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 during part fabrication is usually relatively straightforward, and is accomplished using familiar tools such as calipers, gauges and optical comparators.

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 determines extinction ratio by performing separate measurements of s and p polarized light transmittance in our spectrophotometers.

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 of precision optical components, the returned light flux specifically refers to specular reflectance (energy contained within the usable returned wavefront), and does not include diffuse reflectance (scattered light).

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 part surface. While this may seem straightforward, probably no optical specification causes greater confusion.

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 numbers are typically used to specify surface shape.

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 scale (macroscopic) surface shape. Surface roughness, which can be defined a number of different ways (arithmetic average, root mean square, etc.)
