Starrett optical comparators provide a time-tested, cost-effective solution for non-contact measurement. In this easy-to-learn technology, the image of a part is projected on a screen at a precisely known magnification. Measurements can then be taken off the image by moving the system’s X-Y stage, or the image can simply be compared to a transparent overlay.

“Rugged, Accurate & easy to use.”

Horizontal Bench Top Optical Projector

The most economical of our bench top comparators, the HE400 offers a 16″ (400mm) diameter screen, X-Y stage travel, bayonet-style interchangeable lens mount, and Q-axis angular readout: all to improve capability and performance. These horizontal bench top comparators are fitted with MetLogix™ tablet M1 or M2 PC-based touch screen measuring software as standard, making them simple to use, but having the power to satisfy the most complex measuring requirements.

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″ (400mm) diameter screen when using a 10x lens, the maximum diameter                                           object projected would be 1.6″ (40mm).
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.
