PRECISION LENSES AND OPTICAL COMPONENTS
PRECISION LENSES
Extensive lens manufacturing capabilities using all types of materials and processes. We select the best process technology to produce the required specifications. This allows us to achieve the required optical performance desired from a given material. Our best practices have been developed from decades-long experience to achieve timely and efficient production.
LENSES
PFG has extensive lens manufacturing capabilities using all types of optical glasses, fused silica and crystalline materials including CaF2, Ge, MgF2, Si, ZnSe, ZnS and Amtir. We select the best process technology from spindle polishers, CNC polishers, magneto rheological finishing or a combination thereof to produce the required specifications – some subtle such as low spatial frequency, some more obviously beneficial such as low surface roughness – to achieve the required optical performance from a given material.
Tight centering, truncation, high included angle or long radii – we use best practices developed from decades-long experience to achieve timely and efficient production. We have a vast library of test plates and many current model Zygo interferometers, all with complete reference spheres for accurate surface measurement.
OPTICAL FLATS
High performance mirrors, windows, and wedges in a wide variety of shapes, sizes, and materials. Our technicians are comfortable working with 100+ optical glasses, fused silica, and crystalline substrate materials. Selecting the optimal process technology and adhesion/blocking method allows us to quickly and efficiently produce optical flats to the most demanding specifications.
OPTICAL FLATS
PFG delivers high performance mirrors, windows and wedges in a wide variety of shapes, sizes and materials. We are accustomed to working with most all optical glasses (100+), fused silica and crystalline substrate materials such as CaF2, Ge, MgF2, Si, ZnSe, ZnS and Amtir. Our technicians are able to produce optical flats to the most demanding specifications for flatness, transmitted wavefront, parallelism (angular tolerances on wedges) and surface cosmetics.
Whether using continuous polishers or double-side polishers, we confidently select the optimal process technology, and adhesion and blocking method (pitch, tape/wax or optical contacting) to meet your specifications. Our polishing technicians clearly understand that substrate type, dimensions, blocking method and material, final shaping, aspect ratio and coating, all significantly impact the end result. For wedged optics we have an extensive inventory of tooling, in many instances allowing us to avoid tooling charges and to reduce delivery times to our customers.
Coatings range from the deep ultraviolet through the mid-wave infrared. We provide dielectric and metallic mirrors; as well as notch, edge, dichroic, color substrate and neutral density filters.
PRISMS
Made to fit stringent specifications for angle, flatness, transmitted wavefront, dimension, clear aperture, surface quality and sharp rook. Current capabilities include: right angle, boresight, delta, porro, pechan, risley, and dove prisms; pentaprisms; corner cubes; and rhomboids. We possess the technology, tooling, ingenuity, and metrology to consistently deliver superior performing prismatic objects.

We possess the process technology, tooling, know-how and metrology to consistently deliver superior performing prismatic optics. Substrate material very familiar to us include most all optical glasses, fused silica, Si, ZnSe, ZnS, CaF2, MgF2 and Cleartran.
BEAMSPLITTERS
Extensive selection of tight-tolerance plate and cube, typically polarizing beamsplitters from UV to MWIR. PFG offers an extensive variety of plate and cemented beamsplitters from UV to MWIR in a wide selection of sizes and glass types. Ranging from neutral density to dichroic to bandpass, including both polarizing and non-polarizing, PFG can customize these beamsplitters to meet your specific application. These beamsplitters can be applied to right-angle prisms, wedge prisms, penta-prisms, or rhomboids and may be optically cemented or chemically contacted for improved laser damage threshold.
BEAMSPLITTERS
PFG produces a wide variety of custom thin film polarizers in the UV, visible, and MWIR to meet your specific need. Our laser line polarizers combine high extinction ratio and high damage threshold for use in laser applications. These polarizers exhibit up to 10,000:1 extinction ratio and greater than 98% transmission for P-polarization. Our high damage threshold and excellent mechanical durability provide long operational lifetimes. Our polarizing cubes can be used for laser line or broadband applications. These cubes can be custom designed to meet a range of applications and provide high extinction ratios over a broad range, and can be cemented or chemically contacted for improved laser damage threshold.

POLARIZERS
Thin film cube or plate polarizers that deliver an impressive combination of qualities. PFG has stringent polishing and coating process parameters that ensure high quality polarizers. We can match high extinction ratio, high damage threshold, low loss, excellent mechanical durability, and long operational lifetime. Capabilties include: ultraviolet, visible, and mid-wave IR wavelengths with many split ratios.
