PLANO CONVEX FOCUSING LENSES

These low absorption ZnSe positive focusing lenses provide an extended lifetime in laser cutting applications where depth of field is an important factor. Ideally suited for welding, cutting and heat treating, these low cost lenses have superior thermal characteristics which can prevent thermal runaway in high power CO2 lasers.

All series LX lenses are coated and optimized for use at 10.6 microns.
