Fabricating Big Braces
Today I milled some very large and beefy braces to serve as support for a vertical breadboard I am mounting on the anti-vibration table. Using a 1/20 wave ULE Flat, I will reflect the laser from the Zygo vertically, through test lenses. This will make it easier to optimize our apo triplets by rotating each element and testing which orientation has the highest rating. We just keep pushing the envelope!
