Abstract
In one embodiment, an optical device having a convex lens, a concave lens and a mirror member is provided. The convex lens is arranged on an axis and has a convex surface at one side in a direction of the axis. The convex lens reflects a first wavelength light and transmits a second wavelength light. The concave lens is arranged on the axis and at the other side in a direction of the axis and having a concave surface. The mirror member has a reflective surface opposing the convex surface and is arranged apart from an outer circumference of the convex lens.
