24 Inch 4% Transmission Flat

It was heavier than I expected, but that just makes it feel more solid on the optical table. The 24-inch diameter covers our large beams perfectly, and the 4% reflection is spot-on for alignment work.

Used it to check a collimated beam setup and the 24-inch aperture handled the whole footprint without any clipping. The 4% reflection is exactly what I needed for low-loss monitoring, and the surface quality held up well under inspection.

The 24-inch diameter is exactly what my setup needed, and the surface arrived clean with no scratches. I've only had it a couple weeks but it's holding its flatness well so far.
