Absorption (electromagnetic radiation)
In physics, absorption of electromagnetic radiation is the way in which the energy of a photon is taken up by matter, typically the electrons of an atom.

Dispersion (optics)
In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency.

Folded optics
Folded optics is an optical system in which the beam is bent in a way to make the optical path much longer than the size of the system.

Frosted glass
Frosted glass is produced by the sandblasting or acid etching of clear sheet glass.

Lens (optics)
A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.
New!!: Optical path and Lens (optics) · See more »
Mirror
A mirror is an object that reflects light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original light, called specular reflection.

Opacity (optics)
Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light.

Optical filter
An optical filter is a device that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either dyed in the bulk or have interference coatings.

Optical path length
In optics, optical path length (OPL) or optical distance is the product of the geometric length of the path light follows through the system, and the index of refraction of the medium through which it propagates(OP.

Optics
Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it.

Prism
In optics, a prism is a transparent optical element with flat, polished surfaces that refract light.

Reflection (physics)
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.
New!!: Optical path and Reflection (physics) · See more »
Refraction
Refraction is the change in direction of wave propagation due to a change in its transmission medium.
New!!: Optical path and Refraction · See more »
Refractive index
In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how light propagates through that medium.
New!!: Optical path and Refractive index · See more »
Total internal reflection
Total internal reflection is the phenomenon which occurs when a propagated wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface.
New!!: Optical path and Total internal reflection · See more »
Transparency and translucency
In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without being scattered.
