1. An optical system for an endoscope, the optical system comprising:
a distal optical assembly;
a proximal optical assembly; and
at least one elongated bar-shaped fixing element;
wherein the proximal optical assembly is fastened to the distal optical assembly by the fixing element;
the proximal optical assembly comprises a first holder and a second holder each configured to receive an image sensor; and
the at least one fixing element comprises a first fixing element and a second fixing element, wherein each of the first holder and the second holder has a first fixing region and a second fixing region, the first fixing element fixes the distal optical assembly to the first fixing region of the second holder and to the second fixing region of the first holder, and the second fixing element fixes the distal optical assembly to the first fixing region of the first holder and to the second fixing region of the second holder.
