Cam"e*ra lu"ci*da (?). [L. camera chamber + L. lucidus, lucida, lucid, light.] Opt.

An instrument which by means of a prism of a peculiar form, or an arrangement of mirrors, causes an apparent image of an external object or objects to appear as if projected upon a plane surface, as of paper or canvas, so that the outlines may conveniently traced. It is generally used with the microscope.
