KOSMOS油耦合摄谱仪镜头设计
Design of the KOSMOS oil-coupled spectrograph camera lenses
摘要：
介绍了KOSMOS摄谱仪用油耦合透镜组的设计细节。油耦合组件以独特的方式使用硅橡胶O形圈，以精确地将具有高径向和轴向刚度的镜头元件置于中心，同时还允许轻松组装。O形环可将油牢固地密封在透镜间隙内，以防止油迁移。描述了用于补偿由于温度变化引起的膨胀差的膨胀隔膜的设计。讨论了透镜组件、透镜间隙匀场、充油和排油、气泡缓解、材料兼容性、机械检查和光学测试等问题。
英文摘要：
We present the design details of oil-coupled lens groups used in the KOSMOS spectrograph camera. The oil-coupled groups use silicone rubber O-rings in a unique way to accurately center lens elements with high radial and axial stiffness while also allowing easy assembly. The O-rings robustly seal the oil within the lens gaps to prevent oil migration. The design of an expansion diaphragm to compensate for differential expansion due to temperature changes is described. The issues of lens assembly, lens gap shimming, oil filling and draining, bubble mitigation, material compatibility, mechanical inspection, and optical testing are discussed.
