The newly developed quartz lens integrates the quartz window material and the lens with AGC’s proprietary technology so that a transparent adhesive is not required, avoiding degradation issues under ultraviolet light. In addition, the “special solder” developed by AGC is already overlaid so that OEMs can join lens and the LED cavity by simply heating and pressing the two parts in atmosphere, without large-scale de-oxygenation equipment. The proprietary solder is soft so as to ease the thermal stress due to the difference of CTE between package and window, so it will not crack or allow any air leak. Prototyping will begin from the third quarter of 2018, and mass production is scheduled to begin in 2019.
