The self focusing collimating lens is mainly suitable for the connection of divergent beams of light, and it is usually used for the connection between fibers in optical passive devices. Advantages: Small size, easy assembly, and good collimation performance, mainly used in fiber collimators, fiber couplers, optical isolators, optical switches, WDM, DWDM devices
What is the difference between some collimating lenses and general lenses, which means that the output light of a general lens is also parallel and collimated when the light source is placed at the focal point.. So what are the greater advantages of collimating lenses compared to regular lenses.
In fact, a collimating lens is composed of several lenses. If it is an integrated product, its performance and stability are definitely better than those built with ordinary lenses. In addition, not all divergent beams need virtual focus, and the Gaussian beam of the laser has no focus.
