LDM长距离显微镜

LDM long-distance microscope

长距离显微镜破除了只能近距离观测的传统，使微观观测可在高温、高压、有腐蚀气体的环境中进行，可广泛用于材料微观观测、化工、医学、司法鉴定等各个领域，本文着重介绍中科院上海天文台研制成功的ＬＤＭ－Ⅱ型长距离显微镜光学、机械结构特点及各种性能指标，用户正利用其独特的功能从事各种不同领域的工作。

Long-distance microscope overcomes the state of the conventional instruments. It can do microscopic observation in high temperature, high pressure and corrosive gas environment. It can be used widely in the materials microscopic observation, chemical industray, medicine,judicial judge etc.This paper deals briefly with the main characteristics and the optical, mechanical features of the LDMⅡ long-distance microscope made by Shanghai Observatory Academia Sinica. The user is engaged in a lot of research work with this instrument.
