Achromatic Doublets

 

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 a simple 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 really well for all paraxial imaging tasks. These Achromats are coated with a broadband BMAR anti-reflection coating to reduce surface losses in the visible region. Optional anti-reflection coatings for other wavelength regions may also be specified from this coating selection chart.

Both inch and metric diameters are available.

Both inch and metric diameters are available.

Chromatic aberration is simply the result of optical materials having different indices of refraction at different wavelengths - and as a result the focal length of a lens will be slightly different for different colors. A bandwidth of 100nm or less will rarely produce problems. But when your operating range is much larger than this you really should use an achromat that has been designed for use in this region. Our high quality achromats are designed for use throughout the visible spectrum.
