Achromatic Doublet Lens

Achromatic Doublet Lens
Achromatic lenses are cemented with two lenses mainly used to reduced values of
spherical aberration, coma and chromatic aberration. Sunday offer positive
achromatic lenses and negative achromatic lens with coatings

Case Study
Axial and vertical color difference
Axial chromatic aberration arises from the difference in refractive index of
the same material for different wavelengths of light, resulting in varying
optical focal degrees.
While lateral chromatic aberration is caused by the different magnification
ratios of the same material for different wavelengths of light. In essence, all
of this is due to the different refractive indices of the same material for
different wavelengths of light.

The function of the double-coated lens
1. The core method for eliminating aberrations
2. The key design for correcting color differences
3. An important way to optimize the optical system
