Plano-Convex Lenses

Plano-convex lenses are positive focal length elements that have one spherical surface and one flat surface. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. These optic lenses are ideal for all-purpose focusing elements.

Esco manufactures Plano-convex lenses from S1-UV Grade Fused Silica, G1 Fused Quartz, Commercial Grade, and BK7 Optical Glass. Every optic is pitch polished, providing good surface quality and an exceptional low-cost imaging performance with a variety of light sources.

We also offer plano-concave lenses, which have negative focal length components and one concave surface. For information on our optic lens custom work, contact Esco today.
