Standard achromatic doublet lenses cover two ranges – the visible (400 – 700 nm) and near-infrared (700 – 1050 nm). Single-line, dual-line and broadband configurations different from standard ones are also available.

Cemented achromatic doublet lenses are optimized to provide excellent chromatic and spherical aberration-free performance. An optimized composition of two lenses in which one is made of dense flint and the other of crown glass, ensures a much smaller focus than singlet spherical lenses because of minimized longitudinal and transverse spherical aberrations. They also feature a nearly constant focal length across a wide range of wavelengths.
