Achromatic lenses are commonly used for colour correction to minimize or eliminate the colour aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for various applications such as detection or spectroscopy. Achromatic lenses can create smaller spot sizes compare with singlet lenses. Grand Unified Optics offers achromatic lenses with various AR coatings suitable for your application.
