Abstract
Reflections from an air-to-solid interface in a multiple reflector optical device are suppressed by giving the output surface of the device a slightly curved refractive surface so as to deflect the reflections away from the optical axis of the device. The device is shown in use as a transducer input/output device, and as a fiber-optic cable terminus and coupler.
