Cube Beamsplitters - IR
REO offers cubes with a mix of narrow or broad bandwidth operation throughout the IR. These precision cubes provide high laser damage threshold, high transmission ( >95% ) and high extinction ratios ( >100,000:1 ). Custom cubes utilizing our proprietary adhesive free bonding technique are available in the 1 mm to 75 mm size range with LDT that is only limited by the bulk material.

All cubes are contacted with our proprietary adhesive-free Activated Covalent Bonding process.
Activated Covalent Bonding
Activated Covalent Bonding (ACB) technology, REO’s proprietary adhesive-free method of bonding optical components, can be used to produce a wide array of monolithic visible and IR optical assemblies, such as cube beamsplitters, x-cubes, and beam combiners and separators. ACB delivers bond strength matching that of the bulk material, but unlike traditional gluing, introduces essentially no wavefront distortion, minimizes scatter and absorption. This bonding approach substantially improves component laser damage resistance and operational lifetime. It can also be used for applications at wavelengths where adhesives are not transmission.

Thin Film Coating
Over 20 years ago, REO became the first company to commercially provide Ion Beam Sputtered (IBS) thin film coatings. Today, we have expanded our technology to produce the highest quality thin films performing a range of functions across the full optical spectrum from the deep UV (190nm) through the long wave IR (14um). With a total of 35 coating chambers in operation, REO’s ability to produce the highest performance, lowest loss, most durable thin films across the spectrum is unmatched in the world.
