General Optics
Meniscus Lenses
Get excellent optical performance along with economy using these precision ZnSe meniscus lenses.
Meniscus lenses are the "best form" single-element optic for ZnSe due to its high refractive index. Thus, they offer smaller focused spot sizes than plano-convex lenses yet are less costly than aspheric lenses since they are easier to manufacture.
AR-Coated Meniscus Lens Selection
Choose a standard lens or specify exactly the component you require. Our extensive inventory of test plates and tooling minimizes fabrication costs for custom items.
