Optical components customized to your precise specifications

When you demand absolute precision in optical components, we provide you with the best. Beam Precision Optics Inc. precisely fabricates specialty custom optics for a wide range aerospace, military, medical, instrumentation and control and industrial applications.

We provide lenses, mirrors, windows, prisms, partial reflectors, brewster windows, wedges and beam splitters from any optical raw material in quantities from a single piece to 100,000 depending on size.

Applying the tightest possible quality control standards, we specialize in achieving the accuracies and tolerance you specify… on time and on budget.

And we follow through with the secondary drilling, cutting, slotting and edging you need to meet your design.

Metal Optics

Optical mirrors are fabricated from copper, nickel, stainless steel, aluminum or nickel plate in 12mm to 300mm diameters with gold, aluminum or enhanced silver coatings.

Specifications are held to:
Flatness – 1/80 of a wave at 10.6 microns
Dimensional Tolerances - .5mm
Surface Quality – 60-40
Focal Length Tolerances – 1%

Secondary Operations

The following precision secondary operations can be applied to finish all Beam Precision Optics components:

Drilling holes from .5mm to 50mm diameter.
Cutting to 1mm
Edging to 1mm

All materials except metal can be precision slotted to 1mm recesses.

Visible Spectrum Optics

Components for the visible spectrum are produced as lenses, prisms, front surfaces mirrors, windows, wedges and optical flats with diameters from 12mm to 300mm and coatings that include ALSIO, MGFL, gold and enhanced silver.

They are fabricated from quartz, pyrex and BK-7.

Specifications are held to:
Flatness – 1/20 of a wave
Parallelism – .5 second
Surface Quality – 10-5
Optical Centering - .025mm
Dimensional Tolerances - .1mm
Focal Length Tolerances – 1%
Mirrors Spherical – 1/20 of a wave
Prisms Angular Tolerances – .5 arc seconds

Infrared Optics

Components for the infrared spectrum are fabricated as lenses, beam splitters, prisms, wedges, windows and brewster windows from 12mm to 200mmm diameters and with custom coatings that include AR, partial reflective, non-polarizing, beam splitters and gold.

They can be made from zinc selenide, zinc sulfide, metal optics, germanium and silicon.

Specifications are held to:

Flatness – 1/80 of a wave at 10.6 microns
Parallelism – 30 seconds arc
Surface Quality – 40-20
Optical Centering - .025mm
Dimensional Tolerances - .1mm
Focal Length Tolerances – 1%
Angular Tolerances – 1 arc minute
