Topcon Corporation acquired Advanced Grade Technology in 1995 and became known as Topcon Laser Systems. In August 2000, Topcon acquired JPS Inc., of San Jose, California, a provider of precision GPS and GPS/GLONASS products. With the introduction of a series of positioning products, Topcon Laser Systems grew, and consolidated the survey ...
An interactive electronic technical manual (IETM) is a portal to manage technical documentation. IETMs compress volumes of text into just CD-ROMs or online pages which may include sound and video , and allow readers to locate needed information far more rapidly than in paper manuals.
However, it was not until 1963 the Topcon name became famous by introducing the Topcon RE Super, an event that took the entire camera industry by surprise: This camera featured through-the-lens exposure metering, at full lens aperture. The RE Super was fully prepared for professional work, supported by a choice of lenses and accessories to ...
In the early 1990s, Sokkisha started a corporate identity project to improve and expand the company's global marketing. The result of this project was a new brand name: Sokkia. In 2008, Sokkia became a fully wholly owned subsidiary of Topcon. [3]
A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.
A laser warning symbol. Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.
The laser damage threshold (LDT) or laser induced damage threshold (LIDT) is the limit at which an optic or material will be damaged by a laser given the fluence (energy per area), intensity (power per area), and wavelength. LDT values are relevant to both transmissive and reflective optical elements and in applications where the laser induced ...
Helium–neon laser at the University of Chemnitz, Germany. A helium–neon laser or He–Ne laser is a type of gas laser whose high energetic gain medium consists of a mixture of helium and neon (ratio between 5:1 and 20:1) at a total pressure of approximately 1 Torr (133 Pa) inside a small electrical discharge.
