Abstract

Method for producing an objective, in which the outer mounting includes an outer surface that is, at least in sections, limited by a plane which extends inclined toward the optical axis or which extends at a distance from the optical axis.

Claims

1. Method for producing an objective, an outer mounting of which has an outer surface that is limited, at least in sections, by a plane which extends at one of inclined toward the optical axis and at a distance from the optical axis, and in which the method the steps comprising:

a) the outer circumference of at least one lens for the formation of a surface lying in the plane is machined;

b) an inner mounting for the lens for the formation of a surface lying in the plane is machined;

c) the at least one lens is inserted in the inner mounting, and the outer surface of the inner mounting with at least one inserted lens is machine finished for fitting the at least one lens to the outer mounting of the objective; and

d) the machine finished inner mounting is inserted into the outer mounting.

2. Method according to claim 1, wherein:

a) the inner mounting and the at least one lens is finished using a machining method.

3. Method according to claim 2, wherein:

a) the at least one lens is retained in the inner mounting with a positive fit.

4. Method according to claim 3, wherein:

a) the at least one lens is retained in the inner mounting with an adhesive.

5. Method according to claim 1, wherein:

a) the at least one lens is retained in the inner mounting with an adhesive.

6. Method according to claim 1, wherein:

a) the inner mounting includes inner mountings, and the at least one lens is finished using a machining method.

7. Method according to claim 6, wherein:

a) the at least one lens is retained in the inner mountings with a positive fit.

8. Method according to claim 7, wherein:

a) the at least one lens is retained in the inner mountings with an adhesive.
