An apparatus for testing image sensors is provided. The light beam emanating from a light source is transformed into a diffused light beam by a beam diffuser and then cast on the sensing area of a tested image sensor. In this manner, although the test light beam coming from a certain direction is obstructed by the spots on the transparent cover and therefore fails to reach one point on the sensing area, the test light beam coming from other direction can still reach that point. Accordingly, the shadows of the spots on the sensing area are not clear; the accuracy of testing the image sensor can be greatly improved.
