Optical parallels are standard parallel gauges for high-precision metrology, precision-manufactured from highly homogeneous optical glass or quartz. They verify flatness of measuring faces on micrometers, lever micrometers, and snap gauges, and parallelism between opposing measuring faces, serving calibration, laboratories, and precision inspection. The series has4 measurement-range sections, each containing6 dimensional groups for instruments of different ranges. Closely controlled parallelism and flatness ensure accurate, reliable verification.

Applications

Metrology verification organizations: flatness and parallelism verification of micrometers, lever micrometers and snap gauges. Industrial laboratories: periodic calibration and inspection of precision gauges for accurate measurements. Production quality control: routine verification and maintenance of gauges in machining workshops and quality departments. Research and teaching: standard parallel gauges for metrology instruction and precision experiments.

Key Features

Precise parallelism/flatness: both working faces are precision polished to minimal parallelism error for accurate inspection of gauge measurement faces. Excellent homogeneity: few impurities, no bubbles/striae and good thermal stability preserve long-term accuracy. Range groups 0-25, 25-50, 50-75 and 75-100mm contain multiple sizes for micrometer/snap-gauge calibration. Smooth, wear-resistant surfaces withstand repeated contact tests for long life. Broad use: periodic metrology of mechanical/lever micrometers, calipers and other gauges. Yasi Optical advantages: quality optical glass/quartz with stable homogeneity preserves parallelism/flatness; precision-polished dual faces ensure reliable results; mainstream groups/sizes stocked for rapid range coverage; custom sizes/grades suit nonstandard metrology; every flat fully inspected for parallelism, flatness and surface finish.
