The invention relates to an athermalized device for generating laser radiation that is focused in a focal point, comprising a lens and a plastic housing and a passive adjustment system for adjusting the object distance S1. The passive adjustment device has an effective coefficient of thermal expansion (I) 

Athermal laser optics made of plastics

A measuring module for remission photometric analysis of one or a plurality of specimens is provided with the following features: a transmitter with a transmission channel for transmitting a measuring radiation to location of the specimen; a first focusing device for focusing the measuring radiation on the specimen; a receiver with a receiving channel to receive the radiation reflected by the specimen; a second focusing device made of plastic for focusing the measuring radiation reflected by the specimen onto the receiver, whereby the second focusing device further comprises a filter which is designed to filter a fluorescence radiation from the specimen excited by the measuring radiation.
