Vision Systems

  • Video-Based Measurement Systems  combine high-resolution graphic images, powerful-intuitive software and precision mechanical platforms, to deliver superb accuracy and repeatable measurement results. A new large field-of-vision (FOV) Benchtop Vision Measurement System, the HVR100-FLIP, is capable of being used in either a vertical or horizontal orientation. 


  • Digital Optical Comparators  are vision metrology systems that function like horizontal optical comparators, and offer an added benefit of having a DXF "digital overlay".

Examining Non-Contact Inspection for Small Part, High Volume Production
This article looks at current video measurement options for precision measurement.

Optical Comparators Provide Quickness And Accuracy
Imagine having to take measurements of a part that is 2 inches in diameter or smaller by hand. It would be almost impossible to produce an accurate measurement of a complex part. This is why optical comparators, also known as measuring projectors, are useful for shops that measure/inspect small parts, such as those in the medical or aerospace industries.
