兵器工业部于一九八五年四月十六日至十九日于北京主持了“透射式光学角规”科研成果技术鉴定会,参加会议的有来自中国计量科学院、航空工业部第三○四研究所、中国科院长春光机所等二十多个单位三十多名代表。鉴定会认为,由北京工业学院和国营云南光学仪器厂共同研制的透射式光学角规,是一种新的高精度小角度检测手段。它可用于各类自准直仪,经纬仪和分光仪秒盘等小角度测量仪器示值误差的检测,亦可检测二维示值误差。透射式光学角规在0～15′范围内偏向角
The Weaponry Industry Department hosted the Technical Appraisal Meeting of Scientific Research Achievements of “Transmissive Optical Geometry” in Beijing from April 16 to April 19, 1985 with the participation of experts from China Academy of Metrology, Aviation Industry Ministry III Four institutes, the Chinese Academy of Sciences Changchun Institute of light more than 20 units more than 30 delegates. Identification will think that by the Beijing Institute of Technology and state-owned Yunnan Optical Instrument Factory jointly developed by the optical angle gauge is a new high-precision small angle detection means. It can be used for various types of self-collimator, theodolite and spectrometer seconds and other small-angle measurement instrumentation error detection, can also detect two-dimensional indication error. Transmissive optical goniometer in the range of 0 ~ 15 ’deflection angle
