The VB400 vertical projection comparator allows flat parts to be simply laid on a glass insert in the workstage. Features include
a 16″ diameter vertical screen, ultra-bright LEDs for long-life illumination, linear encoder scales for 0.00002″ (0.5μm) resolution,
and angle readout to 1 minute resolution. Available with stages with 8″x4″ or 10″x 6″ of travel. Options include six projection
lenses from 10X to 100X and a choice of digital interfaces.

Field Of View Terminology
Working Distance: Is the distance between the objective lens and the component when the component is in focus
Field Of View (FOV): Is the viewable area. To fill the 16″ (400 mm) diameter screen when using a 10x lens, the maximum diameter object projected would be 1.6″ (40 mm).
Half Field View: Is the maximum size a component can be projected to the center of the screen before colliding with the lens.
Full Field of View: Is the maximum size a component can be projected over the full screen before colliding with the lens.
Projected Image: Is how a component is projected onto the screen in relation to its placement on the workstage.
