全新 16 吋 f/3 Dobsonian 轻量化镜坯，专为海外观星计划设计。另计划推出最大至 40 吋之大型镜坯，欢迎联络查询供应情况。New lightweight mirror blank for a 16" f/3 Dobsonian for overseas stargazing programs. Larger blanks up to 40" are also planned. Please contact us for availability.
这镜材涉及很多应用科学，有限元设计、玻璃选料、建造熔炉、温度控制、造模、退火、研磨抛光，以至日后如何组装成望远镜等，单造一片镜的加热及降温退火电费都以港币千元计了。The production of this mirror substrate involves a wide range of applied sciences, including finite element design, glass material selection, furnace construction, temperature control, mold fabrication, annealing, grinding and polishing, as well as the subsequent integration into a complete telescope system. The electricity cost alone for heating and controlled cooling (annealing) of a single mirror blank runs into the thousands HKD.
