Look at the Diffrence between My 445nm lasers Arctic and My DIY In Color

Hello All,

OK, Here is a video that i was waiting to do again ever since i sold my first 445nm diode witch was a A130. I just got my Arctic in a couple of days ago and iam pretty sure they use the A130, as i cannot be 100% certain iam 99% sure:na: they are using the A130 Diodes because i guess coast and i can tell the difference in color.

Iam not going crazy or my eyes playing trick on me and i assure you that this is not a camera trick.

I distinctly remember my A130 diode being deep in blue next to my A140 back a few months ago. But its far enough away that it a slight memory until now.

Check out the difference. It is exactly how i membered it.:wave: That deep blue in color.

I can also assure you that it is not caused by heat or different outputs. I can change the A140 laser i have to put out lower then the arctic and it is still much more brighter in color then the Arctic witch is 99% sure again that they are using the A130 diodes.

A140 on the left and Arctic 99% sure A130 in the Middle To the Right is my 650nm Red laser


:thanks: For Looking. Ive got more videos coming in a few days

Re: Look at the Diffrence between My A140 and my Arctic i think A130!!!

I -really- think that's because the Arctic sits around 700mW and your a140 is doing around 1100mW. These diodes do shift up in wavelength with higher power, but they also will look a lighter blue...

I've seen the difference, too, but always attributed it to power alone.

Re: Look at the Diffrence between My A140 and my Arctic i think A130!!!

Yes i thought the same as well. My Arctic is 758mW and in this video my DIY is doing 1167mW. I can also drop the power of the DIY to around 300mW Give or take i cant remember what it does with an 18650 on my LPM, and the DIY A140 is still the same a brighter blue. Why.?

How come when i drop the A140 DIY lower in power to around ~300mW and the blue seem lighter/Brighter in "color" then the I think A130 in Arctic at 758mW.?

What ever it is I like it.

Heruursciences Had said something about the A130 and A140 a wail back about some difference and i cant remember what he said. If you read this Heruursciences please post.

Could i be lucky i got lower wavelength A130 twice and a brighter A140.? Thats why i see a big difference.:thinking:

Re: Look at the Diffrence between My A140 and my Arctic i think A130!!!

You probably ought to tune them both to the same power and divergence and then do comparisons, preferably with photographic evidence. It's easy to "see" things because you think you see them.

Re: Look at the Diffrence between My A140 and my Arctic i think A130!!!

LED_Museum once did spectrometer analysis on Arctics.
They sat at 440 nm at High mode and 439 nm on Low mode.

So what this guy is seeing is actual 10 nm wavelenght difference.

If you remember correctly, spectrometer analysis of CNI's lasers is 449 nm, which are most likely to use diodes closer to A140 ones, if not actual A140 projector diodes.

Re: Look at the Diffrence between My A140 and my Arctic i think A130!!!

The difference was only 439.48nm (low) to 441.40nm (high) on the Arctic, which is about a 2nm difference, and both are in the flat region of the blue response curve for human color vision. That may be noticeable, but I don't think a fair judgment can be made without equal conditions.

Uhh you misunderstood me, I was talking about how A130 diodes, obviously used in Arctic, and average at 440nm, are fairly differentfrom A140 diodes which are more around 449 nm.

Not the difference between low and high mode, but between different diodes.

Re: Look at the Diffrence between My A140 and my Arctic i think A130!!!

I still have a laser device I built with a diode from an A130. That device is running at 440mW. I compared it to another laser device that used a diode from an A140 running at 700mW and I did notice that the device with the diode from the A130 did appear darker and more toward the violet range but I had attributed that to the power difference.

I have managed to get the Arctic through the damn customs (which is funny for the amount of hasstle, because it's perfectly legal here),
And I have a labby setup with A140 that'll go into my laser scanner/projector, but for now, I can compare it with variable power from labby unit.

Will wait until weekend for that though.

Its going to be great to see when the Lasers Match in Power what will be the results. I am unable to do this.

Thanks cant wait to see.

Edit: I also sent a PM to Heruursciences to see if he can post what he said back then.

Re: Look at the Diffrence between My A140 and my Arctic i think A130!!!

The brighter it is, the more light it appears to be. A 5mW green will look deeper than a 1W green even though they are the same wavelength.

Do you have a power meter?

Yes i do. I also want to mention that iam talking about the actual color of blue in the A140 being brighter the the deeper color of the 130 blue being brighter now the beam.

I have tested the A140 at 300mW next to my 758mW Arctic and it still looks a brighter blue.

Edit: Iam charging an 18650 right now to see How many mW my DIY A140 Laser puts out. In my A140 DIY Build i use 2 x 3.0v RCR123A batteries. If i use the 18650 witch i use once in a wail the output drops to around 300mW i cant remember what the actual output was so once this 18650 charges up i will check the mW of the A140 laser.
