1. An optical system for use with an endoscope, the optical system comprising:
a distal optical assembly comprising at least one fixing member and one or more optical lenses; and
a proximal optical assembly comprising:
a prism; and
a holder comprising a holder body having an exterior surface, the exterior surface comprising:
a cavity having a bottom and one or more walls extending from the bottom, the prism being disposed in the cavity; and
at least one fixing surface configured to fix the holder body to the distal optical assembly by a soldered connection between the at least one fixing member and the at least one fixing surface, the at least one fixing surface being separate from the cavity;
wherein a material of the holder body is a base material that is provided with a coating, a material of the coating having better solderability than the base material, the coating being removed from the cavity to expose a surface of the cavity, the exposed surface being blackened by a laser-assisted surface treatment; and
the at least one fixing member is separately formed from the at least one fixing surface with the coating arranged between the at least one fixing member and the at least one fixing surface.
