Photonics Dictionary: L

An erecting prism that inverts and reverses the image. It displaces the optical axis but does not deviate it.

A small half-shade analyzer placed in the eyepiece of a polarimeter to determine the character of the polarized light emitted by the instrument. It consists of a Nicol prism situated so that it...

A 30-60-90° spectrograph prism that is coated on the surface opposite the 60° angle with a reflecting film.

A dark band that may appear in the field of crossed Nicol prisms with a powerful source such as the sun because the light is not strictly parallel and is not extinguished immediately.

Laser optics refers to a broad category of optical components and systems designed for manipulating and controlling laser light. Laser optics play a crucial role in shaping the characteristics of...

The process whereby white light is separated into its component wavelengths. Light beams of different wavelengths are separated from each other by undergoing a different angular deviation. Prisms and...

Linear optics refers to the study and manipulation of light in a linear and deterministic manner, where the response of optical elements is proportional to the amplitude of the incident light wave....

A spectrograph using a prism that has an internally reflecting surface and that serves as a constant deviation prism.

A photometric instrument having two prisms clamped in optical contact to produce a photometric field with an acute dividing line.
