An achromatic lens, also known as a doublet lens, is a type of lens designed to reduce chromatic aberration. It is a lens consisting of two cemented elements made of different materials. Chromatic aberration is a phenomenon in optics where different colors of light are focused at different distances, causing color fringes and blurring in images. The achromate lense offers superior correction of spherical aberration in monochromatic applicaitons. 


MOK Optics produces various of achromatic lenses with AR coating, the wavelength range from UV-VIS-NIR.
