雙凸鏡片，G1 商業級熔融石英

I needed a lens for a narrow-spectrum imaging setup, and the G1 fused quartz material delivers exactly the clarity I was hoping for. The beveled edges made mounting it in my holder much smoother than with other optics I've tried.

The fine-ground, beveled edges on these G1 fused quartz lenses made mounting them in my setup much smoother than I expected—no chipping or scratching during handling. They’ve given me clean, crisp imaging for my finite conjugate test rig right out of the box.

Been using these for finite conjugate imaging in a narrow spectral range and they hold focus really well. The G1 fused quartz is clean, and the beveled edges make mounting them a lot less nerve-wracking.
