Photonics Dictionary: B

A beam shaper is an optical device or system designed to modify the spatial profile or intensity distribution of a laser or light beam. The goal is to transform the incoming beam into a desired shape...

A convex, concave or flat cast iron form that is used to shape a soft mold block of optical components.

The negative distortion that causes a square grid pattern to be imaged as barrel-shaped.

The roughness profile shape from which light scattering is expected to occur.

A device used to alter the shape of or energy distribution within a beam of radiation.

Beam profiling is a technique used to characterize and analyze the spatial intensity distribution of a laser beam. It involves measuring and visualizing how the optical power or intensity is...

A type of fiber optic connector consisting of two cone-shaped ferrules aligned by a mating sleeve.

Combining adjacent pixels into one larger pixel, resulting in increased sensitivity and lower resolution, or, in image analysis, excluding objects based on shape, position or area.

A piece of glass, quartz or other transparent material formed roughly by molding or cutting into the approximate shape and size of the finished part.

An extended bubble or seed on glass, elliptically shaped and more than one-quarter inch (6.3 mm) in length.

An adhesive used to affix optical elements to an approximately shaped body -- usually of cast iron.

A blur circle refers to the out-of-focus region in an image captured by an optical system. When an object in a scene is not in perfect focus, its image is spread out into a circular shape on the...

The simplest, most inexpensive type of camera, which is shaped as an oblong or square box, containing the simplest lens, shutter and viewfinder, as well as the most elementary means of registering...

An electric filter that is characterized by a passband of the flattest possible shape.
