Real-time polymerase chain reaction device, has monitoring device with electrical device for examining electrical function of light emitting diodes, where monitoring device generates signals when determining malfunction of diodes

摘要

The device has an illumination device emitting an illumination light (15) on samples. A detector (27) produces a signal that depends on the intensity of the light coming from the samples. A monitoring device (45) examines the function of the illumination device. The illumination device includes light emitting diodes (14) attached to the respective samples. The monitoring device includes an electrical device for examining the electrical function of the diode. The monitoring device is designed for generation of signals, when determining the malfunction of the diodes.
