JDS-1立式接触式干涉仪
本仪器是一种采用量块或标准零件借以高精度的比较方式的立式精密长度计量仪器。主要用于150mm以下块规,亦可用作高精密度的长度和外径的精密测量,是各级计量室的基本长度计量仪器之一。
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.
