Benefits & features
Built-in digital counter and protractor
The V-20B comes standard with a built-in digital counter and protractor, making this one of Nikon's most advanced comparators.
5 Types of projection lenses
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.
Workpieces up to 20kg measurable
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.
Parfocal projection lenses
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 magnification 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.
Designed to measure heavy workpieces
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.
