Abstract
A lens system for a camera objective has a plurality of optical lenses that are arranged one after another along an optical axis and are configured for imaging in the visually perceivable spectral range. At least a part of the optical lenses has two types of lens faces that intersect a beam path of the camera objective. At least three of said lens faces are provided with a first anti-reflective coating which has a larger reflectance in at least one partial region of the visible spectral range than a second anti-reflective coating of the remaining lens faces. In addition, a camera objective including the lens system and a method for producing a lens system are provided.

A lens system for a camera objective, the lens system comprising:
- a plurality of optical lenses arranged one after another along an optical axis thereby forming a beam path, and configured for imaging in a visually perceivable spectral range;
- at least a part of the plurality of optical lenses having lens faces which intersect the beam path of the camera objective;
- the lens faces forming a first group of lens faces and a second group of lens faces;
- the first group of lens faces including at least three of the lens faces and being provided with a first anti-reflective coating having a first reflectance in at least one partial region of a visible spectral range;
- the second group of lens faces being provided with a second anti-reflective coating having a second reflectance in the at least one partial region of the visible spectral range;
- the first reflectance being larger than the second reflectance.
