LG-1 立式光学计
Vertical Optimeter
用途 Applications ：
本仪器是一种采用量块或标准零件与试件相比较的方式测量物体外形尺寸的仪器。主要用于五等精度量块，一级精度柱型规及各种圆柱形，球形，线形等物体的直径或板形物体的厚度的精密测量，对被测件作微小位移测量。亦可用来控制精密零件的加工。
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.
