TurnCheck System Addresses Shaft Measurement Uncertainty

Originally titled 'System Addresses Shaft Measurement Uncertainty'

QVI’s TurnCheck is a precision optical instrument for measuring shafts and other cylindrical parts that addresses the major sources of measurement uncertainty found in shaft measurement.

QVI’s TurnCheck is a precision optical instrument for measuring shafts and other cylindrical parts. The system address the major sources of measurement uncertainty found in shaft measurement today, by focusing on advanced optics, thermal stability and ease of use.

The system’s optics have been designed and manufactured by QVI. The illumination system found in TurnCheck systems produces highly collimated light with a constant wavelength, eliminating the wrap-around effect on turned parts. The receiving optics are fully telecentric with each element designed to eliminate distortion. 

The systems are designed to deliver accurate measurements in shopfloor conditions where vibration and temperature variation are common. The design of the system mitigates the effects of thermal variation found in shopfloor environments.
