Horizont al Digit al Video Compara tors HDV HDV300 AND HDV400 HDV300 CNC, HDV400 CNC AND HDV500 CNC 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,they are configured like a traditional horizontal comparator.The workstage is the same as the Starrett field-proven comparators. The heart of the HDV system centers on a uniquely designed interchangeable lens mounting system coupled to a hi-resolution 5 mega-pixel digital video camera.The system is available with a choice of seven telecentric lenses for micron-level resolution and optical distortion as low as 0.001% for accurate field-of-view (FOV) measurements. With MetLogix™ 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. Systems are available in manual or CNC control.
