北京计量光学仪器厂的全体革命职工,遵照毛主席“自力更生、艰苦奋斗”的伟大教导,克服了设备简陋、技术条件差等困难,敢于创新,敢于攀登科学技术的高峰,虽然建厂才二年多,就在原 DX_1 型大型工具显微镜的基础上,试制出了采用光栅数字显示技术的新型计量光学仪器。方便了读数、并消除了人眼读数的主观误差,在我国计量光学仪器上又迈出了可喜的一步。仪器用途:
All revolutionary workers of Beijing Metrology Optical Instrument Factory, following Chairman Mao’s great teaching of “self-reliance and hard work”, overcame the difficulties of simple equipment and poor technical conditions, dared to innovate, and dared to climb the peak of science and technology. On the basis of the original DX_1 large-scale tool microscope, a new type of metrology optical instrument adopting grating digital display technology has been tried out. Convenient for the reading, and eliminated the subjective error of the human eye reading, taking another gratifying step on the measuring optical instrument in our country. Instrument use:
