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 ...
The PASCAL Photocoagulator is an integrated semi-automatic pattern scan laser photocoagulation system designed to treat ocular diseases using a single shot or predetermined pattern array. The device is for ophthalmologists , particularly those that focus in vitreo-retinal surgery, a type of eye surgery .
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.
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 ...
Red free photography is also regularly used as a base line photo prior to Angiography. [13] Angiography is a process of photographing/recording vascular flow within the retina and surrounding tissue by injecting a fluorescent dye into the blood stream. This dye fluoresces a different colour when light from a specific wavelength (excitation ...
A resistor–inductor circuit (RL circuit), or RL filter or RL network, is an electric circuit composed of resistors and inductors driven by a voltage or current source. [1] A first-order RL circuit is composed of one resistor and one inductor, either in series driven by a voltage source or in parallel driven by a current source.
Alcotán-100 is a recoilless, one-man portable, single-use (firing control unit is reusable) anti-tank rocket launcher system used by infantry, manufactured by Instalaza. [1] [3] The firing control unit predicts the future aiming point based on calculation before the rocket fire. [1]
The Advanced Target Pointer Illuminator Aiming Laser, ATPIAL AN/PEQ-15 known colloquially as the "PEQ-15" [/ p ɛ k / / f ɪ f t iː n /] produced by L3Harris (originally designed and manufactured by Insight Technology, until their acquisition by L3Harris in 2010); is a multifunction IR Target Pointer & Illuminator, a.k.a. a Laser Aiming Module (LAM) for use as a rifle attachment, using a ...
