Gauss lens
Encyclopedia
The Gauss lens consists of two lenses
; in its most basic form, a positive meniscus lens on the object side and a negative meniscus lens on the image side. The power
of the positive element predominates, but the negative element corrects for chromatic aberration

Lens (optics)
A lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the beam. A simple lens consists of a single optical element...

Optical power
Optical power is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device. The dioptre is the most common unit of measurement of optical power...

Chromatic aberration
In optics, chromatic aberration is a type of distortion in which there is a failure of a lens to focus all colors to the same convergence point. It occurs because lenses have a different refractive index for different wavelengths of light...
