Cylindrical Lenses

JML is recognized as a leader in the design and manufacturing of cylindrical optics. We have reached this position by acquisition and substantial capital expansion with state-of-the-art equipment.

With some of the best capabilities in the industry JML has leveraged its speed to market and engineering talent to address several rapid turn prototype requests from customers in addition to its existing portfolio of traditional cylinder business.

Why Cylinders?

A cylindrical lens differs from other lenses because it focuses light into a line and not a point, because the lens has a radius of curvature in only one axis. Since cylindrical lenses produce magnification in only one axis, they are used to correct for astigmatism and to produce intentionally anamorphic images.

Cylindrical lenses are often used in medical devices, aerospace and defense, and entertainment industries. By using our experienced engineering group and optical technicians and our depth in manufacturing capabilities, we are able to produce highly engineered cylindrical optics to meet the most demanding performance specifications for our customers.

Manufacturing Our Cylinders

JML uses traditional x-y axis fabrication techniques, combined with more advanced metrology and CNC machines to fabricate highly precision engineered cylindrical lenses.
