Explore the magnetic field spirit beside you to enrage at any time and place, ghostliness detector can tell you the answer with color lamp, be careful!

According to emission lines and the relation between detector size and system bandwidth, we designed the spectral calibration plan for SHS, which uses tunable laser and halogen lamp.

In experiments, we used the 2793k halogen tungsten lamp to irradiate the detector of CCD143A and measured the values of photometry and radiometry.
