Specifications:

ARO guarantees every one of our printed specifications because we have the procedures in place throughout fabrication necessary to meet these numbers, and the instrumentation required to test for them. Furthermore, our specifications are not “average” or “typical” numbers; rather, they are minimum specifications that each of our components are manufactured to meet or exceed.

Angle of Incidence

Angle of incidence is defined to be the angle between the direction of propagation of incoming light and a line perpendicular to the component surface. ...

Diameter Tolerances

Dimensional tolerances refer to the allowed variations in the physical dimensions, such as diameter, length, width and thickness, of a finished part. Performing dimensional measurements ...

Extinction Ratio

Extinction Ratio is the ratio of transmitted power with only p polarized incident light to the transmitted power with only s polarized incident light. ARO ...

Dimensional Tolerances

Dimensional tolerances refer to the allowed variations in the physical dimensions, such as diameter, length, width and thickness, of a finished part. Performing dimensional measurements ...

Material

The purity of both substrate and coating materials has a significant impact on the final reflection/transmission and laser damage threshold characteristics of an optical component, ...

Reflectivity

Reflectance is the ratio of the light flux returned from a surface to the amount of light flux incident on the surface. In the context ...

Surface Flatness

For plano parts, surface flatness is defined to be the amount by which the actual part differs from a perfect plane. For radiused parts, two ...

Surface Quality

Surface quality, or scratch and dig (SAD), relates to the number and apparent size of visible defects, typically scratches and pits (called digs), on the ...

Surface Roughness

Surface roughness is the texture of an optical surface on a microscopic scale, as opposed to flatness, power and irregularity which all relate to large ...
