Blue Laser Installation

[Kvist]

Hi there.

I want to project a blue laser around two corners using mirrors, to lead people from one place to another. Can you recommend a laser that can be turned on for at least an hour, and some mirros + stands to go with this?

I've added some picture which might be helpful for you.

Best regards Jakob

Green is more visible. How much
ambient light is there? A small labbie
would work but how far?

It's an outdoor installation, so there will be ambient light present. However, I'm also concerned about the application of a blue 447nm laser, since the beam will expand quite a bit , given the distance of approx. 70m. But a green will be more visible, but also more affordable, and will it the beam expand less than the 447nm? Cheers

Outdoor? I hope you mean at night time because this wont work well in daylight and not at all in direct sunlight. You will need a powerful green lab model and it wont be cheap.
