Spherical Lenses - Product Page

Precision Optical Lenses

PFG spherical lenses deliver the performance that today’s most advanced optical systems demand. Engineered for excellence in applications such as defense, aerospace, and imaging, every lens is produced in our fully integrated U.S. facility, where fabrication, metrology, coating, and assembly come together under one roof for total process control.

Custom Lens Applications

Custom precision optical lenses are essential components in imaging, sensing, laser systems, and much more across the photonics landscape. Designed to focus, collimate, or otherwise shape light with exceptional accuracy, spherical lenses are fundamental to many optical systems.

Unlike catalog optics, custom lenses are built to your exact specifications, including material, coating, and geometric needs. This ensures optimal performance, seamless system integration, and consistent quality. Custom lenses also allow for Design-for-Manufacturing (DFM) optimization as well as supply chain resilience.

Custom Lens Configurations

PFG specializes in manufacturing precision optical components in a range of geometries, supporting a broad range of materials from ultraviolet to mid-wave infrared (MWIR) applications. Here are some of the most common lens configurations:

Plano-Convex / Concave Lens

Plano-Convex/Concave lenses have one spherical side and one flat (plano) side. This geometry is generally cost-effective as flat sides are less expensive to manufacture.

Bi-Convex / Concave Lens

Bi-Convex/Concave lenses have two spherical surfaces and are generally used as part of a set of lenses in an imaging application.

Meniscus Lens

Meniscus lenses have one convex and one concave side. They can have overall positive or negative power, depending on the radii chosen.

Infrared (IR) Lens

Infrared lenses operate in the IR wavelengths. Many of these lenses are made from crystalline materials, such as Silicon, Germanium, Calcium Fluoride, or Zinc Selenide.

Ultraviolet (UV) Lens

Ultraviolet applications require low scatter, smooth surfaces and are typically made from Calcium Fluoride (CaF₂) or Fused Silica materials. UV optics are common in the semiconductor, defense, and imaging sectors. Surface roughness and mid-spatial frequency (MSF) errors are critical to performance.

Large Diameter Lens

Large lenses are lenses exceeding 150mm in diameter. Special manufacturing processes for large optics include CNC or pitch polishing as well as large aperture metrology. PFG's large optics are ideal for high-energy laser systems, telescopes, beam expanders, and imaging assemblies.
