Glass Achromatic Lenses, Color : Transparent for Optical Applications

An achromatic lens is a compound lens that is designed to correct for chromatic aberration. Chromatic aberration is an optical effect that occurs when light passes through a medium, such as a lens, and is bent at different angles based on its wavelength. This results in different colors of light being focused at different points, which can cause blurriness and other distortions in the image.
