My Rainbow -- Post Pic's of Yours

A short video of my 7 color / "white" rainbow!

Is a 5mw 635nm beam visible in the dark without smoke or fog?

Here are a few pics of a 635nm 5mW vs other reds in very little smoke:

Pic1: Beam shots 5mW 635nm

Thank you for the pictures, they are exactly what i was looking for.

Which beam in your picture is the 635nm ? and what mw is it?

It's next to the green beam. I have it set at 5mw on a DDL style driver. I also used smoke in the pic.

Sorry if you already saw these in a different thread, but I'm just so happy with the beam shots! And this thread is appropriate I believe...

These beam shots are from combining lasers in my version of the 7 color build first shown by rog8811.

These 'full length' beam shots are without smoke or fog. Just shining out into the night sky, and the camera set on auto exposure...

Already posted these in another thread, but they're applicable here as well. These are my greens and blues minus the multiline argon. 405, 473, 488, 532, and 543.

Here ya go. first is a $100 camera, second is a $30 camera. The cheaper one rendered colors better, but both incorrectly render the difference between 532 and 543 probably because the power of the DPSS pen is >10 times the power of the HeNe.

After a casual test performed in another thread of this Forum, I was curious to take a picture of three different beams refracted in the water contained in a glass square vessel.

So this is the picture:



The beams enter laterally from the right, and the lasers are 1 meter far and well below the vessel height, just to avoid any dangerous reflection; I had to be careful too about some horizontal reflection during the lasers setting (like the green one, clearly visible).....

Some data of the lasers:

IgorT LCC - 635nm - 312mW
CNI X150 - 532nm - 161mW
IgorT 8x BR 405nm - 413mW

Wow, that red is even wider than I thought it would be.

Wow I've never heard of a 543nm laser, I take it's gas?

Of course. HeNe IIRC

I don't have any pics of everything all together, but here's some of my collection:

First up: The Argon (self-contained partial rainbow)
JDS Uniphase 2214-40MLA
multi-line argon:
458nm, 476nm, 488nm, 497nm, 502nm, 515nm






Next: WL Spyder I Pro 200mW:




Finally, my 1W 532nm scanner and my ~500mW RGB scanner:

Green:





RGB: (A rainbow all it's own..)

My camera sucks. It rejects red which robs the colors of their richness. It is MUCH better to see firsthand.





I also have several assorted red, green and blu-ray pointers and lab-style lasers.

Allow me...

Pics taken in very dense fog last weekend.
Some beams apear multilined, however that was just my shakey hands (it was very cold, you know).

DIY red LCC 350mA

Bluray PHR 100mA, pen host, shooting in the sky.

Shooting at a house across the street.

MY rainbow...
Green used 50mW (aprox)


I tampered with some expo and ISO settings, to try get the most lifelike photo.
OFC that was impossible. Figures.
You can choose to have the surounding environment lifelike in the photo or the laser beam. Above was the environment, below are attempts to make the beam appear lifelike.


The laser itself, bluray above, was placed about 40 or 50 cm from camera, at aprox 90° angle pointing left.

Visibility was the same except that the beam was fuzzy, just like the dot. And OFC we all know the true color of 405nm light.


You will have to excuse my greenie, batteries were empty, and were put to charging after the photo was taken.
If I knew that there would be fog as dense as milk, I'd get all my batts fully charged.

Hope you enjoyed as much as I did.

Hulk 200mW + Spartan BP 40mW... Mode hopping sucks...

^pretty common in portable blue lasers, though.. nothing to be down about. Sweet pic!

would it be cheating to post scanner pics?

dont think ive posted them in this thread yet?

Holy crap Andy! Awesome registration on that LPF logo. U R da scanna masta. :worthy:

Cheers, CC
