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 N-BK7 Optical Glass or equivalent glass*. Indicate in order notes if N-BK7 is required. Every optic is pitch polished, providing superior 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 custom lens please use our online fast online quote tool.

Customer Reviews (4.6 / 5 · 5 reviews)

John L. ★★★★★

These arrived well-packaged and the optical clarity is genuinely impressive for the price. I'm using them to collimate a laser beam and the focal length is spot-on for the parallel light work I needed.

Andrew ★★★★★

The transmission on these is noticeably cleaner than the cheap uncoated lenses I was using before. I'm focusing a collimated diode down to a tight spot and the spherical surface gives me a clean, round focus with no visible scatter. Great value for N-BK7 at this price.

Nicholas I. ★★★★★

The edge is nicely beveled and the N-BK7 glass arrived completely free of chips or sleeks, which is more than I can say for my last order elsewhere. Collimating a laser with these was dead simple since the flat back sits flush against my mount.
