PCT No. PCT/GB95/02186 Sec. 371 Date Jul. 28, 1997 Sec. 102(e) Date Jul. 28, 1997 PCT Filed Sep. 15, 1995 PCT Pub. No. WO96/09548 PCT Pub. Date Mar. 28, 1996A system and method for conducting an optical inspection of a biological, chemical, or biochemical sample supported by an optical transparent disc. The disc is mounted for rotation about its central axis whilst a light source and detector are mounted on an arm for rotation in an arc crossing the surface of the disc. The source is arranged above the disc and the detector below the disc with the optical axes of the two being aligned so that the entire usable surface of the disc can be scanned by the light source and detector. The disc is provided with a calibration marking which interrupts the passage of the light beam when the beam passes over it, thus allowing the scan to be aligned relative to the disc. The optical properties of the sample supported on the substrate can be automatically and rapidly inspected by analyzing the output of the light detector.
