SED Machine Bonding Woes

The bond of achromatic doublet cam1/cam2 went down without a hitch. Cam 1 is a CaF2 element and Cam2 is an i-line glass from Ohara. The bond with Sylgard-184 looks clean.

Camera 1/2

Camera 1/2 doublet - a success. Cam 1/2 was bonded three days ago, and it will cure for about three more days before it will be installed in the lens barrel.

Today Marin Anderson and I planned to bond collimator 1 and 2. Unfortunately, collimator 1 is AR coated on both sides. I've put a call into the vendor and need more information to proceed.
