  • Device for photometric analysis of a liquid sample and sample carrier therefor
    Patent number: 9188526
    Abstract: The invention relates to a device for the analysis of a liquid sample by way of light, comprising a transparent sample carrier, a movable upper mirror, which can be moved between a closed position, in which the mirror encloses a measurement space between itself and the sample carrier, and an open position, in which the sample carrier can be accessed so as to apply a sample, and a beam path, which guides incident measurement light between a light entrance into the measurement space and a light exit out of the measurement space from the sample carrier to the upper mirror reflecting the light. The beam path guides measurement light at an oblique angle of incidence through the sample carrier to the upper mirror.
