I have tried several times to get pictures of my beam from my 100mw 532nm but it always comes out very dim on my iPads camera any ideas of how I could get some better beam shots like angles side view?

first off its prob since its an ipad. iphone and ipads dont have great cameras and an android has a better camera IMO. not sure if an ipad has night mode but if so try that. i can easily get a good picture with my digital camera but with my android its a bit tougher, not impossible though. also if you can adjust shutter speed, then make it longer, allowing more time for the beam to be captured

532nm have a very thin beam (below is my 120mW 532nm)


my 400mW 532nm is easier to capture the beam with, will take a picture tonight

Get real camera, use low sensitivity + long exposure time. And smoke.

Exposure for 0.5 second and ISO at 800 for my DSLR.

You don't need smoke when you have air pollution and we get lots of that here

The best way to photograph a beam - no matter the camera - is to use some sort of fog or smoke in the air. This is tremendously effective when the laser power is lower and you can even get great beam shots from 5mW lasers when they have some particulate in the air to pass through... and considering you can get a decent fog machine for around $30US, it's a small investment compared to most lasers in this hobby. Well worth it imho!

Another thing to consider when photographing more powerful lasers is some sort of beam stop to minimize backsplash of light off where the "dot" is hitting.

Different cameras seem to have different sensor response to colored laser light and so if you have multiple cameras, you can try different ones to see which is "easiest" for you to accomplish your goal. I use an iPhone camera because it's handy, but my wife as a point-and-shoot camera I'm going to try next time as an alternative.

Seriously though... consider a fog machine. It'll make it much easier for you.

Be safe and have fun!
