초록 ▼

A semi-active laser (SAL) sensing system is thus provided that uses a lens concentrator system to pass received reflected laser light from an aperture to a detector. The lens concentrator system facilitates the use of SAL systems with different laser designator wavelengths to improve the performance of the SAL system. In one embodiment, the lens concentrator system is formed from polymer having substantial optical clarity for radiation having wavelengths between approximately 1.5 and approximately 1.65 μm. For example, the lens concentrator system may be formed from amorphous fluoropolymer. The lens concentrator system formed from amorphous fluoropolymer facilitates the use SAL designators using different wavelengths than those in past SAL sensing systems.
