Nikon V-20B Optical Comparator

The V-20B comes standard with a built-in digital counter and protractor, making this one of Nikon’s most advanced comparators.

Five types of projection lenses are available for the V-20B, 5x field of view 100mm, 10x field of view 50mm, 20x field of view 25mm, 50x field of view 10mm, 100x field of view 5mm.

The stage up/down movement unit is rigidly built, and if the 10 x 6 stage is used, workpieces as heavy as 20kg can be loaded. The measurable range has been increased to 250 x 150 mm.

All projection lenses have the same parfocal distance and feature long working distances. The built-in half mirror eliminates the need to adjust illumination each time the magnifcation is changed. With improved image brightness and resolution, the V-20B delivers images with excellent quality, while enabling observation in a comfortable posture by rectifying the eye-point height.

The stage up/down focusing and the 10x6 stage are designed to handle the load of workpieces as heavy as 20kg while maintaining measuring accuracy tolerances.
