Telescopic measurers - Import export

Knight Optical can offer transmit and receive windows and mirrors for LIDAR systems using visible, NIR (0.9 to 1.5µm) and Mid-Waveband Infra-Red (MWIR, 3 to 5µm) light. Since the 1960s, scientists have used LIDAR (light detection and ranging) to study the atmosphere. Short pulses of laser light are used to detect particles or gases in the atmosphere, like a radar bounces radio waves off rain drops in clouds. A telescope collects and measures reflected laser radiation, like a radar dish collects the radar signal, leading to a profile of the atmosphere's structure along the path of the laser beam. Researchers can then determine the location, distribution, and nature of atmospheric particles and molecular species using an advanced LIDAR method called the Differential Absorption Lidar (DIAL) technique.

HEIDENHAIN angle encoders with integral bearing are characterized in particular by very high system accuracy. The integral bearing in the encoders eliminates any effect on measuring accuracy from the bearing of the machine components. The integrated stator coupling in the RCN/RON/ECN series encoders guarantees lowest possible error from the effect of tolerances in the shaft coupling. All angle encoders with integral bearings feature shaft seals that ensure resistance to contamination (IP64 protection). These encoders enjoy an entire spectrum of possible applications in machine tools, measuring machines, telescopes, printing machines and many other areas. Absolute measuring method Hollow shaft diameter (up to 50 mm) Integrated stator coupling Simple installation Typical field of application: Rotational axes with reduced accuracy requirements

A major hallmark of HEIDENHAIN angle encoders is their very high system accuracy. This makes them particularly advantageous in demanding applications for machine tools, measuring machines, telescopes, printing machines, etc. Because the bearing is integrated into the encoder, machine component bearings have no effect on the measuring accuracy.

The signals representing angle and length of a telescopic crane are important measuring data. Determination of such measuring data is performed by means of tilt angle and rope length transmitters. The determination of the jib angle is performed by a magnetically damped pendulum system, the swing of which is measured with a redundant high-resolution conductive plastic potentiometer. The output signal is provided in form either of two resistance signals or via the built-in signal converter in form of two current or voltage signals. Linear measurement is performed according to the draw wire measuring principle. One makes use of a multiwire measuring cable, which is wound multilayered on a cable reel provided with a pullback spring. A mechanical spindle lead screw nut ensures, that the rope is rewound and unwound exactly layer-by-layer. The number of drum revolutions, being proportional to the measured length is determined by a redundant potentiometer system voltage or current output.
