ThAr Lamps

The lamps are not labeled with the corresponding identifiers due to the fact there is no convenient way to label each lamp. Thus we are relying on people placing the proper lamp in the proper box.

The lamp characteristics are as follows. Click on the lamp ID to see a sample spectrum. Each lamp has a different spectrum and the differences may be significant.

All sample lamp spectra were taken with the same parameters: 18 mA current, 20 second exposure with the 100:25 (focus) aperture with dewar 4.
