Abstract

We demonstrated optical elements based on the sulfur copolymers (poly(S-r-NBD2) termed Polycalc) for the IR optics applications. The high refractive index, excellent transparency in the IR wavelength region, and good moldability enable compact lens packaging and freeform designs. The advantages of organic-based polymers such as the lightweight, ease of fabrication, and cost-effectiveness are suitable for high volume commercialization. The chemical stability, water resistance and CTE of Polycalc are superior to conventional optical polymers. The demonstrated heat resistance after cycling to typical solder reflow temperatures shows that the Polycalc lens is feasible for wafer-level IR optics module including image sensors integrated with IC packaging.
