China Education Equipment Purchasing Network News: Recently, Alps Electric officially announced that it has successfully developed the "FLGS3 series" of aspheric glass lenses for optical communications supporting wide-angle laser diodes. An indicator of light transmission efficiency-light combining efficiency is increased from 68% to 73% of the original product. The external dimensions are 1.0mm × 1.0mm × 0.8mm, which is known as the smallest micro projector lens in the world.
Alpine Electric's FLGS3 micro-projector lens has started production and is expected to be shipped by the end of this year, with about 100,000 sales per month.
Alps Electric has officially announced the successful development of the "FLGS3 Series" aspheric glass lens for optical communications supporting wide-angle laser diodes.

The external dimensions are 1.0mm × 1.0mm × 0.8mm, which is known as the smallest micro projector lens in the world.
The glass lens is mainly used as an optical communication transceiver module for submarine cables and base stations. Among them, the aspheric glass lens is used to transmit the optical signal to the optical fiber in a low-loss manner. Recently, glass lenses have also been equipped with palm-sized mini projectors, and Alps Electric also plans to use this development for the consumer market.
Compare FLGS3 with ordinary pen
FLGS3 not only has the smallest size in the industry, but also expands the number of effective openings to 0.65 × 0.13 (0.5 × 0.1 for the original product). As a result, the optical coupling efficiency has increased to 73%. By improving the light combining efficiency, the loss of light can be reduced, and the light input can be reduced to obtain a specified light output. Therefore, power consumption can be reduced and heat generation can be suppressed. In addition, it is also suitable for high brightness applications in projectors.
A dielectric multilayer film was deposited on the surface of the glass lens by sputtering. By changing the dielectric multilayer film, in addition to the standard wavelength of 1260 to 1625 nm of the optical communication band, it also supports the visible band of 400 to 600 nm for micro projectors.
