Crescent Focusing Lens

Excellent optical performance and economy can be achieved with ZnSe precision crescent Focusing Lens. Crescent Focusing Lens are the "best form" single optical element of ZnSe due to their high refractive index. They focus smaller spot sizes than plano-convex lenses but cost less than aspheric lenses because they are easier to manufacture.

Features:

1. Using imported ZnSe material

2. Suitable for various specifications of CO2 cutting machines, engraving machines, welding machines and other equipment;

3. The focus spot pattern is smaller and rounder, meeting the requirements of fine processing;

4. Some lenses have dual-band anti-reflection of 650nm and 10.6μm;
