| 摘要 |
An imagery system for a biochip (10) which comprises an approximately plane support, and a plurality of spots on an upper face (11), on which biochemical elements (12) are arranged, comprises a source (20) of a light beam to illuminate said upper face of the biochip and a device (30) for detecting radiation emitted by said upper face. The source and/or the detection device have good selectivity at at least one wavelength of interest (lambdai) within an ultraviolet radiation band. The biochip support has a reflectivity or transmission coefficient at said wavelength of interest for which the lower limit is of the order of 10 percent.
