Achromatic doublet lens Optosigma Corporation

These are cemented achromats with a very precise range of tolerances and specifications. They are extremely convenient general purpose lenses. Being cemented they do not need a lens cell and can be treated as an individual component.

These lenses can be used as collimators, focusing lenses or light collectors. Optimized for use at three wavelengths, 486.1, 546.1 and 656.3nm, these lenses perform well throughout the visible spectrum. They have a minimum of spherical and chromatic aberration and perform well for all paraxial imaging tasks. These achromats are coated with a broadband Anti-Reflection coating to reduce surface losses in the visible region. Optional Anti- Reflection coatings for other wavelength regions are also available.
