Leitz Infinity Coordinate Measuring Machine: Refined Touch

The coordinate measuring machine Leitz Infinity from Hexagon Metrology enters the new year with sophisticated sensors and a forthcoming new model. A new version of the proven Leitz LSP-S4 measurement head heralds the start of the new year: the LSP-S4 Ultra Low Force is available immediately on the Leitz Infinity. Thanks to the low trigger force of this measurement head of up to 0.005 N, no scratch marks or any other damage is caused to the part during inspection. more11.06.2010

GigE Vision for 3D Medical Research

Rheumatoid Arthritis is a widespread autoimmune disease that attacks many tissues and organs, but principally affects synovial joints (hands, feet, knees and elbows) causing chronic inflammation as well as deformation. Rheumatoid arthritis affects millions of people of all ages worldwide. Although there is no known cure for the disease to date, medications to relieve symptoms and prevent joint destruction and deformity are widely available. more27.05.2010

Unique Requirements Attractively Met

At one time micro video lenses for compact machine vision systems supported only low resolution applications. Reductions in the size and cost of optical sensors along with increases in pixel count now allow high resolution in compact systems. New optical designs are yielding micro video lenses with increased resolution to match today's sensors, increasing their applications range. more20.05.2010

Optical Metrology Basics: Radiometry

Radiometry provides methods and quantities for the characterization of the intensity of radiation with emphasis on applications in optical metrology. Whenever the signal in an optical sensor in combination with the associated lighting system must be estimated, the quantities and concepts of radiometry come into play. Should you like to know whether 10 LEDs will produce a sufficiently high lighting level in the field of view to saturate your camera signal, it my be a good idea to brush-up your knowledge about radiometry. more28.04.2009

High-precision and Non-contact

Novel products are designed nowadays with increasing high standards in production and resource efficiency. In many industrial fields such as automotive, aerospace and medical engineering, some new product features are created which can only be manufactured by means of micro and nano production technologies. more07.04.2009

Optical Metrology Basics: Spectral Sensors

A spectral sensor is a miniaturized spectrometer equipped with a detector array. The spectrometer spreads the incoming bunch of rays according to wavelengths, and the detector array captures the complete spectrum simultaneously during the exposure time. Spectral sensors thus provide detailed access to the spectral information of the incoming radiation. This article describes some of the optical principles of spectral sensors. more
