Eva ★★★★★

The lambda/25 PVr spec on this 18-inch flat is spot-on—it cleaned up our interferometer alignment in one shot. The 4% reflectivity makes it ideal for low-coherence setups without ghosting issues.

Aurora ★★★★★

Took a chance on this 18-inch flat for some critical alignment work, and the lambda/25 PVr figure is no joke—the surface quality is genuinely excellent. It's a solid piece of glass that performs exactly as specified.

Hannah ★★★★★

I was worried the 4% reflectivity would be too faint for my setup, but it's actually perfect for the interferometer work I'm doing. The lambda/25 PVr figure holds up when I check it against my reference. Solid piece of glass, no complaints.
