Line laser 100mW wide line width outdoor for safe public operation

Description

In this case the customer required a laser that can be used in a public place. The beam is static, at the distance 1m it is completely safe for human eye (Class I definition is 0.4mW per cornea). The beam line is 25mm thick at the distance 3m with total power 100mW, what makes the beam very well visible on the snow. The laser is mounted at a ski-lift entrance and projecting the green line onto the snow. The advantage of this solution is that the line is visible independent on new snow layer.
