Abstract: A method for manufacturing a camera module. The method includes: a) mounting an image sensor on a circuit board, b) inserting and fixing the circuit board into a housing, c) aligning an objective lens accommodated in the housing and including an electrical interface with respect to the image sensor, d) fixing the objective lens in the housing. In step b) spring contacts, which are movable with respect to the circuit board, are inserted into the housing together with the circuit board and, in a step e), i.e., after the fixation of the objective lens in the housing, are brought into contact with the electrical interface with the aid of clamping and/or fixing elements.

Abstract: The invention relates to an energy filter image generator for filtering electrically charged particles. The inventive energy filter comprises at least two toroidal energy analysers (30, 40) arranged one inside the other. A transfer lens device (20) is disposed between the plane of emergence (5) of the first energy analyser (30) and the plane of incidence of the second energy analyser (40), thereby making it possible to obtain the perfect energy filtered reproduction of the surface (1?) of a sample on a detector (10).
