Apparatus for obtaining an image of a specimen ( 6 ) by optical projection tomography comprises a confocal microscope ( 1, 2, 3 ) which produces a light beam which scans the specimen ( 6 ) whilst the latter is supported in a rotary stage ( 7 ). Light passing through the specimen is passed through a convex lens ( 8 ) which directs, onto a central light detector of an array of detectors ( 9 ), light which exits or by-passes the specimen parallel to the beam incident on the specimen.
