Abstract

A hybrid Si-HDPE substrate was developed as an alternative to infrared (IR) lens material in 7.5 to 14 μm wavelength using high-precision molding press. HDPE was heated to melt state and pressed onto a Si wafer. Hybrid Si-HDPE with the thin laminated polymer improved IR characteristics of Si. The hybrid substrate then used as an IR lens for night vision camera and the images captured shows similarity to Si filtered images. These results show that hybrid Si-HDPE provide an effective solution for inexpensive IR lens with easy fabrication. Micro dimples can be precisely formed on HDPE for night vision systems lens.
