本儀器是一種采用量塊或標準件與試件相比較的方式測量物體外形尺寸的儀器。主要用于五等量塊，柱型規及各種圓柱形，球形，線形等物體的直徑或板形物體的厚度的精密測量，對被測件作微小位移測量。亦可用來控制精密件的加工。
The optimeter is widely used to precisely measure external size of workpiece by comparison with a gauge block or standard part. It is applicable for examining 5-grade gauge blocks, cylinder gauges and external sizes of precision parts such as parallel planes, spheres
and cylinders.
