Abstract: The underlying objective is to create an optoelectronic sensor system which illuminates the specimen homogenously and only allows produced fluorescent light to reach the photoactive layer. The objective is achieved substantially by creating a total reflection layer for the introduced light before or above the optoelectronic sensor layer. This can be applied in all fields in which microarray biochips are used.
