Design of CCD Array Detector for a Czerny-Turner SpectrographBrennan ThomasonTamara ReedEdmond Wilson
Project Goal• Design a detector for a high resolution
spectrograph that provides electromagnetic radiation intensity data as a function of wavelength in the range of 400 nm to 1000 nm.• Compete in the National Student Solar
Spectrograph Competition (NSSSC)
Design Objectives• Sensitive over entire visible range• Capable of high resolution measurements• Record data at a rapid rate• Easy to program• Detector must be robust

Wavelength Calibration(Mercury Vapor Lamp)
• Without a reference, it is difficult to make sense of the results we obtain.
• By calibrating with a known spectrum such as mercury vapor, we obtain this reference point.
