Adhesives Used to Improve Optical Lenses

Posted By ASC, Thursday, December 10, 2015

Micro-optics, a development that was first introduced in mobile phone cameras in 2007, are now used for a variety of applications. These include LED flash modules, infrared sensors, ambient light and proximity sensors as well as cameras.


Optical wafers consisting of multiple small lenses are used to manufacture devices using micro-optic technology. Crystal clear adhesives are used in the assembly of these optical wafers, and together with the lenses, adhesives are helping to improve quality while reducing costs. The adhesives allow manufacturers to attach a large number of optical and optoelectronic components to each glass wafer.


This technology allows for greater image quality through reduced pixel sizes, and the UV-curing adhesives offer excellent optical clarity while withstanding temperatures of up to 260°C and tolerating humid environments. Today, high-power Fresnel lenses are manufactured using optical adhesives.
