  1. Design of CCD Array Detector for a Czerny-Turner Spectrograph Brennan Thomason Tamara Reed Edmond Wilson

  2. 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)

  3. 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

  4. Sony ILX511 CCD Linear Array Detector

  5. SONY ILX511 This device has 2048 CCD pixels, 14 μm wide x 200 µm high

  6. SONY ILX511Spectral Operating Range

  7. SONY ILX511Timing Diagram

  8. SONY ILX511Internal Circuit

  9. Sony ILX511External Circuit

  10. Revised Circuit Schematic

  11. PCB Design

  12. 3D Renderings of the PCB

  13. 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.
