IdealPhotonics' optical lens is an optical element designed using the principle of light refraction. It is typically made of transparent materials (such as glass, plastic, or crystal) and has at least one curved surface (or a combination of a flat and curved surface). Its core function is to control the direction of light propagation, focal point, or imaging characteristics by changing the propagation path of light, thereby converging, diverging, or collimating it.By precisely controlling the behavior of light through geometry and material properties, it serves a wide range of fields, including imaging, illumination, and measurement. Its design requires a balance between functionality, performance, and cost, making it a cornerstone of modern optical technology.
