The number of people suffering from diabetes mellitus is rising dramatically. It is important for the patient’s quality of life that they regularly check their blood-sugar levels, sometimes several times a day. With the constant improvements in the measuring methods, the devices require less and less blood for these measurements. This project involved a customer that develops and produces these types of devices in large quantities. Before the final construction of the means of production, the company had Zühlke assess the design of the mechanics, optics and electronics as regards design and assembly. One part of these checks involved an integrated optical photometer.
Zühlke conducted two tests on the integrated optical photometer. The geometry of the entire ray path was modelled in the raytracing tool “Opticad” and the parameters were set so that the individual members could be varied easily in accordance with the mechanical and optical tolerances.
