Fabrication of adhesive lenses using free surface shaping [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 Two approaches for fabricating polymer lenses are presented in this paper. Both are based on filling circular holes with UV curing adhesives. Initially, the viscous adhesive material creates a liquid and spherical free surface due to its own surface ...
