Do other optics suppliers think you’re weird for wanting large lenses? We don’t.

As more and more optical suppliers consolidate and streamline their businesses, few continue to carry large diameter lenses. This is problematic because large diameter optics remain critical for precision instruments such as telescopes and imagers.  

Ross Optical specializes in these kinds of hard-to-find optical elements, including lenses with diameters 6 inches and greater! For example, a customer in the machine vision industry needed a 250mm diameter lens for a condenser system. They had found a 200mm diameter lens from a competitor, but thanks to our reliable global network of optical manufacturers, Ross could provide the exact plano-convex singlet.

Are you making a projector, spotlight, enlarger, magnifier, telescope, collimator, or condenser? What about a custom objective? An eye loupe? Call us and talk to one of our friendly optical engineers. We’d love to help!

Below is a sample of the large achromats and plano convex lenses we can provide. Visit our optics catalog for more options. *Update: We've created a new catalog page with all of our large lenses in one place!

If your project requires parts that we don’t carry, we can create a custom lens or assembly to meet your needs. Once we’ve found the large component you need, we can also perform custom optical coatings, including anti-reflection, V-coating, Rmax, and beam splitters.
