Aperture on QTX lasers?

Aperture on QTX lasers – Think I would fail these.

 

A DJ mate bought a used QTX 3D Spiro laser from a reputable disco equipment supplier. Although it comes as PAT tested he asked me to have a look as he has had problems before with other suppliers. The Spiro has no lens to cover access to the electrics inside. A quick email to the supplier confirmed that it is made that way as a lens would distort the laser effect. The supplier also added that he thought it was “all low voltage at that end in any case”. I am not comfortable with this.
