Buying Ball Lenses

Ball lenses are lenses having the geometrical form of a ball (sphere), which may be rather small (microoptics). They are used as beam collimators for optical fibers, fiber-to-fiber coupling, and other applications requiring compact and precise optical components.
Making Good Purchase Decisions
As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.
NEW: Structured Decision Process
Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.
Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

![]() 1100 US-22 North Plainfield, NJ 07060 United States See us at LASER World of Photonics 2025 in Munich, June 24–27 (booth B1.171B)! | ![]() A ball lens consists of a highly transparent spherical ball, usually made of solid glass (fused silica) or another optical material with index of refraction less than 2. Most ball lenses are made with small diameters – a few millimeters or even less than a millimeter. The optical physics can be understood by realizing these lenses are, equivalently, two plano-convex lenses separated by a parallel plane. Product-specific web page |
