Metalenses, being composed of subwavelength phase-control nanostructures, can achieve
peculiar manipulations of incident rays. Dispersion is one of the key optical characteristics to …

Chalcogenide glass (ChG) is increasingly used in infrared optical systems owing to its
excellent infrared optical properties and scalable production using precision glass molding …

It is important to determine the ideal combination of housing materials, groups of refractive
materials, and their optical powers for athermalizing achromatic and apochromatic optical …

Subject of study. Automating the synthesis of “cemented doublet with a singlet” and “singlet
with a cemented doublet” objectives with an entrance pupil on the first surface of the system …

The common methods used for correcting chromatic aberration are typically based on multi‐
lens and multi‐material systems, resulting in lens thicknesses that are several orders of …

摘要为解决光学消热差技术镜片多且结构复杂的问题, 提出了一种两片式远距结构消热差光学
设计方法. 该光学系统由前折衍混合正透镜和后负透镜组成, 衍射面补偿系统的大部分色差和小 …

In this paper we propose a method for broadband achromatic and passive athermal optical
system design using a combination of three doublets. In the implementation of this method …

摘要(中) 鏡頭製造組裝公差是每一家鏡頭光學廠必需面對的問題, 但其加工成本與光學成像品質,
每家光學廠差異很大技術也不同. 本文為玻璃鏡片材料特性探討與鏡片製造和鏡頭組裝公差對其 …

We demonstrate two broadband multispectral infrared (3.5–11.5 μm), zoom (3×) systems
with focal lengths adjustable from 50 mm to 150 mm. Both systems are successful in meeting …

Abstract In this study Ge–ZnSe–Ge (spectral range 8–14 μm) and Si–Ge–Si (spectral range
3–11 μm) air-spaced photographic objective triplet lens designs are discussed. The two …
