LSST

The LSST monolith primary and tertiary mirror is now annealing in its oven at the University of Arizona Steward Observatory Mirror Lab. High Fire was achieved on March 29th. Scroll down for images of the glass loading or click the links below for a time lapse video of the individually inspected and hand loaded borosilicate glass melting in the casting mold.

	Mirror Glass Loading Progressing Shown here are the initial pieces of E6 glass being loaded into the furnace mold. The loading process will take two days to complete and requires 51.900 pounds of glass. Format: JPG Full version: 4.2 MB. Photo Credit: Ray Bertram / Steward Observatory
	Glass Loading Underway Glass loading for construction of the LSST primary/tertiary mirrors is underway at The University of Arizona's Steward Observatory Mirror Lab. In the foreground two SOML workers open boxes of glass and send them up for placement in the mold. The fellow standing on the platform controls the mold rotation while two workers (partly hidden) place the glass chunks in their proper place. Three pallets of glass in their boxes sit in the background waiting their turn to be loaded. Format: JPG Full version: 740 kB. Photo Credit: Chuck Claver/LSST Corporation
