Convex lenses (commercial grade)

What are you looking for in Stock?

Convex lenses are either planoconvex or biconvex in form and generate a positive focal length. Convex lenses come in a very broad range of materials and dimensions to suit a great many applications. Knight Optical’s commercial grade convex lenses are ideal for teaching and experimental work where the higher quality of more expensive precision lenses is not a priority.

Knight Optical offers a very wide range of stock and bespoke convex lenses to suit. We typically supply the components uncoated in B270 glass. Knight Optical can edge down existing stock optics for a fast turnaround where needed, and supply lenses in various materials where an alternative refractive index might be required to obtain the desired focal length within limited dimensions.

Every component is individually tested by our highly skilled technicians in our state of the art metrology lab to ensure all components meet our high quality standards. Please contact our multilingual technical sales team and discover how Knight Optical’s commercial grade convex lenses can improve your instrumentation and supply chain experience.
