JDS-1立式接觸式干涉儀
本儀器是一種采用量塊或標(biāo)準(zhǔn)零件借以高精度的比較方式的立式精密長度計(jì)量儀器。主要用于150mm以下塊規(guī),亦可用作高精密度的長度和外徑的精密測量,是各級計(jì)量室的基本長度計(jì)量儀器之一。
JDS-1 Interferometer is applicable for measurement of 3-4 grade gauge blocks or precision sizes up to 150 mm by high-precision comparison with a higher grade of gauge block or a standard reference component. It is one of the basic length-metrological instruments.
