Building on the legacy
of US Precision Lens (a pioneer in plastic optics molding), Greenlight Optics
brings together decades of experience and advanced equipment to mold precision
plastic optics in-house.
molded plastic optics requires special knowledge and capability. Due to tight tolerances and often extreme
mold processing conditions, the injection mold designs and fabrication
techniques require special knowledge and skills. The injection molding equipment should have
advanced control capability and care must be taken to ensure cleanliness. The molding process parameters (temperatures,
pressures, and speeds) are unique to precision optics molding and these
processing parameters are generally a closely guarded trade secret. Greenlight’s molding equipment also includes
robotics, conveyors, custom degaters, thermolators, vacuum loaders, and
Greenlight uses Engel
all-electric Fanuc Roboshot molding machines to produce a variety of plastic molded lenses. Recent examples of lenses molded at Greenlight
includes: freeform lens arrays for LED
lighting, precision laser collimating lenses, CMOS imaging lenses for robotics
and medical devices, integrating tunnels, TIR lenses for LED illumination, and
a variety of plastic microlens arrays.
The engineers at Greenlight Optics are experienced in when and how to
take advantage of molded plastic optics.
