Confocal conic sections

In geometry, two conic sections are called confocal if they have the same foci.

See Confocal and Confocal conic sections

Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser scanning confocal microscopy (LSCM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation.

Conic section

A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane.

See Confocal and Conic section

Ellipse

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.

See Confocal and Ellipse

Focus (geometry)

In geometry, focuses or foci (focus) are special points with reference to which any of a variety of curves is constructed.

Focus (optics)

In geometrical optics, a focus, also called an image point, is a point where light rays originating from a point on the object converge.

Geometry

Geometry is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures.

Hyperbola

In mathematics, a hyperbola is a type of smooth curve lying in a plane, defined by its geometric properties or by equations for which it is the solution set.

Lens

A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.

See Confocal and Lens

Optics

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

Perpendicular

In geometry, two geometric objects are perpendicular if their intersection forms right angles (angles that are 90 degrees or π/2 radians wide) at the point of intersection called a foot.
