Optical Polarizer

ARO offers optical polarizers with narrow and broadband options. Our coatings have high damage thresholds and high extinction ratios with S or P pol optimization capabilities.

Product Selection

UV Polarization

ARO’s catalog UV polarizers are a great low-cost option for your laser application. In addition to catalog options, we provided modified stock and custom UV polarizers down to 193 nm.


Ultrafast Polarizers

ARO offers thin film polarizers that have been designed to provide the top performance in Ti:Sapphire amplifiers. Multiple round trips in the amplifier have a multiplying effect on the characteristics of any optic in the cavity. The ARO sales team can offer a free quote for custom thin film polarizers.


High Energy Polarizers

ARO achieves high-energy polarizers performance through advanced coating design and superior technology. Polarization optics are made for use in some of the most demanding lasers in the world. ARO’s polarizer coatings are great for use with Nd:YAG lasers.

Plate and Cube Beamsplitters

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. ARO supplies polarizers for 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 universities.

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. Alpine Research Optics provides a wide selection of the highest quality polarizers for laser systems.

Polorizing Beam Splitters

Polarizing beam splitters are used to separate light into polarized parts. They often find their application in photonic devices for the transmission of p-polarized light while reflecting s-polarized light. We offer a wide range of polarizing beam splitters in a variety of shapes and configurations to suit a wide variety of applications, be it splitting the incident beam into two offset parallel beams or splitters that are designed for conventional wavelengths. We are committed to providing you with a choice of polarizing beam splitters designed with the latest technology to represent Alpine Research Optics’ quality assurance policy.

Optical Polorizers Manufacturing

We employ only the most professional workers who have been manufacturing, fabricating, and coating polarizers for years. Regardless of what form of polarizing optics you may need, we will provide you with only the best options. We handle the complete process of creating, assembling, and processing any polarizing mirrors, windows, lenses, beam splitter and more. Our optical products are always of the highest standard, which is why our polarizing optics are used by an extremely wide range of customers in a diverse range of fields.
