Nikon's benchtop optical comparator with enhanced features for improved precision and ease of operation.
Nobody knows better than Nikon how to combine greater precision with easier operation; so you can concentrate on your project and not on your equipment. These projectors feature a 12" diameter screen and accept larger stages with higher accuracy thanks to the movable head during focusing. They are also completely user-friendly, complete with a built-in digital XY counter and digital protractor counter. What's more, the V-12B lets you easily view erect images, making theprofile projector easier than ever to operate.
Large Stage Mountable
The V-12B adopts a focusing mechanism that achieves focus by moving the objective head up and down, allowing stages with longer cross travel to be mounted. When the 10x6 stage is used, the projector can measure areas as wide as 250 x 150mm.
Adjustable Base Feet
Because the rigidity of the instrument has been increased, workpieces as tall as 100mm can be loaded.
Projection Lenses
Three projection lenses can be mounted to the rotary turret at one time. All projection lenses, 5x to 500x, boast high resolution and minimal distortion, while their working distances are longer than competitive lenses.
Four-step Zooming Condenser Lens
When contour illumination is used, this condenser lens delivers the right amount of light to suit the magnification of the projection lens selected. The DIA condensor must be used with this lens when the magnification is 200x or 500x.
Switchable Vertical/Oblique Illumination
The built-in surface illuminator can be switched between vertical and oblique illumination, making detection of edges in resin parts and other workpieces much easier.
Erect Images
Projection images are erect and unreversed for easy measurements, and their quality is as sharp as inverted images.
Built-in Digital Counter and Protractor
The V-12 Series features 4 models. The V-12BDC and 12BSC types come with a digital XY counter, while the V-12BDC and V-12BD types have a built-in digital protractor for greater ease-of-use.

| Oblique Illumination : | Oblique surface illumination can be obtained by tilting EPI illumination unit |
| Contour Illumination: | Telecentric type. 200x and 500x lenses should be used with a DIA Condenser Lens. |
A larger capacity vertical projector features a 20" screen and permits mounting of a large stage.
With improved image brightness and resolution, the V-20B delivers images with excellent clarity, while enabling observation in a comfortable posture. It features a large effective screen diameter of 500mm and includes a built-in digital counter and digital protractor.
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 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.
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.
