Abstract
An exemplary image viewing system includes a display device configured to emit visible light representative of an image provided for display by the image viewing system, an infrared light source configured to emit infrared light, a viewing lens, and a black glass mirror provided between the infrared light source and the viewing lens. The black glass mirror comprises black glass and a coating on an outer surface of the black glass. The coating is configured to reflect a first portion of the visible light emitted from the display device towards the viewing lens, pass a second portion of the visible light emitted from the display device to the black glass, and pass a portion of the infrared light emitted from the infrared light source toward the viewing lens. The black glass is configured to pass the portion of the infrared light and absorb the second portion of the visible light.
