Description

A lens with short focal distance (f=-5 mm) is the first component of the beam expander system which actually is made up of this module and the module (4745213) . For the directional adjustment with regard to the optical axis this lens is mounted in a holder which can be adjusted in the XY-direction as well as in two orthogonal angles θ and φ. The combination of both lenses yields a magnification of 4 resulting in a beam diameter from initially 1.5 mm to 6 mm.
