ABSTRACT:
A micro-optic lens is formed by making a lens element (20) having a length less than the required lens length. Adhesive (22) is attached to the rear of the lens element and a glass plate (21) attached to the adhesive. An optical fibre (26) is located against the plate (b 21), light is transmitted along the fibre, the beam emerging from the element (20) is sensed and the axial position of the plate (21) adjusted until the beam is sensed to be collimated. The adhesive (22) is then cured.
