مرآة بوروفلوت 33، أقصى انعكاس 532 نانومتر

Finally, a mirror that doesn't eat my beam energy—the 532 nm coating reflects almost everything. My laser alignment has been rock solid since swapping it in.

I was losing a noticeable amount of power with my previous mirror, so I tried this narrowband one for my 532 nm setup. The Max R coating really does reflect almost everything at that wavelength — my beam stays tight and the spot barely heats up at all.

Swapped out my old broadband mirror for this narrowband one and the difference in beam brightness at 532 nm is obvious immediately. The Max R coating barely warms up even after long runs, which tells me it's absorbing almost nothing. Exactly what I needed for my setup.
