Starrett AVR Automatic Video Measuring Machines


The Starrett AVR Series CNC automatic vision metrology systems are ideal for repetitive measurements and automatic comparison to CAD files. They are available with dedicated 6.5:1 zoom optics or a quick-change bayonet lens mount which accepts a choice of telecentric lenses for micron-level resolution and optical distortion down to 0.001% for accurate field-of-view (FOV) measurements.

The AVR can encompass an entire small part up to 2.00″ x 1.50″ or a feature of a larger part and be seamlessly integrated with stage motion to measure parts with a length up to 8″ (AVR200) or 12 (AVR300). AVR Series hardware features include a granite base for maximum stability, recirculating ball linear guides for smooth and precise stage motion, and full CNC control for high throughput.

The AVR Series consists of two models for 8″ x 4″ x 8″ or 12″ x 8″ x 8″ of X-Y-Z travel. Both provide motorized travel and zoom, which can be under full software control (CNC operation), or under manual control via a joystick and trackball. Available with interchangeable telecentric lenses for field-of-view (FOV) measurements and with optical zoom, these new CNC vision metrology systems are easy to use, versatile and accurate. They are equally suitable for individual measurements, for high-speed “go-nogo testing of small parts within the FOV, and for automatic testing of parts up to 12″ (300 mm) using stage motion.
