Plano-Convex Lens with Outer Diameter 6.9mm
A plano-convex lens has one flat and one spherical convex surface and positive focal length. It focuses parallel beams and collimates divergent point-source light. The stated orientation places the flat side toward parallel light or an object at infinity and the convex side toward the focus/image plane, greatly reducing spherical aberration and astigmatism and improving beam-transmission uniformity and accuracy. A 6.9mm outer diameter is a small-to-medium precision size with easier clamping/assembly than miniature lenses. CA is generally ≥6.2mm, stated as over 90% of diameter. A standard protective chamfer <0.2mm×45° prevents chipping/scratching during clamping, cleaning and assembly, suiting compact small-to-medium optical modules. 南京领英创光电科技有限公司 offers customization to requirements and welcomes inquiries.
