Abstract
An optical module includes a curved reflecting component, a first filtering component, a second filtering component and a rolling component. The curved reflecting component has a focus, a transmissive portion, a first reflecting portion and a second reflecting portion. The rolling component includes a first transforming portion and a second transforming portion. The first waveband light is transmitted into the transmissive portion and is then transformed into a second waveband light via the first transforming portion. The second waveband light is subsequently transformed into a first emergent light. The first waveband light is transmitted into the transmissive portion and is then transformed into the second waveband light via the second transforming portion. The second waveband light is subsequently transformed into a second emergent light.
