Plano Concave Lens
A plano-concave lens is an optical lens with one concave and one flat surface. It has a negative focal length and can be used for light projection, beam expansion or to increase the focal length of an optical system.
Plano concave lens bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length. The spherical aberration of the plano concave lenses is negative and can be used to balance aberrations created by other lenses. Similar to the plano concave lens, the curvature surface usually faces the largest object distance or the infinite conjugate to minimize spherical aberration.
Applications
1. Plano-concave lenses are commonly used to divert parallel beams in instruments such as Galilean beam expanders or telescopes.
2. Plano-concave lenses are also used for beam expansion of high peak power pulsed lasers. The incident beam will be focused on a concave surface to a point outside the instrument.
Uses of Optical Prisms
Dispersion: Prisms can be used to separate white light into various colors, a process known as dispersion. When light is refracted through a prism, rainbow colors can be seen, and this is the principle behind the rainbow colors.
Reflecting and redirecting light: Prisms can be used to reflect and redirect light, making them useful in optical systems such as telescopes, cameras and binoculars.
Measuring Angles: Prisms can be used to measure angles by reflecting a laser beam onto a scale or detector.
Beam Control: Prisms can be used to control laser beams in aerospace, medical and industrial applications.
Polarization: Prisms can be used to separate light into its polarized state, which is useful in applications such as LCD displays, 3D glasses and polarization measurements.
Imaging: Prisms are used to create images such as in periscopes, microscopes and endoscopes.
Optical assemblies: Prisms can be used in combination with other optical elements and mechanical parts to create optical assemblies for a variety of applications.
Interferometry: Prisms are used to split a laser beam into two or more beams, which can later be recombined to analyze the resulting interference pattern. Overall, the versatility of prisms allows them to be used in a wide range of applications such as scientific research, telecommunications, medicine and military technology.
