A method of forming a lens array block, the method comprising:
- (a) providing a backing plate having a surface;
- (b) forming on the surface of the backing plate, a first mask pattern comprising an array of first solid circles;
- (c) depositing by electrolysis, lens barrel material around the first solid circles to form a first lens barrel level containing a plurality of first holes;
- (d) forming on the surface of the first lens barrel level, a second mask pattern comprising an array of second solid circles;
- and
- (e) depositing by electrolysis, lens barrel material around the second solid circles to form a second lens barrel level containing a plurality of second holes, each second hole having a common central axis with a first hole.
