• 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.
