Nikon NEXIV VMH-300 Video Measuring Instrument Provides High Speed, High Accuracy, 3D Metrology

avr. 24, 2001

Nikon now offers a high-accuracy edition in their NEXIV video measuring system, the NEXIV VMH-300. The VMH-300 is designed to offer easier operation, faster throughput rates, advanced functions such as comprehensive 3D surface analysis, and updated software to improve workflow. The VMH-300 is also considered to be the fastest, smartest and most accurate video measuring product available in its class.

Featuring glass scales with resolutions of 0.01 micron, the VMH-300 helps the user to obtain super high measurement repeatability and calibrated accuracy with speed and ease-of-use. As Nikon's highest accuracy video measuring instrument, the standard specification for the travelling X-Y accuracy of the system is equal to or less than 1.9 microns over 300mm distance.

Its 300 x 300 x 155 mm travel range is designed to measure demanding parts such as magnetic reader heads, optical fiber parts, stamped or etched parts, high precision molds, and anything requiring exceptionally high accuracy. In addition, the VMH-300 provides through-the-lens laser (TTL) autofocus allowing for high speed, accurate, non-contact Z axis (3D) measurements.

Other features include a V-flat stage guide and Yawing Abbe error-free design resulting in error free readings, ultra straight and flat stage travel, and highly accurate encoder feedback. It also provides dual low thermal expansion, and high resolution (0.01 micron) glass scales.

All NEXIV products offer intelligent search functions to help keep fixturing costs low, a multi-pattern search function that automatically corrects for part-to-part variation along with deviations in expected edge or feature locations, and incorporate the world's brightest and highest contrast optical components for distortion-free viewing.
