Liquid lenses with lasers

So if this works with a laser it may be possible to make a auto ranging Pew Pew to light unsuspecting coworkers socks on fire from distances.
laser tape measure + arduino + 405 w/liquid lens = "remember that time your socks burst into flames?"

Bad idea.

I was thinking it'd be more useful using these lenses with tracking software and camera and making some sort of bug zapper :D

Bobhaha: I am also interested to know where you are getting these lenses from.

Awesome. I know they have liquid filled optical stabilization lenses but I never knew they had something like this.
I'm glad bobhaha is already going to test them so I can try to resist taking on another project. Really interested in this. :pop:
If anyone finds a decent source for Liquid Lens Drivers, please share.
If you can find it the Fujitsu Siemens Webcam 130AF also lists a liquid lens. Digitus DA-70817 is out of stock. :(

Ha, I was thinking exactly that...

bobhaha, where are you getting your 9 lenses from? I assume you arn't going to buy 9 of those webcams and pull them out. I can't find anywhere that will sell them in singles or cheaply, then again, I havent looked in a while.

That is exactly what I'm doing... The only way to get these lens individually is to buy a development kit from the company who makes them. I have already inquired about the price... any one have a spare $10,000? :undecided:
 
What are you going to do with the cameras after removing the lenses?
I bet you can substitute a fixed lens. Don't know if components could burn out while it continuously tries to drive the missing lens.
 
Wouldn't the electrical signal input into the lens cause the water to vibrate to a point where the beam dot is visibly vibrating, would be a cool effect but not very practical.

Plus wouldn't IR light heat the water up?

So your the one who bought all of them....:whistle:

Perhaps you may wish to part with one? The seller doesn't have any more.

Looking forward to what you make of them though, they look like a lot of fun if you can get them working correctly.
 
If you are purchasing them from the same place as me... ask the seller to contact his supplier in germany for some more.. I'm still waiting for mine to ship.

@Misanthrop It doesn't vibrate... why would this be used in a camera if it had vibration issues?? :thinking:

But doesn't the electrical signal vibrate the water to a certain frequency to create the different focus?

Bobhaha - what lenses did you get your quote on?

I'm looking at trying to source some Varioptic Arctic 416 lenses. They seem to be the smallest and could possibly fit into a handheld device.

I went in search!
And found a more deep explanation for the Liquid lens here

Scott Huang - Liquid Lens Project

I looked for the webcams in other places, these things are a pain to get!
I do have a friend who works for Foxconn and will see if she can get her hands on some lenses as Foxconn is likely to have liquid lenses in their facility. If so I will let you guys know.
 
I'm not sure this is really good technology to have in a high powered laser. Or a portable. For one, under high powers, you have to worry about your lens 'boiling off'. And also, what happens if you accidentally drop your laser and your lens dislodges and splashes on the diode? heh
 
I keep checking on this out of curiosity because it seems like a cool experiment. Like qume said though, it seems like a bad idea for high powers, and portable applications. Still looking forward to see how these function with a laser.
