Plano-Convex Lenses, Plano Convex Lenses

Plano-convex lenses are positive focal length elements with 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 optics are ideal for general purpose focusing elements.
Our lenses are ideal for a variety of applications, from industrial,
robotics, pharmaceutical to defense.
Esco manufactures plano-convex lenses using S1-UV grade fused silica, G1
fused silica, commercial grade and BK7 optical glass. Each optic is pitch
polished to provide good surface quality and excellent low-cost imaging
performance for a wide range of light sources.
When plano convex lenses are used for laser cutting, they are best suited
for high-turnover cutting applications and when cutting thick materials. In
these cases, the plano-convex lens provides a larger cut width, which allows
the laser's oxygen-assisted access to cut and aid in the cut. Plano convex
lenses also provide greater depth of field, which helps create tapered
edges.
