Laser for tunneling
EN60825-1 Class 2
vidalaser
The electronic parts are designed in order to resist tension fluctuations that
might happen in tunnels and the optical part is protected by an easy to replace 5mm thick glass.
The internal part of the instrument is designed in order to avoid the inside
formation of vapour.
The FBL91 series lasers use the Halley86 base and have the same
level and instrument centre as the Halley86 series lasers.
This is the best set-up instruments to obtain the same calculation and work for all the Vidalaser instruments.
