Application of Aspheric Collimating Lens/ Focusing Lens in Laser Collimation
Posted on:
2022-10-25
Aspheric Collimating Lens/ Focusing Lens plays a very important role in the optical system. For example, most of the mobile phone lenses, camera lenses, and ultra-short-throw projectors we have come into contact with. In such complex systems, the system aberration is mostly optimized by using a combination of multiple aspheric and spherical mirrors, and no standardized products have been formed.
Another important application of Aspheric Collimating Lens/ Focusing Lens is in laser collimation, focusing, laser and fiber coupling. The beam directly coming out of the laser is usually a Gaussian beam. In practical applications, such as optical measurement, laser medical treatment, laser processing and other fields, the laser beam needs to be shaped such as collimation, focusing, and homogenization. Conventional methods of collimation through spherical lenses usually require at least 2 lenses.
Since the laser is a single-wavelength light source, spherical aberration is often a factor that prevents a single spherical lens from obtaining diffraction-limited performance when focusing or collimating light. The single-chip Aspheric Collimating Lens/Focusing Lens optimizes spherical aberration perfectly to solve this problem. Therefore, it is often used to collimate the output light of optical fiber or laser diode, couple laser light into optical fiber, etc.
In the fields of industrial processing, optical measurement, laboratory research, etc., the wavelength, divergence angle, collimated beam diameter and other parameters of commonly used laser light source and fiber light source are relatively clear. Therefore, Aspheric Collimating Lens/ Focusing Lens manufacturers also aim at these applications Design and produce a series of precision polished large-diameter Aspheric Collimating Lens/ Focusing Lens and precision molded glass aspheric lens with excellent performance, which are widely used in laser collimation, focusing, laser and fiber coupling and other fields.
