Photonics Dictionary: C

A lens aberration in which the focal length varies radially outward from the center of the field. It has the effect of making a straight tangential line in the object appear curved in the image,...

Custom lapping and polishing services involve specialized processes used to improve the surface finish and dimensional accuracy of components to meet specific requirements or standards. These...

A custom optic refers to an optical component that is designed, manufactured, and tailored to meet specific requirements or applications. These optics can include lenses, mirrors, prisms, filters, or...

A technique for measuring fiber attenuation or distortion by performing two transmission measurements. One is at the output end of the full length of the fiber. The other is within 1 to 3 m of the...

The process of forming a lens to a given pattern, or of cutting a piece of glass along the line of scratch.

The tendency of charge carriers to spiral about an axis in a direction identical to that of an applied magnetic field that has an angular frequency formed by the value of the applied field and the...

A cylindrical lens is an optical component that has different curvatures along its two orthogonal axes, resulting in a shape resembling a cylinder. Unlike spherical lenses, which have the same...

An endoscope used for the visual examination of the bladder.

A form of monochromator optical system consisting of two spherical concave mirrors used in conjunction with a movable diffraction grating.

Popular process for silicon and polycrystalline production that consists of an alteration of the original state of a substance; thus, single-crystal materials can be used to form a polycrystal.
