What is the beam diameter?
The beam diameter varies: it is about 6 mm for the VIBRANT and 2.5 mm for the Opolette. The beam is diverging and the divergence angle depends on the model and the operation wavelength. Some of this divergence can be corrected with a single lens. The beam can be projected with an imaging lens to the target. By selecting the proper lens you can control its beam diameter on your target.
