Patent ID: 7327005

Claim:
An optical semiconductor module comprising: an optical semiconductor component having a front face including an optical sensor and front electrical terminals; encapsulation means, delimiting a cavity in which the optical semiconductor component is disposed, having external electrical connection means of the optical semiconductor component, the optical sensor being carried by the encapsulation means; a window allowing light to pass therethrough toward the optical sensor; a single optical focusing lens disposed in the cavity, between the optical sensor and the window, the single optical focusing lens having a lens diameter; a ring for supporting the single optical focusing lens at a substantially unadjustable distance from the single optical focusing lens to the optical sensor, wherein the ring is fixed on a part of the front face of the optical component that extends between the optical sensor and the front electrical terminals, wherein the ring is carried directly by the front face of the optical sensor, wherein the ring is a different structure from, and not fixed to, the encapsulation means, and wherein the ring has a ring diameter; and wherein the lens diameter is approximately equal to the ring diameter.
