Abstract

Techniques are disclosed for creating optical systems and assemblies that provide increased field of view (FOV) for light detection by coupling a flip-chip light sensor directly to a condenser lens. According to certain embodiments of the invention, an optical assembly can include a condenser lens with a substantially flat surface optically contacted with a substantially flat surface of a substrate of a flip-chip light sensor. The thickness of the substrate is such that the active area of the light sensor is disposed on a focal plane of the optical system. This enables accurate light detection and increased FOV over conventional techniques.
