N-BK7 Convex Spherical Lens

Overview:

Plano-Convex (PCX) Lenses have a positive focal length, can focus a collimated beam or collimate light from a point source, making them ideal for collecting and focusing light in imaging applications. Star Optic provides Plano-Convex Lenses fabricated from RoHS-compliant N-BK7, UV fused silica, N-SF11, CaF2, Si, Ge, ZnSe and Sapphire. Our Plano-Convex Lenses are also used in applications involving emitters, detectors, lasers, and fiber optics.
