Achromatic doublet lenses are focusing components to reduce chromatic aberrations from broadband light sources. Unlike singlet lenses, achromatic lenses have a constant focal length independent of aperture and operating wavelengths and have a superior off-axis performance. Our achromatic lenses are designed to minimize spherical aberration and coma when operating at infinite conjugate ratio, producing smaller focused spot sizes. These achromatic lenses are supplied with anti-reflection coatingS for the Visible wavelengths 400-700nm.
