Abstract
The present invention relates to especially microfluidic analysis systems where the emitted light of a emitting source is measured by optic detection, and where a transparent body separates the emitting source from the optic detector. The invention especially relates to optic calibration of the device, the calibration being related to changes in the transparency of the transparent body and/or changes in the temperature of the emitting source.

1-15. (canceled)
An analysis device for analyzing fluids by optical detection of reactions in fluids, the analysis device having:
- a fluidic part comprising a fluid communicating network, where at least a part of the fluid communicating network has a transparent wall section, and a temperature responsive element having reflection characteristics related to its temperature is positioned in connection with the fluid communicating network and in contact with the fluids therein its temperature thus related to the temperature of the fluids;
- and
- an electronic part comprising an optical sensor and a light emitting device configured in optical communication with fluids within the fluid communication network through the transparent wall section;
- wherein the analysis device is adapted to estimate the temperature of the fluids in the fluid communicating network by the optical sensor detecting the light emitted light from the light emitting device being reflected by the temperature responsive element, and where the light emitting device and optical sensor additionally is used for estimating the transparency of the transparent wall section by the optical sensor measuring the light emitted by the emitting device being reflected within the transparent wall section.
