Digital optical comparator HDV 400

horizontalbench-top

The HDV Horizontal Digital Video Comparators combine the best features of a horizontal optical comparator and a vision metrology system. The HDV is 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 patented 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. • Steel and aluminum construction with hard anodized stage tooling plate and riser • 21.3" x 5.1" (540mm x 130mm) workstage • 110lbs (50kg) maximum load capacity • 2" (51mm) of focus travel • Manual X-Y and focus positioning via hand wheels or CNC with joystick and trackball positioning • Heidenhain glass scales for 20µin (0.5µm) X and Y resolution • LED illumination for surface and profile lighting • 5 mega-pixel color video camera (2448 x 2058 pixels) • Software and part image displayed on 24" (60cm) touch-screen color monitor (1920 x 1080 pixels) • 6 interchangeable telecentric lenses for fields of view from 1.14" to 0.09" (29mm to 2.3mm) (patent US 9,360,435 B2) • Interchangeable 6.5:1 zoom optics
