustable +/-24 V power supply
- 2 multimeters
- 2 BNC to double-banana cables
- 2 patch cords (1 red, 1 black)

NOTE: Make sure to test light sensors to make sure the batteries are not dead. Input bias should be set to -12 V (the maximal negative voltage) and the output should vary over the range of at about 0-100 mV as polarizer is varied. Alignment is critical (check height and angle of light sensor), and try to block out extraneous light from the lamp.
Brewster's angle
- Analog optical spectrometer
- Glass slide with black tape in post holder
- Polarizer cap
- Lamp (w/ LED bulb)
- USB webcam in mount
- Dark cloth (not really needed, but nice to have)
