300 Series

The 300-Series VisionGauge® Digital Optical Comparator Field-of-View Systems are extremely cost-effective systems that are ideal for smaller parts (up to 5.5″ x 3.3″). The 300-Series has no need for overlays, templates, or Mylars™ and can check multiple parts regardless of their orientation.

The VisionGauge 300-Series have an extended depth-of-field for tall parts (as high as 4.0″) and a long working distance that provides ample clearance and room to work between the part and the lens.

They produce a stunning super-high-resolution image to carry out fine, detailed inspections.

Three different types of LED illumination are standard: collimated back, front off-axis (i.e. “dark field”) and front on-axis (i.e. “bright field”). This allows the system to produce crisp, sharp edges and perform beautifully even when working with hard-to-image materials (for example: shiny, reflective or even translucent surfaces) and difficult geometries (such as deep holes).

VisionGauge® Digital Optical Comparators are complete, ready-to-run Windows-based solutions. They are delivered network-ready and include on-site installation, NIST-traceable calibration & training.

The 300 Series Field-of-View Systems are desktop instruments that have all of the functionality of the 500 Series VisionGauge® Digital Optical Comparators, with the sole exception that they are limited to smaller parts.
