Main Question or Discussion Point

Hello everyone!

I have a system with 2 lasers and a single camera. I have two trigger inputs going to each laser, they have a delay of minimum 350ms. These triggers are split and need to be connected to the camera to open it whenever the lasers fire. So i thought of a Tee junction where i will have both the laser triggers coming in and a single output to the camera. Now the problem with this arrangement is that when laser 1 is triggered, the signal will go to the camera and also laser 2, due to the Tee, which will cause it to fire. How do i stop the signal from laser1 trigger from going to the laser 2 trigger and vice versa? I have attached an image of the arrangement.

Any help would be greatly appreciated.
Thank You
Thh

You need to keep the circuits separate. You "thought of a tee" now you are asking how to avoid the disadvantage of a tee. Don't use a tee.

Either that, or I am totally misunderstanding your question.

We need an easy method of isolation. Can you say what voltage is coming out of the pulse gen and what the camera requires to trigger?
