Polarizers

ARO thin film polarizers deliver an unmatched combination of high extinction ratio, high damage threshold, excellent mechanical durability and long operational lifetime. The technology employed to fabricate these high performance polarizers has evolved from our collaborative experience in producing optics for some of the world’s most demanding laser systems and applications. These include the world’s largest laser system (at the Lawrence Livermore National Laboratory National Ignition Facility) and beam path optics for cutting edge, ultrafast laser-based research.

From substrate preparation to thin film coating and product packaging, we apply our state-of-the-art expertise to both stock and custom built optics.

Made to order
Custom Polarizers

Our technical team will review your optical drawing or custom specifications and provide a quote.   Typically we offer:

Surface quality: 10/5  Laser Quality (scratch/dig)
Surface flatness: we routinely provide 1/10λ Peak to Valley at 632.8nm, with the ability to achieve 1/20λ Peak to Valley
Standard tolerances include +0/-0.005″ for diameter, length or width and ± 0.005″ for thickness
Parallelism: 1 minute
(alternate specifications/tolerances available upon request)

Excimer
UV Polarizers

These high performance, thin film polarizers are first surface coated to separate orthogonal polarizations with a high extinction ratio; the second surface is uncoated. They are available from stock at most common UV solid state laser wavelengths. They are designed to work at Brewster’s angle, and should be tilt tuned (±3°) to optimize performance.

ARO’s extensive experience in supplying optics for demanding solid state laser applications, such as National Ignition Facility at Lawrence Livermore National Laboratory, has enabled us to develop these polarizers with an optimum combination of high extinction ratio, laser damage resistance and mechanical durability, even at short UV wavelengths. In addition to these stock components, ARO can readily produce polarizers customized in virtually every aspect, including size, shape, substrate material, surface specifications and performance characteristics.

Ultrafast
TI:SAPPHIRE POLARIZERS

These high performance, thin film polarizers are coated to separate orthogonal polarizations with a high extinction ratio. They are designed for use over a broad spectral bandwidth centered on 800 nm. They are intended to be used at Brewster’s angle, and should be tilt tuned (±3°) to optimize performance.

Close cooperation between the ARO design staff and leading ultrafast researchers has enabled us develop to these polarizers with an optimum combination of high extinction ratio, spectral bandwidth, laser damage resistance and minimal group velocity dispersion. In addition to these stock components, ARO can readily produce polarizers customized in virtually every aspect, including size, shape, substrate material, surface specifications and performance characteristics.
