Optical engineers use the science of optics to solve problems and to design and build devices that make light do something useful. [3] They design and operate optical equipment that uses the properties of light using physics and chemistry , [ 4 ] such as lenses , microscopes , telescopes , lasers , sensors , fiber-optic communication systems ...
The word 'Photonics' is derived from the Greek word "phos" meaning light (which has genitive case "photos" and in compound words the root "photo-" is used); it appeared in the late 1960s to describe a research field whose goal was to use light to perform functions that traditionally fell within the typical domain of electronics, such as telecommunications, information processing, etc ...
Houghton doublet corrector design equations – special case symmetric design. The Houghton telescope or Lurie–Houghton telescope is a design that uses a wide compound positive-negative lens over the entire front aperture to correct spherical aberration of the main mirror. If desired, the two corrector elements can be made with the same type ...
Optical lens design is the process of designing a lens to meet a set of performance requirements and constraints, including cost and manufacturing limitations. Parameters include surface profile types (spherical, aspheric, holographic, diffractive, etc.), as well as radius of curvature, distance to the next surface, material type and optionally tilt and decenter.
The few scopes sold to a limited number of law enforcement agencies and even fewer civilians were marked "10x Sniper" and carried a "T" prefix on the serial numbers. Servicing of these scope were taken over by U.S. Optics who also produced their own version and used the nomenclatures MST-100 for the 7.62 scope and MST-150 for the .50 BMG Scopes.
In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. [1] Aberrations cause the image formed by a lens to be blurred or distorted, with the nature of the distortion depending on the type of aberration.
Meade's literature describes their ACF as a variation on the Ritchey-Chrétien telescope, although it does not use the two hyperbolic mirror combination in that design (being more of an aplantic design). [16] Models. LX90-ACF, 8" to 12" [17] LX200-ACF, a series of LX200 with ACF Optics 8" to 16" [18] LX400-ACF, 16 to 20" f/8, w/ robotic ...
In optics, a relay lens is a lens or a group of lenses that receives the image from the objective lens and relays it to the eyepiece. Relay lenses are found in refracting telescopes, endoscopes, and periscopes to optically manipulate the light path, extend the length of the whole optical system, and usually serve the purpose of inverting the image.
