<p>Apparatus for use in optical analysis of sample arrays comprises a video camera (10) which provides a video signal to a personal computer (9) and display apparatus (6), (30). An image of the sample array is stored in pixels and can be displayed in real time or can be manipulated by means of the personal computer (9), for instance by overlaying different images. The camera (10) is mounted parallel to a sample plate (16), for compactness, a mirror plate (44) being used to allow the camera (10) to view the sample array. The camera (10) has a relatively short focal length and correcting means (204) are provided to correct marginal defects of the image. Sample plates (16) are positioned with respect to the camera (10) by means of a locking mechanism (326). The apparatus finds particular application in optical analysis of fluid medical samples.</p> |
