ABSTRACT:
In one embodiment, a lens structure has an object surface, an image surface, and an axicon mirror. The axicon mirror is defined by an inner diameter, an outer diameter, and a tilt angle, with the tilt angle being defined by a plane of the axicon mirror and the surface of the axicon mirror. The image surface is positioned within the inner diameter of the axicon mirror. The lens structure may be incorporated into an optical transmitter having a light source and a photodetector. The light source is positioned to transmit light toward the object surface of the lens structure, and the photodetector is positioned to receive light reflected from the axicon mirror. A method for producing lens structures with different optical attenuation properties is also disclosed.
