ir laser for photography project

Hello,
I am totally new in this world of laser and ir light. I am trying to photograph flying moths. I am working with lasers connected to a Camera Axe (Dreaming Robots Store). These laser beams are interrupted by flying moths and the camera axe detects this interruption with the help of lightsensors and so triggers flashlights. This is done in the darkness and with the camera shutter on bulb, which means very long shutter speeds.
Because of these long shutter speeds the sensor of the camera picks up the laser beam, especially in damp weather.

The manager of Dreaming Robots suggested to use IR or IR laser and I don't know where to start.

Googling IR lasers, I came to this forum and I hope that any of the members could advise me what to do. I am searching for an alternative for the laser that i have and can only use by very dry and clean air conditions. I hope that this way i will find something that:

.doesn't damage the moths
.neither my eyes
.could be used in conjunction with the Camera Axe

I would then also need a sensor that works with the Camera axe.

Any suggestion would be most appreciated.
Thanks,
Rob

Nobody with any suggestion??
Is this not the right place for advice about such project?

Most people here don't deal with IR lasers, at least not directly. You can probably just buy one on eBay and then have the beam hit a light sensor so that if the beam gets interrupted it triggers the flash. Try to get a low-power IR lasers, like around 5mW.

Welcome to the forum.

You may not be aware, it is pretty common for new members to pop on to the forum, and with little effort or searching, ask a question, and then disappear. Some ask that others do the bulk of the work in resolving a problem, without a contribution in return. We are a community with common interests. We enjoy discussion and education. If you're trying to learn, there are many, including myself, who want to help.

There is a ton of information buried in this website. The google search bar works really great, too. We invite you to seek, search, read and if you find something of interest that may contribute to a solution to your problem, then post more in this thread, ask, seek, and discuss.

The more we have to work to understand the setup your using, the more we have to ask, the more we have to type, the more we have to work and frankly, it's asking a great deal more than some have the time for.

I, for one, invite you to cultivate interest in your project. Show us pictures of your setup. Help us understand how the lasers are working, now, to trigger the camera. I'd rather you do that, then direct me to another site, where I must dig and read to find out what a Camera Axe is.

Show me pictures of moths. Show me some of those pictures with the unwanted laser beams in them. Spark my interest. I would honestly like to know more.

And if you're using a digital camera, you may already know (if you've searched this forum and read much about IR lasers) that you'll need an IR filter, because most digital cameras pick up on IR extremely well.

If you're not getting the responses you want, seek, search and read some more. Add to your post and ask more questions.

I've got other posts to read, so that is enough for now. I'll be looking for those pictures of moths!

On your camera axe specifications, does it say what wavelength (nm) of IR light it responds to best? e.g 808nm, 940nm etc.
