Has lever than will change amount of light hitting sample
Light source location
On the base of microscope
Voltage (light) setting function and location
Control brightness of light from bulb
At base
Coarse focus location and function
Large knob on the side (has smaller knob attached)
Moves stage up and down
Fine focus location and function
On side of microscope attached to coarse knob
Focus on image
X/Y knob location and function
Hangs below stage on pipe
Used to move slide around stage

Spectrophometer function
Allows you to determine which wavelengths of light a chemical absorbs
How is spectrophometer used to measure enzyme activity in the reaction
Shows where peak absorbance occurs / enzyme activity is highest
