Cylindricity standard

The Hall effect chopper has stable chopping frequency and high accuracy, making it an essential component for modern modulation optical measurement. It is mainly used in optical fibers, pulse generators to emit pulsed light from lasers, or fast choppers to convert continuous light into pulsed light

Calibration block

A calibration block is a cylinder with a small plane around its circumference. The chord height value of the small plane on the radial section of the cylinder is the calibration value of the calibration block. Calibration blocks are used to verify instrument characteristic parameters.
