GRAPHICS RESONANT SCANNER (GRS and GRS-PS)
Scanner for high resolution applications
The
GRS series, and the GRS-PS series that has an integral position sensor
(PS), have been designed and developed for high resolution applications
in graphic-art quality imaging, photo-typesetting, surface inspection
and similar applications requiring extremely high accuracy. Their
highly repeatable sinusoidal scan ensures the accurate placement of
pixels (dots) in the cross-scan direction.
Drive electronics
Optional drive electronics are available to provide an easy way for you to incorporate the scanner into your system.
Features
•Scan-frequencies………..Up to 250 Hz
•Optical scan angle ……. Up to 60° peak-to-peak
• Rotational axis wobble …….. 0.5 arcsec (2.4 µrad)
•Rotational axis ………..Close to the mirror surface
•Rugged construction …………………No wearing parts
•Service life ………………virtually unlimited
Repeatability
The
GRS and GRS-PS provide a consistently repeatable Performance, because
there are no bearings or other wearing Parts , as in rotary and linear
scanners.
Low cross-axis wobble is achieved by a patented flexure Design that embodies two sets of twin crossed S-FlexTM
Integral position sensor (PS)
The
GRS-PS has an integral position sensor. The position sensor is based on
an elecrooptic subsystem that gives an analog single that is
consistently repeatable. It is insensitive to ambient temperature
variations, and has high signal to noise ration.
In conjunction with
an A-to-D converter, timings signals can be provided for placing
equally spaced dots .These timing signals compensate for the
sinusoidal scan characteristic of the resonant scanner.
Quality
Our
state of the art measurement technique guarantees to you that every GRS
scanner performs to specification. Each scanner is tested, and
“burnt-in” for 100 million cycles prior to shipment, to ensure customer
satisfaction.
Remarkably Economic
Feature-for-feature, the GRS offers the highest performance for the lowest cost of any comparable scanner in the market today.
Please call for technical and sales assistance. We can custom design to your requirements.
