Biconvex lenses have two convex spherical surfaces, typically with the same radius of curvature. Knight Optical offers stock and custom biconvex lenses, available uncoated or with anti-reflective coatings for visible to NIR applications.These versatile lenses are used for laser beam focusing and control, moderate-quality imaging, and optical instruments.
Knight Optical can provide custom optics or can edge stock lenses for quick turnaround.
Each component is individually tested in our advanced metrology lab to ensure high quality. Contact our technical sales team to enhance your instrumentation and supply chain experience.
