Aspheric Lenses

Description

Introduction of Bote Aspheric Lenses

Bote Aspheric Lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode.

Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.

Bote Aspheric Lenses feature low f/#’s for optimum light gathering performance. Prescription data is available to easily integrate these aspheric lenses into an optical system. These lenses have also been computer optimized to eliminate spherical aberration while minimizing higher order aberrations.

VIS coating option provides less than 1.5% reflection from 425 – 675nm. NIR coating option provides less than 1.5% reflection from 600 – 1050nm.

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.
