Calibration of Gauge Blocks by Interferometry
• Gauge blocks are essential for dimensional metrology traceability.
• Optical interferometer is the most accurate method for calibrating gauge block length.
• Eurocaltech offers gauge block interferometer (Hexagon / NPL) measurements.
• Two frequency stabilized He-Ne lasers illuminate the measurement chamber.
• Measurements conform to BS EN ISO 3650:1999 and BS 4311-1:2007.
• Measurement uncertainty in units of 1µm.
