| Renishaw specialized in automated metrology, manufactures products for automation of CMM and CNC machine tool operations, calibration, encoder, scanning and spectroscopy systems. The Renishaw Group's products: CMM probe systems, Machine tool probe systems, Calibration products, Encoder products, Laser scale systems, Scanning products and Spectroscopy products. Renishaw has developed a low cost, ultra-fast 2-D imaging Raman microscope for spectral analysis of materials. Two versions are available, a standard laboratory model using a conventional microscope for viewing and an industrial model for more general use where a monitor screen displays the Raman images and spectra. System 100 compact Raman spectrometer uses dedicated fibre optic probes which enable sampling at up to 100m distance. Raman spectra can be acquired from sample sizes 1ґm to more than 150mm. Renishaw has established a Raman gemological and mineralogical materials database, the first library of Raman spectra to be commercially available. It contains nearly 1,000 entries of over 500 different minerals and gems and can be used for the identification of unknown samples. The Raman microscope which uses ultra-violet (u.v) light rather than the more usual visible light excitation of other instruments in the range. The resultant Raman "scattering" occurs at a shorter wavelength than most fluorescence and is not masked by it. The spectrograph uses specially developed laser-blocking filters and a single diffraction grating to give unprecedented throughput and signal-to-noise values. In addition to biochemistry applications, materials science eg direct measurement of the hydrogen content of hard carbon films, and forensic science eg detection of explosives on fabrics, have already benefited from the system's increased sensitivity. New accessories include an UV enhanced CCD camera. Also Compact diode laser designed as a source for optical spectroscopy. A DLC (diamond-like-coating) analyser, using Raman spectroscopy, for quality control purposes in the production of hard disk drives. Using Renishaw's unique PASS software, the analyser can be semi-automated to give a simple pass / fail message, in addition to full operating parameters for process development. |
