Title :
Practical low-loss lens connector for optical fibres

Abstract :
A connector is described in which two lenses make a 1-1 image of the emitting fibre end upon the receiving end. This type of connector is not sensitive to surface contamination, radial offset and separation. It contains no high-precision components and the prealignment procedure is very simple. Average losses of 1.0 dB were obtained, which can be improved to 0.65 dB if antireflection coatings are used.
