12" DWL Transmission Flat, Dynaflect

I was pleasantly surprised by how flat the 12-inch transmission surface is—it made our collimation setup so much easier. The Dynaflect coating held up well even after repeated handling during calibration.

As someone who works with interferometry daily, getting a flat this size that holds its figure across the full aperture is rare. The Dynaflect coating is exactly what I needed for high-reflectance tests, and the 12-inch diameter handled our largest setup without any edge roll-off. Calibration data i

Setup was straightforward, and the 12-inch diameter gave me plenty of working space. The Dynaflect coating really cuts down on stray reflections during alignment.
