Borofloat 33 Mirror, MAX R 532 nm

$45.94 ~~$63.8~~ In stock

Narrowband Maximum Reflecting Coating (MAX R) Typically used with lasers, Max R coatings provide nearly complete reflection over a specific spectral range, absorbing negligible incident energy. These high-purity coatings are very durable--designed to meet all standard MIL requirements. The trade-offs for high reflectivity (compared to metal reflectors) are: increased polarization sensitivity and increased cost.

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.

Benjamin ★★★★★ Oct 13, 2026

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.

Claire P. ★★★★★ Oct 12, 2026

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.
