Nexiv VMR 6555
VMR6555 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/1000µm(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.

Illumination
    Ring Light Image Subject illumination is now available in a variety of formats depending on the type of work and nature of the measurement task. Options include Episcopic (top light) illumination, Diascopic (bottom light) illumination, and a new twin 8-segment LED ring illuminator with variable height outer ring.
    Nikon's unique LED ring illumination design allows observations of very low contrast edges, usually impossible under conventional episcopic illumination. Lighting can be perfectly controlled by combining illumination from any of the eight different segments and positioning of the outer ring to enhance features and edges. In practice this has proven to be useful for edge enhancement of the contours of bosses, pins, ceramic packages and similar low contrast work pieces.

TTL laser auto focus technology
The standard TTL Laser auto focus technology now provides higher accuracy and a longer working distance of 50mm. TTL Diagram High-speed auto focus is now possible regardless of surface conditions within the work piece. The TTL laser technology also enables ultra precise Z-axis scanning be taken (up to 1000 points per second). Measured work pieces can be shown in a birds-eye view or as a 2-dimensional cross section.

Self-teach technology
NEXIV VMR is far easier to use than ever before. Each operation contains a self teach wizard, providing a step-by-step guide to even the most complex operations. In addition the interactive measurement wizards can guide an operator through exactly what is required to perform a specific measurement task. For frequent operations using the same procedure operators can create customized wizards.
NEXIV can also import CAD data. The online CAD interface program is provided as standard and allows the import of a variety of CAD file types including IGES, DXF, Gerber and Excellon. The operator can display the graphics on NEXIV VMR AutoMeasure facilitating teaching and shortening working time. Measured data can also be converted to DXF files making for easier reverse engineering processes.
