HDV Series

HDV Horizontal Digital Video Comparators

The HDV Horizontal Digital Video Comparators combine the best features of a horizontal optical comparator and a vision metrology system. With a rigid steel design, the HDV is configured like a traditional horizontal comparator. The workstages are the same as the Starrett field-proven HB400 bench top and HF750 floor standing comparators, with a 110lb (50kg) and 330 lb (150kg) load capacities respectively. The heart of these systems centers on a uniquely designed interchangeable lens mounting system coupled to a hi-resolution color digital video camera (patent pending). These systems offer zoom optics or a choice of telecentric lenses for micron-level resolution and optical distortion as low as 0.001% for accurate field-of-view (FOV) measurements. Telecentric lenses provide a maximum field of view of up to 3 x 2.5″ (76.5 x 64mm). Stage movement can be related to the imported file allowing part comparison up to 12″ (300mm) on the HDV300, 16″ (400mm) on the HDV400, and up to 20″ (500mm) on the HDV500.

The HDV systems house a powerful 64-bit PC, which runs MetLogix™ M3 Metrology software. With M3 software, DXF CAD files can be imported and 2D “Go-No-Go” digital overlays can be developed directly from the CAD files. Video edge detection (VED) allows real-time interaction of the imported file with the video image of the part being inspected. Productivity, speed and accuracy are all enhanced. HDV300 and HDV400 systems are available in manual or CNC control, while the HDV500 CNC control is standard.

Horizontal Digital Video Comparator

The HDV300 and HDV400 X-Y stage travel are 12 x 6″ (300 x 150mm) and 16 x 6″ (400 x 150mm) respectively. Each HDV Digital Video Comparator features a 5-megapixel color video camera and a choice of zoom optics or seven telecentric lens options (US Patent No. 9,360,435) for ultra-low optical distortion field-of-view (FOV) measurements.
