中国计量科学研究院与北京精密激光仪器厂最近合作推出第四代双频激光干涉仪。它是不断改进、不断创新中诞生的新一代激光测量仪器。该仪器主要用于测量长度(0～60m),配上附件还可用于小角度、直线度、垂直度、平面度等测量,是一种多功能、准确度高的仪器,广泛适用于机械、电子、船舶、航空等行业。对线纹尺、光栅、磁尺、感应同步器的检测更为方便。该仪器采用美国Uniphase全内腔激光管作光源,使用寿命达1.2万小时,所用的稳频和微
China Institute of Metrology and Beijing Precision Laser Instrument Factory recently launched the fourth generation dual-frequency laser interferometer. It is a new generation of laser measuring instruments that are constantly being improved and innovated. The instrument is mainly used for measuring length (0 ~ 60m), with accessories can also be used for small angle, straightness, verticality, flatness and other measurements, is a versatile, high accuracy instruments, widely used in machinery, Electronics, shipping, aviation and other industries. On the ruler, grating, magnetic scale, induction synchronizer detection more convenient. The instrument uses the United States Uniphase full cavity laser tube for light source, the service life of 12,000 hours, the use of frequency stabilization and micro
