Beschreibung
Zusammenfassung:	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)αV=s1f·[αL-1n-1·(∂n∂λ·d⁢⁢λdT+∂n∂T)]+α2·(1-s1f).
