Technical data
1
Since the working distance and lens choice can both have a slight effect on the amount of power from the laser head, it is difficult to
specify an exact power value.
“Laser Off” state is <2 V. “Laser On” state is 3 –
24V.
2
To use a PSU with voltage outside of this range, see the available accessories on our website.
We also offer a 12V power supply.

The High-Resolution Lens is a triplet (three-element) lens, f = 8 mm. This lens is recommended for applications requiring a more circular
beam spot, higher power density or medium to long working distance.
3
The High Efficiency Lens is an aspheric lens, f = 4 mm. This lens is recommended for applications requiring a higher power when it is
practical to use a shorter working distance.
4
Working distance is adjustable. The focused beam spot size depends on focal distance; shorter focal distance results in a smaller focused
beam spot size
