Optical assembly for a camera having an image sensor and method of manufacturing such an optical assembly

Claim 1

An optical assembly for a camera, comprising a colour-separation system having an entrance window and at least one exit window, and a solid-state image sensor which is fixed opposite the or each exit window, and which comprises an image-receiving surface accommodated in an envelope, characterized in that each solid-state image sensor is fixed to the exit window by means of a holder which comprises two holder plates having facing apertures and which are fixed to the exit window and the solid-state image sensor respectively, an elastically deformable element cooperating with and acting between the two holder plates, the holder plates being secured in a desired position relative to one another by fixation means.

Claim 8

A method of manufacturing an optical assembly comprising a colour-separation system for a camera, in which during a process step a solid-state image sensor is fixed opposite an exit window in an aligned position, characterized in that before the solid-state image sensor is fixed opposite the edit window, a holder is formed from a first and a second holder plate and an elastically deformable element provided between the holder plates, the holder plates being tiltable relative to one another by virtue of the elastically deformable element, the solid-state image sensor is fixed to the second holder plate, the holder with the solid-state image sensor is arranged over the exit window, a test pattern is displayed on the entrance window of the colour-separation system, the first and the second holder plates are tilted relative to one another until the image-sensor records a desired test pattern, and in that the two holder plates are secured to one another in an aligned position by means of a fixation element.

Claim 9

A method of manufacturing an optical assembly comprising a colour-separation system for a camera, in which during a process step a solid-state image sensor is fixed opposite an exit window in an aligned position, characterized in that before the solid-state image sensor is fixed opposite the edit window, a holder is formed from a first and a second holder plate and an elastically deformable element provided between the holder plates, the holder plates being tiltable relative to one another by virtue of the elastically deformable element, the solid-state image sensor is fixed to the second holder plate, the holder with the solid-state image sensor is arranged over the exit window, a test pattern is displayed on the entrance window of the colour-separation system, the first and the second holder plates are tilted relative to one another until the image-sensor records a desired test pattern, and in that the two holder plates are secured to one another in an aligned position by means of a fixation element.
