Precision Aspheric lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing output of a laser diode.
Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses also reduce the number of components in a multi-component system thus reduce the weight, increase throughput and simplify assembly.
For large quantity and relatively lower precision requirement production, molding provides one of the most cost-effective way of manufacturing of aspheres.
Shanghai Optics use plastic material and several different glass materials that are suitable for precision molding due to their low transformation temperatures. Acrylic, Plastic, BK-7, B270, Pyrex, Borosilicate, F2 etc.

Sometimes the many challenges that optics manufacturers have had to overcome while polishing glass aspheric surfaces have left designers with little confidence that precision glass aspheres can be manufactured in volume production, with tight specification, with a reasonable budget and in a short lead-time.
Over the past decade our understanding of technology and the polishing process has lead to the emergence of “new tools and manufacturing method” which make it possible for us to routinely produce a wide variety of sophisticated high precision aspheres. At Shanghai Optics we take pride in our ability to produce cost-effective high precision glass aspheres that provide our customers the competitive advantage for their custom applications.
