Optics & Technology

In infrared optical systems, material selection plays a critical role in determining transmission performance, imaging quality, and applicable wavelength ranges. Among various infrared materials, silicon (Si) is widely used in the mid-infrared region due to its excellent optical properties, mechanical strength, and cost-effectiveness. This article introduces the classification of silicon…

Dome lenses, also known as hemispherical lenses, are precision optical components shaped like half of a sphere. They are commonly used in optical systems where light needs to pass through a curved surface while maintaining high accuracy and minimal distortion. Structure and Design A dome lens typically has a curved…
