Alps Electric has developed the FLGS3
Series aspherical glass lens for optical communication in submarine
cables and base stations.
The FLGS3 Series lens has high optical
coupling efficiency and is compatible with wide-angle laser diodes, it
comes in a 1×1mm profile which the company says is the industry's
smallest. The manufacturer has expanded the effective numerical aperture
(NA) to 0.65×0.13 (from 0.5×0.1) while retaining the industry's
This raised optical coupling efficiency from 68% to 73%,
contributing to lower losses and lower power consumption. What's more,
the FLGS3 Series lens is made from lead-free glass, achieving compliance
with both RoHS 6 and REACH regulations. The lens is compatible with
standard optical communication wavelengths (1260nm to 1625nm) and a
visible light option is also available.
