Abstract
A projector is provided which can handle high light intensities without dust or foreign matter penetrating the inside of the apparatus and thus deteriorating the quality of the image projected. The projector apparatus comprises a spatial light modulator (SLM) unit provided with a plurality of reflective SLMs and a prismatic light splitting/combining unit. The SLM unit is enclosed in a substantially sealed chamber. A heat path for cooling each SLM is provided, whereby the heat path connection is through the wall of the substantially sealed chamber. In this way, heat energy from the main heat source inside the sealed chamber is brought outside the sealed chamber for dissipation.
