Aspheric Laser Lenses

Description

Introduction of Bote Aspheric Laser Lenses

Another important application of aspheric mirrors is in laser collimation, focusing, and coupling between lasers and optical fibers. The beam directly coming out of the laser is usually a Gaussian beam.

However, in practical applications, such as optical measurement, laser medical treatment, laser processing and other fields, the laser beam needs to be collimated, focused, homogenized and other shaping. Conventional collimation method through spherical lenses usually requires at least 2 lenses.

Since 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. A single-piece aspheric lens perfectly solves this problem by optimizing spherical aberration. Therefore, it is commonly used Used to collimate the output light of optical fiber or laser diode, couple laser to optical fiber, etc.

Application

In projection systems, aspheric lenses can be used to correct distortion of projected images to ensure a uniform and clear image on a large screen.

For example, it is used in projectors in movie theaters and projection equipment in conference rooms.

In terms of optical instruments, such as microscopes, telescopes, etc., aspheric lenses help improve imaging quality, allowing users to observe finer structures or more distant celestial objects.

In the field of laser processing, aspheric lenses can be used to focus laser beams and improve the accuracy and efficiency of laser processing, such as precise control of laser beams in laser cutting, laser welding and other processes.
