DJ_6光学经纬仪望远系统的透过率和光漫射率(简称杂散光)对望远镜成象质量起着重要作用。我厂生产DJ_6光学经纬仪有近二十年的历史,也是全国六秒级经纬仪主要生产厂家之一。望远系统经三次设计改进,成象质量有很大提高。但距机械工业部部标和国际名牌产品的透过率和光漫射率指标,还有很大的距离。针对仪器的望远镜进光量少、亮度小、成像质量不够理想,以致使得鉴别率下降等
DJ_6 Optical Theodolite The transmission and optical diffusivity of telescopic systems (referred to as stray light) play an important role in the imaging quality of telescopes. I plant production DJ_6 optical theodolite has nearly 20 years of history, but also the country’s six-second theodolite one of the major manufacturers. The telephoto system has been improved by three designs and the image quality has greatly improved. But from the Ministry of Machinery Industry standard and international brand-name products of transmittance and light diffusion rate index, there is a great distance. Telescope for the instrument into the light less, less brightness, image quality is not ideal, so that the identification rate decreased
