Nexiv VMR 3020 Nii
     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.

Key Features Include:
Technical Specifications:
  • The VMR-3020Nii is an entry-level product with the TTL Laser and one of the two LED rings removed. All the great features of the VMR-3020 at an attractive price point.
  • New Telecentric 15:1 zoom optical system with 0.3 numerical aperture and 25 millimeter working distance. 
  • New dual ring programmable oblique LED illuminators, each ring has 8 independent segments. 
  • Improved stage accuracy with new design lower coefficient of expansion scales with 0.1-micron resolution. 
  • More stringent stage accuracy specifications, all stages are U2 compliant. 
  • High accuracy, high speed through the lens Laser with 8-micron spot size. Scans a 1000 points a second and has a 25-millimeter working distance
  • Faster image acquisition and improved system speed with a progressive scan black and white camera. 
  • New separate system controller with all electronics along with halogen episcopic and diascopic illumination built in. This removes heat source and vibration from fan illuminators from main stand.
  • High-speed local area network connection (LAN) between the system controller and the computer improves program run time along with improved laser and video auto focus performance. 
  • New 300 by 200 millimeter steel stage on VMR-3020 with ball screw design cross roller bearing guides. (Fast, Accurate, Durable)
