立式光學(xué)計(光學(xué)比較儀)|LG-1
本儀器是一種采用量塊或標(biāo)準(zhǔn)零件與試件相比較的方式測量物體外形尺寸的儀器。主要用于五等精度量塊,一級精度柱型規(guī)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.
