Optical Achromatic Lens
The Achromatic Lens consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. It is designed to cancel chromatic aberration at two wavelengths, eliminating focal length shifts across visible wavelengths.

Product Overview
Precision Achromatic Lens
This achromatic lens is engineered to eliminate chromatic aberration by combining a positive low-index Crown Glass element with a negative high-index Flint Glass element. Designed to provide consistent focal length across visible wavelengths, it effectively minimizes spherical aberration and coma for superior image quality. These lenses are ideal for high-precision applications such as diffraction-limited laser beam focusing, microscopy, and complex imaging systems.
