The device can be calibrated so that the prism-rotating dial reads directly in wavelength . 这个装置可以经过校准,使得校镜旋转度盘读数直接用波长。
After completion of this task , the reading from the dial by traditional mechanic - contacted test can be replaced by the reading directly from the monitor of computer gauge comparator , and the precision is very high , under all conditions are satisfied in the laboratory , its precision can be as high as 0 . 01 u m 本课题的完成解决了传统的机械接触式测量只能从度盘读数,电脑量块比较仪可直接从电脑显示器读出结果,而且精度相当高,在实验室所有条件满足的情况下,精度可达0 . 01 m 。
