My Notes

Nitrogen generator requires a 20 A circuit.

The reason they use aluminum mirrors. Aluminum has the highest reflectance in the UV/VIS region.

The reason you need a nitrogen purge

• In the UV below 240 nm the Xenon lamp can generare ozone from oxygen. Ozone can damage the optics.
• Oxygen abosorbs in the UV region. The xenon lamp already has very low emission intensity in that region
• Emission profile of some sources:

Linearly polarized light can be thought of as the superposition of right-hand circularly polarized light and left-hand circularly polarized light. See this youtube video for an excellent discussion.
