Each station gets 3 plastic linear polarizers. One for each student to use at the beginning of the lab for a TA led exercise illustrating what they do. I typically use the ones from the old Photoelectric Effect lab that are found in room 112.

All components for this part of the lab are kept in the third wall cabinet from the door on the east wall. The optical rails are stored atop the cabinet, but should already be out from the previous week's Optic's lab.

Both lenses and the translucent screen from the Optic's lab are not needed and should be put away. In addition to the light source, which should be left out from last weeks lab, each setup also needs:

• Two linear polarizers.
• One light sensor holder.
• One light sensor. The light sensor's are stored together in a box with the rest of the apparatus parts.
• One LabQuest Mini with a USB cable. There are about 10 LabQuest Mini's and USB cables with the rest of the parts.
• Logger Pro installed on the computer and the Light Sensor configuration file on the desktop. This configuration simply displays the output of the light sensor in real time, no plotting of the data is necessary.

The light sensor connects to channel 1 of the LabQuest Mini and the range selector should be set to the middle position, 0 - 600 lux.

Note that there is a translucent screen shown in the photo. It is mentioned in the lab wiki, but I am not sure why so it might not need to be left out.

Parts I usually put out include:

• Kevin's cross polarization viewer.
• One piece of the yellow squishy material.
• One piece of Quartz.

The viewers are stored in the cabinet with the rest of the optical apparatus. The other two items are usually in room 112.

For this part each station should have one spectrometer, a microscope slide in it's holder and a white light source. The spectrometers are usually in room 112. The light lamps can be found in the 3rd cabinet.

Note that I do not use the video cameras, instead having students look through the eyepiece. There are just too many problems with how the video cameras are held onto and centered on the eyepiece that I think they are not worth their benefits.

In the past I have been able to setup one spectrometer per station so that each station has a complete set of all parts. But recently shortages have led to fewer spectrometer setups, so I put out as many as I can and have students rotate through them.
