In 1992 Schmidt & Bender Hungaria Optik GmbH in Budapest, Hungary was founded as an independent company by Schmidt & Bender GmbH & Co. KG, Biebertal, Germany. The process of privatisation in Hungary made it possible for Schmidt & Bender to buy the production of precision optics and fibre optics from the government-owned enterprise of the Hungarian Opticai Works (MOM).
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 ...
Light path in a Cassegrain reflecting telescope. The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas, the main characteristic being that the optical path folds back onto itself, relative to the optical system's primary mirror entrance aperture.
The Large Binocular Telescope at the Mount Graham International Observatory in Arizona uses two curved mirrors to gather light. An optical telescope is a telescope that gathers and focuses light mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct visual inspection, to make a photograph, or to collect data through electronic image sensors.
In case of damage, the hole must often be drilled and re-threaded, and M4x0.7 or #8–40 may then be relevant alternatives. Remington 700 pattern. The Remington 700 Short Action (SA) scope base attachment pattern is particularly widespread, and is for example used on models such as: [54] Remington Model 722, 40x, 78, 740, 742, 760, 710, 721 ...
The Schmidt–Cassegrain design is very popular with consumer telescope manufacturers because it combines easy-to-manufacture spherical optical surfaces to create an instrument with the long focal length of a refracting telescope with the lower cost per aperture of a reflecting telescope. The compact design makes it very portable for its given ...
SWAROVSKI OPTIK, headquartered in Absam, Tyrol, Austria is part of the Swarovski group of companies. Founded in 1949, the Austrian company specialises in the development and manufacturing of long-range optical instruments in the premium segment of the market, including binoculars, telescopes (spotting scopes), rifle scopes, range finders and night sight devices.
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.
