...Yih-Tun Tseng; Shu-Ming Chang; Sheng-He Huang; Wood-Hi Cheng This work presents a novel lensed plastic optical fiber (POF), efficiently coupled with a light source. A convexo-concave plastic lens (CCPL) was bound to a flat-end plastic optical fiber using laser transmission welding (LTW) to form...

...Fei Wang; Yang Chen; Fritz Klocke; Guido Pongs; Allen Y. Yi Compression molding is an effective high volume and net-shape fabrication method for aspherical lenses and precision glass optical components in general. Geometrical deviation (or curve change as often referred to in industry) incurred...

..., residual stresses frozen inside molded glass lenses under different cooling conditions were investigated using both experimental approach and numerical simulation with a commercial finite element method program. In addition, optical birefringence method was also employed to verify the residual stress...

.... Therefore, it is desirable to have a method that can perfectly trace skew rays, thus enhancing the performance of designed systems. Examples of optical elements possessing spherical boundary surfaces are plano-convex and plano-concave lenses, and bi-convex and bi-concave lenses. The parametric form...
