Unformatted text preview: er noise is caused by variations in experimental variables that control the source intensity, such as power supply voltages and temperature. It can also be caused by mechanical variations such as vibrations. (e) Cell positioning uncertainty is caused by our inability to position the cell in the same exact place each time. A random variation is introduced because the incident beam is imaged onto slightly different portions of the cell walls each time causing differences in the reflection, transmission and scattering characteristics of the cell. (f) A beamsplitter is a device that causes an incident beam to divide into two beams at its output. It can be made from mirrors, rotating choppers, or optical materials that cause a beam to be split into two beams....
