Optical Measurement
Quality Vision International (QVI)Request Info
The QVI TurnCheck from Quality Vision International Inc. is a precision optical instrument for the measuring of shafts and other cylindrical parts.
QVI TurnCheck systems address the major sources of uncertainty
found in shaft measurement by focusing on advanced optics, thermal stability, and ease of use. The illumination system produces highly collimated light with a constant wavelength, eliminating the wraparound effect on turned parts. The receiving optics are fully telecentric with each element designed to eliminate distortion. The result is a crisp, uniformly magnified image across the entire field of view, with no edge effects or exclusion zones.
TurnCheck systems are designed to deliver accurate measurements in shop floor
conditions where vibration and temperature variation are common, and the materials used help to mitigate the effects of thermal variation found in shop floor environments.
