显微镜是有着漫长发展史的经典光学仪器之一, 它的性能在不断提高, 但显微物镜工作距离短在很大程度上限制了其应用。随着市场对长工作距离显微镜的迫切需求, 其研发将具有重要意义。本文根据设计要求, 初定物镜结构, 然后利用 ZEMAX进行设计、优化, 给出了一工作距离 150 mm、线视场 0.8、放大倍率 5倍、分辨力 6 μm的折射式以及折反射式显微物镜的设计结果, 并对比了二者的优缺点。

The microscope is one of the classical optical instruments with long development history. Its performance continues to increase, but the microscopic objective short working distance largely limits its application. As the market demand for long distance microscope, its development has important significance. According to the design requirements, determine objective structure firstly, and then use ZEMAX for design and optimization. A working distance of 150 mm, line 0.8, 5 times of magnification, resolution of 6 μm reflecting and catadioptric microscope objective design results are given. The advantages and disadvantages of the two results are compared.
