SUMMARY

The discussion centers on the intricate and time-consuming process of creating giant telescope mirrors, specifically referencing the University of Arizona's Mirror Lab. The polishing phase is highlighted as a critical and delicate step, requiring precision akin to the "wax on, wax off" technique popularized in skill development. The conversation also touches on the physical properties of molten glass during shaping, though terminology confusion occurred regarding "rigor mortis." Additionally, robotic polishing technology is mentioned as an example of achieving high reflectivity, analogous to telescope mirror finishing.

PREREQUISITES

  • Understanding of optical glass melting and shaping techniques
  • Knowledge of precision polishing methods for telescope mirrors
  • Familiarity with robotic polishing technologies
  • Basic concepts of material science related to glass behavior during cooling

NEXT STEPS

  • Study the University of Arizona Mirror Lab's specific polishing protocols
  • Research advanced robotic polishing systems used in optical manufacturing
  • Explore material science principles governing molten glass solidification
  • Investigate surface reflectivity measurement techniques for telescope mirrors

USEFUL FOR

Optical engineers, astronomers involved in telescope construction, materials scientists specializing in glass, and manufacturing engineers focused on precision polishing and robotic automation.

I saw the mirror lab at the University of Arizona when I was enrolled there. Very cool!
 
A delicate process that's for sure!

I couldn't help but thinking ligor mortis in telescope melted glass terms. If that makes any sense, which I actually doubt! o0)

EDIT: Well, I actually didn't mean "rigor mortis" but the post-mortem state of a body where the blood sinks to the bottom of the corpse. I thought it was called "ligor mortis" but searching for it now I come up empty.

During the polishing scene I couldn't help but thinking wax on, wax off.

In Bangkok's Don Mueng airport is a corridor. The floor is polished by a robot. Shiniest floor you ever saw, reflects the lights like a son of a gun.
