Nexiv High Accuracy Edition Series VMH-300
VMH300 Picture The new NEXIV VMR series is set to become the standard by which all other vision metrology systems are measured. Its brand new telecentric optic system has been designed to make it the best in the world. An Objective lens with a working distance of 50mm and the same superb numerical apertures found in top-end microscopes are both standard features. The world's widest 15X - zoom ratio provides ample field of view during low magnification observations and excellent resolution at high magnifications.

A rigid stage offers controlled speeds of 300mm/sec - .5 times faster than previous Nexiv models - and offers significantly higher U2 accuracy with a guaranteed U2XY of 2.5+2.5L/1000?m (VM 6555). Image processing speed has also increased dramatically and the combined result of all the changes and improvements is a machine that offers a considerably higher work throughput.
