摘要
Fiber optic interface modules and assemblies using same are disclosed, wherein the modules and assemblies are tolerant to misalignment and have a high coupling efficiency. The module has at least one lens that defines a folded optical path through the module body. The folded optical path is formed by total internal reflection within the module body from an angled wall of the module. The lens has an aspheric front surface and a planar rear surface and is configured to have an optimum tolerance to a lateral misalignment relative to a light source while maintaining a high coupling efficiency between the light source and an optical fiber.
