2-Axis Adjustable Mount--18 inch

The knobs have a satisfying, precise feel when dialing in alignment on my interferometer setup. It holds my 6-inch reference flat securely without any wobble.

I was worried the 18-inch length would be too short for my setup, but it actually gives me plenty of reach for aligning my reference flat. The knobs have a nice, positive click to them that makes fine-tuning feel really precise.

The two-axis adjustment is buttery smooth and holds position perfectly, even after I've been tweaking it all afternoon. It's a solid, hefty piece that feels like it belongs in a real lab setup, and the 18-inch span gives me room to work without knocking other optics around.
