Abstract
The transmission measuring cell determines the optical absorption of a sample fluid. A light passage opening introduces light in the container (12). A reflector unit (26) aligns the light in such a manner, relative to the container, that a large part of the light passes through the container, without multiple reflections at a wall of the container. The substrate (10) is made of silicon. The container has an elongated shape. The container is closed by a cover (20). The reflector unit is a wall, inclined relative to the longitudinal direction of the container. A beam transformation of fed light is effected by a lens (6), whilst a further lens effects the reverse operation. ADVANTAGE - With small consumption of sample fluid or reagent, facilitates high determination accuracy.
