What Is a Lithography Lens? A lithography lens is a high-precision optical system used in photolithography machines — critical tools in semiconductor and microfabrication industries. These lenses are designed to project and reduce photomasks onto silicon wafers with nanometer accuracy, enabling the production of integrated circuits, MEMS, and nanostructures. A lithography lens typically consists of a complex multi-element assembly, often including aspherical lenses, diffractive optical elements, and high-refractive index materials, all precisely aligned to minimize optical aberrations and achieve diffraction-limited resolution. Lithography Lens Manufacturing: Challenges and Techniques The fabrication of lithography lenses involves extremely tight tolerances in design, machining, and assembly. Key manufacturing processes include: Ultra-precision grinding and polishing of optical surfaces Aspheric surface generation and…

Since our founding in 2010, we have been dedicated to the precision manufacturing of optical components. In 2018, we expanded our capabilities by establishing an R&D department focused on optical design, lens assembly, and the integration of opto-mechanical-electrical systems. As part of our commitment to sharing knowledge and supporting our clients, this article explores the key differences between industrial lenses and consumer camera lenses. Introduction Lenses are at the heart of all imaging systems, but not all lenses are created equal. While consumer camera lenses are designed for everyday photography, industrial lenses are engineered for high-performance imaging in rigorous environments. Understanding the difference between these two types of lenses is critical for selecting the right…

Introduction Infrared (IR) lenses are essential components in many modern optical systems. Unlike visible light lenses, IR lenses are designed to focus and transmit infrared wavelengths, making them essential in military, security, medical, and industrial applications. In this article, we’ll take a closer look at how IR lenses work, and how to assemble and integrate infrared lenses into optical systems. Such as night vision devices, hunting scope and sight, and low-light imaging systems. What is an Infrared (IR) Lens? An infrared lens is a optical component that focuses and transmits infrared light (wavelengths beyond 700 nm). Rather than using standard glass, the material of IR lenses are  Germanium (Ge), Silicon (Si), Zinc Selenide (ZnSe), and Calcium…
