مرايا مسطحة عالية الدقة، ألمنيوم محسّن

These arrived perfectly packaged and the coating is noticeably cleaner than cheaper options I’ve tried. The 50.8mm fused silica substrate feels substantial and works great in my setup.

I needed a mirror that could handle both visible and near-IR wavelengths, and the 90%+ average reflectivity from 450 to 2000nm is spot on for my setup. The 12.7mm Borofloat substrate feels solid and holds alignment perfectly without any warping.

Picked up the 25.4mm fused silica version for a beam-steering setup and the surface flatness is dead-on across the whole aperture. Reflectivity holds up noticeably better than my old mirrors past 1500nm, which is exactly where I needed the extra headroom. Zero complaints so far.
