Veeco Instruments Inc.Request Info
 
Veeco Instruments Inc. has unveiled the ContourGT Surface Metrology product family, its 10th generation of noncontact, 3-D optical surface profilers. Based on proprietary white-light interferometry technology, the devices feature patented higher brightness and dual-LED illumination. They produce fast angstrom-to-millimeter vertical resolution over large fields of view, with flexible sample setup and good repeatability to enable precision measurements, even in difficult applications. Featuring 64-bit multi-core computer operation with the company’s Vision64 operating and analysis software, and an intuitive, modular user interface, the profilers are designed to increase yield and decrease manufacturing costs. They are suitable for use in production quality assurance/control and R&D machining and manufacturing applications within the high-brightness LED, solar, ophthalmic, semiconductor, medical device and academic research markets.

GLOSSARY
interferometry
The study and utilization of interference phenomena, based on the wave properties of light.
metrology
The science of measurement, particularly of lengths and angles.
ophthalmic
Pertaining to the human eye.
optical profiler
Also known as a white-light interferometer. Measures surface texture and shape from nanometer-scale roughness to millimeter-scale step heights. A standard arrangement includes an illumination source, traditionally a tungsten-halogen bulb, coupled to an optical system with a variety of interferometric objectives.
vertical resolution
In television system specifications, the number of parallel horizontal black and white lines of equal thickness, that can be resolved from top to bottom of the raster. (One line equals either a black or white line.)
