Abstract

A microlens holder for supporting at least one microlens in alignment with a light source is described. Each of the microlenses has a radius and a back focal length varying linearly with the radius. The microlens holder includes a base having at least one V-groove therein for receiving the at least one microlens, each of the V-grooves having a pair of side walls, both side wall s being tilted by an angle 8 relative to the plane of the emitting light sourc e. The value is defined by the relationship cos(8) _ (1 + k)-1, where k is a positi ve constant factor associated with the at least one microlens. The microlens holder allows auto-focussing of the light source, independently of the exact diameter of the microlenses mounted in the holder. The optical alignment of the microlenses is made easier as well.
