AI驱动的设计应用
在本次难得的深度访谈中,我们有幸与屡获殊荣的设计专家约翰·罗杰斯博士展开交流。作为工程服务团队的核心成员,约翰博士详细阐述了 CODE V 中革命性功能“玻璃专家”的设计理念。凭借其数十年的专业经验,他深入解析了“玻璃专家”如何以卓越的精度将复杂的光学设计转化为实际应用,为行业带来了突破性的进展。
"What was the motivation for developing Glass Expert?"
CODE V can optimize glass types by treating the index and Abbe values as continuous variables. However, the challenge lies in converting these "fictitious" glasses into real glass types. The difficulty is that other properties of optical glasses (like secondary dispersion, CTE, and dn/dT value) do not vary continuously with index and Abbe.
"How were these challenges addressed before Glass Expert?"
Previously, we varied the glasses in a continuous manner and then selected the real glass that most closely matched the index and Abbe values of the "fictitious" glass. This method often led to sub-optimal performance as it ignored the non-continuous variation of other glass properties.
"What specific design challenges does Glass Expert solve that prior solutions don't?"
Our Engineering Services group has extensive experience in making glass choices, designing complex optical systems, and studying the properties of optical glass. This expertise enabled us to develop an algorithm that makes intelligent choices about which glasses to use, addressing challenges that previous methods could not.
"Can you share an anecdote where Glass Expert solved a complex design problem?"
Soon after its implementation, Glass Expert was used by a well-known optical design house to design a very wide-angle (nearly fisheye) lens that needed to be extremely well-corrected for lateral color. Initially, we anticipated a long process, but overnight, Glass Expert found a solution that met all the design goals. The customer was thrilled and began revising the design goals upward to see how much better the design could be made.
"How has Glass Expert changed the way you approach your design workflow?"
The most immediate change is that Glass Expert can accomplish in a few hours what a highly experienced designer could achieve in a week or more of hard work. Although it was conceived as a tool for improving the secondary color of an optical system, we have also found that, when used with Multiple Environmental Coupling (MECo), Glass Expert excels at athermalizing optical systems as well.
“研发玻璃专家的初衷是什么?”
CODE V 可通过将折射率和阿贝系数视为连续变量来优化玻璃类型。然而,关键挑战在于如何将这些“虚拟”玻璃映射为实际可用的玻璃类型。难点在于光学玻璃的其他特性(如二级色散、热膨胀系数及折射率温度系数)并不随折射率和阿贝系数呈现连续变化规律。
“在玻璃专家出现之前,您是如何应对这些挑战的?”
以往的方法是通过连续调整玻璃参数,并选择与“虚拟”玻璃的折射率和阿贝系数最为接近的实际玻璃材料。然而,这种方法往往导致性能欠佳,因为它未能充分考虑其他玻璃特性的非连续性变化。
“玻璃专家解决了哪些具体设计难题,而这些问题此前的解决方案无法有效应对?”
我们的工程服务团队在玻璃选型、复杂光学系统设计以及光学玻璃特性研究方面积累了丰富经验。基于这些专业知识,我们开发了一种智能算法,能够根据设计需求精准选择合适的玻璃类型,从而成功解决了传统方法难以克服的技术瓶颈。
“能否分享一个玻璃专家成功解决复杂设计问题的案例?”
在玻璃专家投入使用后不久,一家知名光学设计公司利用该工具设计了一款超广角(近乎鱼眼)镜头,该镜头需要对横向色差进行极高精度的校正。起初,我们预计这将是一个耗时较长的过程,但玻璃专家在一夜之间便找到了满足所有设计目标的解决方案。客户对此感到非常满意,并进一步调整设计目标以探索更优的设计潜力。
"玻璃专家如何改变了您的设计工作流程?"
玻璃专家的引入显著提升了设计效率,能够在短短几个小时内完成过去需要一位资深设计师花费一周甚至更长时间才能完成的任务。尽管最初它被设计为一种用于改善光学系统次级色散的工具,但在与多重环境耦合(MECo)结合使用时,玻璃专家还展现出卓越的光学系统无热化能力。
