Expanded aspherical lens aperturture contributes around 7% performance improvement in terms of coupling efficiency, this is based on high refractive index gl* and original nano machining process. ●Dielectric multilayered AR (Anti Reflection) coating will be cover from O-Band to L-Band which is popular wave length for optical communication, and optional for visible light. ●Compliant with RoHS 6. ●One side Au (Gold) plating is also optional, it's easy for brazing (soldering) *embly. Applications ●Optical communication modules ●Micro/pico projectors
