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.

Material selection: optical glass, laser crystal, fused silica, anti-radiation glass, infrared and ultraviolet materials, metal materials
