Using the world’s smallest commercially available steel ball bearing, MinebeaMitsumi Inc. has built the world’s smallest fidgetsSpinner. In measuring just 5.09 mm (0.20 in) long, a system capable of measuring the device accurately is required. This is where the NEXIV VMR-3020 comes in. The high precision system is designed for superior edge detection, even in transparent materials. This is crucial for accurately measuring such small items with tight tolerances.
In the video below, watch the NEXIV VMR-3020 measure the world’s smallest fidget spinner.
Nikon Metrology’s NEXIV VMR-3020 is designed for accurately measuring small items with tight tolerances. Find out more about Nikon’s NEXIV range here.
