A device (1) for analysis of absorption measurement on small amounts, for example on a drop or droplet of a liquid medium (2) using light (3) is provided, with an upper planar location (4) for the application or dropping of the medium (2), a light entry (5) in the housing (6) arranged beneath the location surface or receiving position (4) and a first device (7) in the light beam behind the light entry (5) for deflection of the light upwards to the receiving position (4) where a detachably mounted reflector (8) is also located. The device (7) for deflecting the light beam is designed such that the direction of the optical axis of the deflected light beam is oriented upwards toward the middle (M) of the device (1) and the inclined position of the optical axis of the light beam with regard to the device mid-point (M) is arranged to be directed at the position of the reflector (8) through which the longitudinal median (M) between the light entry (5) and the light exit from the device (1) extends. The height of the assembly of the device (1) relative to such a device in which the light is first deflected about a right angle and only then after a further direction change is directed at the receiving position (4) or the sample, is correspondingly lower.
