Starrett’s new 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 HB400 and HD400 comparators, with a 110lb (50kg) load capacity. The heart of the system centers on a uniquely mounted 5-megapixel digital video camera and are 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. Lenses provide a maximun field of view of up to 62mm x 47mm. Stage movement can be related to the imported file allowing part comparison up to 400mm" long.
The HDV systems house a powerful 64-bit PC, which runs MetLogix M3 Metrology software. With this software, DXF CAD files can be imported and 2D Go-No-Go gauges 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.
The HDV Series consists of two models with stage sizes 300mmx150mm or 400mmx150mm of X-Y stage travel. They feature a 5-megapixel video camera and a choice of seven interchangeable telecentric lenses (patent pending) for ultra-low optical distortion field-of-view (FOV) measurements.
Using MetLogix M3 software, DXF CAD files can be imported for direct comparison to the part video image. The HDV series can also perform as a manual horizontal vision system for part measurement utilizing a 6.5:1 zoom lens delivering higher magnifications for increased accuracy.

| The HDV Series is available with a choice of seven telecentric lenses and a 6.5:1 zoom lens. Lenses are installed by a bayonet fitting, which allows quick changeover between magnifications and between FOV or zoom operation by the user. The 0.14X lens has a dedicated mounting configuration and illuminators. |
