MEASURING MODULE FOR REMISSION PHOTOMETRIC ANALYSIS AND METHOD FOR THE PRODUCTION THEREOF

Jenoptik Polymer Systems ...

1. A measuring module for the remission photometric analysis of at least one specimen, the measuring module comprising:
a transmitting device with a transmitting channel emitting a measuring radiation to a location of the specimen;
a first focusing device focusing the measuring radiation onto the specimen;
a receiving device with a receiving channel receiving the radiation reflected by the specimen;
a second focusing device made of plastic focusing the measuring radiation reflected by the specimen onto the receiving device,
wherein the second focusing device also comprises a filter, wherein the filter is formed as a filter layer, wherein the filter
layer is formed as a multilayered system and has a thickness greater than 0.5 ?m and less than 4.5 ?m,

the filter removing a secondary radiation that is excited by the measuring radiation including autofluorescence of the specimen,
secondary maxima of the transmitting device, or ambient light.
