Description
Introduction of Bote Achromatic Doublet Lens
Achromatic doublet lenses, as the name suggests, are composed of two lenses bonded together. In addition to being achromatic, BOTE achromatic doublet lenses can also correct spherical aberration, and BOTE provides an outer diameter range of 10mm-100mm and a focal length range of It is a double cemented achromatic lens DLB of 20mm-1000mm, which can basically meet most of the daily needs of users.
In addition, if there are needs other than standard products, BOTE can provide customized services
Application
BOTE achromatic doublet lenses can be used as telescope objective lenses or collimating lenses for laser experiments.
In addition to chromatic aberration, spherical aberration has also been well corrected, so BOTE achromatic doublet lenses are very suitable as laser collimation lenses.
In addition to the chromatic aberration of on-axis object points, off-axis coma or astigmatism is also well corrected. Achromatic doublet lenses can be used in imaging systems such as telescope objective lenses or microscope imaging lenses.
Feature of Bote Achromatic Doublet Lens
BOTE double cemented achromatic lens is a cemented lens composed of two lenses with different refractive index and dispersion. Compared with a spherical single lens, it can correct chromatic aberration and spherical aberration.
By optimizing the lens design, the focal length is almost constant throughout the visible spectrum.
