Abstract
There is provided a method for producing an optical system, whereby molds and coatings becomes embedded in the lens forming fluid, allowing the lens forming fluid to solidify.
Claims10
A method for producing an optical system, the method comprising the steps of, in order
- a) providing at least a first mold part to provide a first mold cavity for an intermediate product with a surface,
- b) providing a lens forming fluid in the first mold cavity, and allowing the lens forming fluid to solidify, to produce a solidified intermediate product with a surface,
- c) coating at least a part of the surface of the solidified intermediate product with a material to produce a functional optical element in the optical system, where the material is different from the lens forming fluid,
- d) providing at least a second mold part for the optical system,
- e) arranging the solidified intermediate product in relation to the second mold part to provide a second mold cavity such that the coating applied in step c) is exposed to the second mold cavity and
- f) providing lens forming fluid in the second mold cavity such that the functional optical element formed in step c) becomes embedded in the lens forming fluid, and allowing the lens forming fluid to solidify.
