Reversible?
Can optically bonded sections be pulled apart again, or are they stuck permanently?

A quick google search suggests both:

Optical contacting has been used for years in precision optical shops to block optics for polishing because it removes the dimensional uncertainty of wax or adhesives. Because the process is not very robust and can be easily “broken,” parts optically contacted in the traditional manner must be sealed around the edges to prevent breaking the contact.

Today, however, variations on traditional optical contacting can create precise, optically transparent bonds that are robust and mechanically strong (see Fig. 1). These improved processes result in a bond as strong as if the entire structure had been made from a single piece of material, and bonds have even passed Telcordia’s stringent requirements for durability, reliability, and environmental stability. Because these bonds are epoxy-free, they can withstand high optical powers and low temperatures.

I don't have enough knowledge of the topic. Which is it? ElectronicsForDogs (talk) 11:56, 6 March 2023 (UTC)


 * My background here is also limited, but I read that as stating that current capabilities for achieving superb surface finishes and molecularly flat surfaces allows optical contacting to produce bonds similar to or as strong as the original materials' properties.
