Maximum load capacity of 22lb (10kg).
Manual motion control with fine adjustment for X and Y axes.
Bayonet lens socket for quick magnification changes.
Dual mirror design for vertically correct images.
Heidenhain glass scales for 0.00002" (0.5µm) resolution.
LED profile and surface illumination.

Options:

Projection lenses ranging from 10X to 100X.
Larger workstage option with 10”x6” (250x150 mm) travel.
Fiber-optic edge detection and various digital readout options.
Cabinet stands of 23" (58cm) or 32" (81cm).

Software and Digital Interfaces:

MetLogix M2 software on a tablet PC with touch-screen operation, supporting 2D geometry and CAD file import/export.

Starrett Optical Comparators Rugged, Accura te & easy to use Starrett optical comparators provide a time-tested, cost-effective solution for non-contact measurement. In this easyto-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. Our optical comparators combine mechanical stability with precision optics and versatile lighting to produce bright, sharp images and exceptional accuracy. We offer models in different...
