Abstract
An optical device including a holder and a light transmissive plate is provided. The holder includes a first frame and a second frame connected to each other, and the first frame is located inside the second frame. A light transmissive plate is disposed inside the first frame and has a surface. The first frame has at least one inner surface and includes at least one surface supporting part, and the surface supporting part extends along a direction from the inner surface of the first frame to the center of the first frame, and the surface of the light transmissive plate is at least partially supported by the surface supporting part of the first frame. The surface supporting part is non-continuously distributed along the inner surface of the first frame. The disclosure further provides a projector including the optical device.
