Widefield, high N.A. objective lenses

The objective lens features a high 0.35 N.A. and low distortion equivalent to those in top-end microscopes, while achieving a long 50mm working distance at all magnifications. They can be used with all four models (VM-3020, 6555, 10080, H3030).

Standard head with 15X high-speed zoom

The standard head features 5-step, 15X high-speed zoom, providing greater flexibility in choosing magnifications according to the size of the measuring area.

Color cameras can be used (optional).

TTL Laser AF with long working distances

TTL Laser AF provides high resolution, long working distances, and fast operating speed for perfect focusing on narrow spaces at low magnifications. High-speed scanning measurement is possible at a rate of 1000 points per second max., enabling ultra-precise Z-axis measurements in a variety of applications.

High-speed, high-precision Vision AF

Thanks to the adoption of a new algorithm and a progressive scan type of camera, Vision AF now provides greater speeds and accuracy closer to those with TTL Laser AF. Vision AF is convenient for applications where TTL Laser AF cannot be used, for example, when focusing on chamfered or round edges.

Four illumination choices

Illumination window

The VMR series comes with four illumination choices to provide illumination perfect for the workpiece to be measured. These include:

Two types of 8-segment LED ring illumination
Episcopic illumination (top light)
Diascopic illumination (bottom light)

Edges previously difficult to capture can be detected with high resolution.
In addition, the VMR series features automatic light intensity control to provide the same brightness to multiple NEXIV systems without the need to edit the teaching program.

8-segment LED ring illumination

An illumination system consisting of inner and outer ring illuminators has been specially developed for the VMR series. The system makes possible observations of extremely low-contrast edges which are usually invisible under episcopic illumination by arbitrarily combining illuminations from eight directions. Best for edge enhancement of the contours of bosses, pins, ceramic packages, and similar workpieces.

Inner ring illuminator (37° from the optical axis)
This type can be universally used whenever strong illumination from various directions is needed. This illumination also provides a full 50mm working distance.

Outer ring illuminator (75° from the optical axis)
This type enables the observation of workpieces that are impossible with lighting at a shallow angle. When not in use, the illuminator retracts, creating more space over the workpiece. When in use, the working distance will be 10mm.
