The Monochromator

The goal of this project is to refurbish an old Monochromator and optimize it for use in future labs. The device was tested to ensure basic functionality and to determine the best way to approach the project. A detection circuit was built to allow data from the device to be collected by a computer. This was done using a photodiode to detect changes in light and an operational amplifier to boost the signal. LabView software was used to interpret the data sent to the computer and create an output file that could be easily understood. The data collected during tests was then analyzed in order to establish the limitations of the device and its possible uses in future labs. These tests included viewing the light spectra of various gases such as Sodium, Hydrogen and Deuterium. A lab manual containing directions and lab experiments will be written to assist future students.
