What's the most unusual way you've seen an optical component fail?

Scratched coatings?

Thermal shock?

Chemical attack?

Unexpected contamination?

Every engineer has at least one story.

We'll start: many industrial windows fail because the material wasn't selected for the actual operating environment.

What's the harshest environment your optics have ever had to survive?

High temperatures? Abrasive particulates? Corrosive chemicals? Extreme pressure?

At Meller Optics, we manufacture sapphire windows and optics for applications where conventional materials simply won't last.

We're curious: What environmental challenge has been the biggest obstacle in your optical system design?
