كرة إرسال 2 بوصة 10.6 ميكرومتر - f/1.5

I needed a reference sphere for aligning my CO₂ interferometer, and the 1/20th wave PVr specification at 10.6 µm gave me confidence it would deliver. It definitely tightened up my measurement repeatability.

The f/1.5 aperture on this transmission sphere works perfectly for our CO2 laser setup, and the 1/20th wave PVr specification at 10.6 µm is dead-on accurate. The only minor downside is that it’s a bit finicky to align initially, but once dialed in, the beam quality is exceptional.

Built solid, but it's a niche tool—you're not reaching f/1.5 unless your setup is dialed in perfectly. The 1/20th wave accuracy is great for testing, but I wish the mounting threads felt less delicate.
