Optical limiter device, comprising a non linear limiter element, one first lens device and one second lens device, said first lens device is arranged to receive beams of electromagnetic waves and refract said waves, said second lens is arranged to essentially refract said waves in an essentially reverse manner, said non linear limiting element is arranged to be positioned in a position between said lens devices, this position being a conceivable focus of said first and said second lens device and said first lens device's focus is independently adjustable which, in use, provides for an optimal intermediate image substantial in a plane comprised in the non linear limiter element. An optical arrangement is also disclosed comprising an optical limiter device and an optical system. |
