Plano-convex optical lens for experiments to produce a divergent laser beam, lens diameter: 12.5 mm
The plano-convex optical lens is placed, for the projection of standing ultrasonic waves, in the beam path between laser source and ultrasonic wave, to produce a divergent laser beam. The lens is fixed onto a rectangular glass holder which can be inserted into the corresponding slot in the laser support on the sample reservoir (order no. 20225). By simple insertion and removal of the lens holder, it is possible to change quickly between diffraction and projection experiment.
Dimensions of the glass holder: 25 mm × 75 mm
Lens diameter: 12.5 mm
Focal length of lens: 173 mm
