Objective: The first lens or curved mirror that collects and focuses the incoming light. Primary lens: The objective of a refracting telescope. Primary mirror: The objective of a reflecting telescope. Corrector plate: A full aperture negative lens placed before a primary mirror designed to correct the optical aberrations of the mirror.
An Ellipsoidal Reflector from a Leko Source Four ERS. Ellipsoidal reflector spot (abbreviated to ERS, or colloquially ellipsoidal or ellipse) is the name for a type of stage lighting instrument, named for the ellipsoidal reflector used to collect and direct the light through a barrel that contains a lens or lens train. The optics of an ERS ...
Left to right: MR16 with GU10 base, MR16 with GU5.3 base, MR11 with GU4 or GZ4 base Line drawing of an LED MR16 lamp, with a heatsink rather than a reflector. A multifaceted reflector (often abbreviated MR) light bulb is a reflector housing format for halogen as well as some LED and fluorescent lamps.
A Lieberkühn mirror from Emil Busch AG (now Rathenower Optische Werke) circa 1930, digital collection of the Deutsches Museum. [1]A Lieberkühn reflector [2] (also known as Lieberkühn mirror [3] or simply Lieberkühn [2] [4]) is an illumination device for incident light illumination (epi-illumination) in light microscopes.
English: Diagram of Ritchey-Chrétien reflector M1 = primary mirror (hyperboloid); M2 = secondary mirror (convex hyperboloid); F = focus Nederlands: Diagram Ritchey-Chrétientelescoop M1 = hoofdspiegel (hyperboloïde); M2 = secundaire spiegel (bolle hyperboloïde); F = brandpunt
Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser.
Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...
Metal substrates ("Metal Mirror Reflectors") may also be used in solar reflectors. NASA Glenn Research Center, for example, used a mirror comprising a reflective aluminum surface on a metallic honeycomb [1] as a prototype reflector unit for a proposed power system for the International Space Station. One technology uses aluminum composite ...
