Steve and I visited Margot to have a training session for application of First Contact on optics.
- Make "thick" layer of first contact. It becomes thin when it gets dried.
- Apply more FC once a peek sheet is placed on the FC
- Wait for drying (~15min)
- Rip off the FC layer by pulling a peek tab. Make sure the ionized N2 is applied during ripping.
- Margot has a Dark Field Microscope. We checked how the dusts are removed from the surface.
There are many dusts on the mirror even if they are invisible. First Contact actually removes
these dusts very efficiently. Margot told us that even carbonhydrates (like finger prints) can be removed by FC.
