Low price Achromatic Doublet Lenses
Feb 24,2022
How much do you know about achromatic lenses? The Low price Achromatic Doublet Lenses editor will take you to a brief look.
Achromatic lenses can not only eliminate chromatic aberration, but also eliminate spherical aberration by appropriately changing the radius of curvature of each surface. If the two glasses that make up the doublet can be chosen arbitrarily, it can also eliminate coma at the same time.
There are also chromatic aberration corrections for three or four kinds of light, and the residual chromatic aberration is smaller at this time, but due to the difficulties in design and manufacture, such achromatic lenses are only used in some special occasions. Achromatic lenses are widely used, and a multi-lens optical system often consists of multiple achromatic lenses. High-quality microscope objective lenses, photographic lenses, etc. are all complex lens combination systems that eliminate both achromatic aberrations and other monochromatic aberrations.
The above is what the editor of Low price Achromatic Doublet Lenses tells: knowledge about achromatic lenses.
