精密测角转台是一种高精度、多功能、数字显示的测角装置。其静态测角分辨率为0.01″,一次静态测量任意角的准确度为0.22″(峰-峰值)。动态检测圆光栅直径间隔的准确度为0.16″(峰-峰值)。
Precision goniometer turntable is a high-precision, multi-function, digital display angle measuring device. The static angular resolution is 0.01 “and the accuracy of any static measurement of any angle is 0.22” (peak-to-peak). The accuracy of circular detection of the diameter of the circular grating is 0.16 "(peak-to-peak).
