We are proud to announce that Dr. Jiang Cheng from YEJIA Optical has published a groundbreaking research paper in the internationally renowned journal Applied Optics. Titled "Temperature-Induced Spherical Aberration in the Athermalization of Large-Aperture Glass–Plastic Optical Systems", this work explores temperature-related optical aberrations and presents innovative solutions for high-precision lens design. The paper was featured as the cover article of the May issue and is available online through the Optical Society's official publication platform:
On June 13, 2025, this publication was further recognized by the Optical Society of America (Optica) and selected as part of the "Spotlight on Optics"—a prestigious feature that highlights only 5–10 outstanding papers out of more than 600–800 monthly publications across Optica's 20+ leading journals, including Optica, Optics Letters, Optics Express, and Applied Optics.
In many advanced optical applications, achieving athermalization—ensuring the lens performance remains stable across temperature changes—is critical. Dr. Jiang and his collaborators from the Department of Optical Sources and Lighting Engineering at Fudan University have proposed a novel approach to managing temperature-induced spherical aberrations, especially in large numerical aperture (NA) plastic-optical systems.
Traditional athermal design methods often fall short when applied to plastic optics, where the thermal expansion coefficient and temperature-dependent refractive index have significant effects on imaging performance. Recognizing this, the team introduced a new compensating mechanism using the equivalent lens model. This method calculates the spherical aberration caused by each optical element due to temperature variations. By pairing optical elements that produce equal but opposite aberrations, these effects can cancel each other out, maintaining imaging accuracy even in harsh thermal environments.
The paper presents a real-world application of this model in the design of hybrid glass-plastic large-aperture lenses for automotive pixel lighting systems, offering a powerful tool for optical engineers seeking to overcome thermal challenges in modern lens development.
At YEJIA, we specialize in custom silicone optical lenses, molded silicone optics, and advanced optical system components. Our team of experts is constantly exploring material science and optical innovation to deliver high-performance solutions for LED lighting, automotive optics, medical devices, and other demanding applications.
We congratulate Dr. Jiang on this international recognition and remain committed to pushing the boundaries of silicone-based optical technologies.
