Notes:
We have constructed an optical cell with CaF2 windows which are sealed with metal C rings. We have demonstrated vacuum leak rates for He of less than ∼10−9 std atm cc/s between 20 and 110 °C, as well as pressure cycling between ∼10−4 Pa and ∼5 MPa. This seal is useful where outgassing or permeability of elastomeric O rings would present problems.
