Largest Corrector Lens C1

c1To the left is a photograph of our largest corrector lens, C1, measuring 1.15m in diameter.  The homogeneity of the fused silca glass came in at an astounding 1ppm (exceeding our 3ppm spec.).  C1 and C4 are about to be packed up and shipped from Corning to L3-Brashear.  L3-Brashear was recently selected to polish C1 and C4.  Arizona Optical Sciences is already at work polishing C2 and C3.  We expect all four of these lenses to be completed through polishing by the end of 2015.
