Abstract
An optical module used in a projection device is provided. The optical module includes a base and a filter mirror. The base has an inclined leaning surface and a sidewall surface. The sidewall surface is located at a periphery of the base and forms a through hole along a direction. The inclined leaning surface is extended from the sidewall surface and an inclined angle is formed between the inclined leaning surface and the direction. The filter mirror is disposed on the inclined leaning surface.
