Build Spectrophotometer and measure light source efficiencies

Build a Home-made Spectrometer and estimate Quantum Efficiency of various light sources
Observation & Data to be Recorded-

  1. Wavelength v/s Intensity (ƛ v/s Int.)
  2. Calibration Curve for Spectrometer
  3. (ƛ v/s Int.) graph for various light sources
  4. Integrating Curves to Find QE and Find the area under the curve
  5. Estimation of the output power of light sources by current/voltage specifications
