Plano Convex Lenses


Shanghai Optics, Inc. produces high quality Plano-Convex lenses out of many variations of optical glass and fused silica, and advanced coatings such as anti-reflection or V-coatings can be applied to these spherical lenses to provide added performance. Plano-Convex lenses are commonly used for converging light to a focal point or even for collimating light for applications such as imaging systems, detectors, telescopes and collimators.
Our manufacturing facility produces lenses with an outer diameter as small as 2.3mm and extending up to sizes of 1000mm. The material selection process first begins with transmission requirements, and then other factors such as purity, bubble levels and uniformity will be taken into consideration.
