This is a 20mm diameter 4″ (101.6mm) focal length Meniscus lens for the 4″ Nova series heads and any other 4″ head that accepts ZnSe 20mm diameter focal point lenses.

Meniscus lenses are designed to minimize spherical aberration producing a minimum focal spot size for incoming collimated light. Unlike the plano-convex lenses normally used in most CO2 gantry machines, these lenses are ground on both faces so its actually a compound optic.

II-VI Infrared is the world leader in laser optics, delivering an unbeatable combination of innovation, quality, and expertise.
