Visible at daylight

[Alaskan]

I want one too!

 

[Richie89]

The pointer you have is maybe 100mW - how much did you pay for it?


If you want a visible beam in daylight conditions as bright as you get at night then you'll need to spend a lot of money.

Hah yeah no kidding. I think even a 1 watt 520 beam would be difficult to see in daytime.

I remember Styropyro showing a 2w 532 having a beam slightly visible in daylight. But that laser was probably overspec too.

 

[Encap]

I said what this was earlier.

You are probably correct. From the nature and quality of the questions and lack of comprehension + they are about a < $10 laser 303 so it is easy to assume.

And this is how it looks like at night. The outdoor is pretty poor but indoor is astonishing

Depends on what you consider to be daylight.

Outside, on a sunny day, you're talking in the order of 10.000 lux, and even a 100 watt green beam might not be all that visible if the air is fairly clear. You can test prescense by sticking your hand in the beam and if it smells like bacon it's probably there.

Even indoor can be problematic, if you have a space with large windows and such indoor illumination can be 1000 lux or more on a sunny day, and you will not be able to see powerful laser beams either.

There is no way you could tell say 200 from 500 mW just by looking at how bright the beam is under daylight conditions, indoor or outdoor, since it's all relative, and the difference in ambient brightness between an slightly overcast and a fully clear day could be a factor of 100. On a very overcast day that could be a factor 1000 less compared to a sunny one easily.

Yea I kinda disappointed about it.

From the pictures you posted it is fine for what it is.

What do you expect from a bottom of the barrel, lowest end, mass produced, cheap Chinese laser that can be bought, retail, for about the same price as a good cup of coffee?

When you want to upgrade from a low cost toy quality laser to excellent quality laser with a very much more visable beam outdoors at night get one from JetLasers. See: 515nm - 532nm - JETLASERS.ORG

When you want to upgrade to a laser that isn't a low cost toy quality--excellent quality with a very much more visable beam outdoors at night get one from JetLasers. See: 515nm - 532nm - JETLASERS.ORG

You are right. Expecting something better than this with this price would be something really stupid but I disappointed about the beams are not visible at daylight and less visible than i expected at night and the ones with nice quality of beams are much more expensive than I expected. Also even they can't always meet your needs.

 

[Richie89]

To give you an idea of what some fog can do.

TOP TO BOTTOM:
105mW 520nm
310mW 473nm
<1mW 632.8nm HeNe

I just use my vape lol

Oh yeah! I remember that video. In his words "I just use it as a 1500 dollar lighter". Lol

Gonna try ( a 07 at ) 5A then 5.5 and go nuts with it.

Real curious to see how the 07 works at 5.5 amps? If it does, it's something I'd like to give it a go and have a grander. Best wishes, will be watching. :drool:

Edit, I'm serious thinking about trying to push a 044 at 6.0 amps just to try and see if she'll hold?

Check out Pmans thread http://laserpointerforums.com/f65/5w-07e-471nm-build-98461.html

I think I'll setup the 5A one and get a thread going soon.

 

[ArcticDude]

Not a green laser, but I thought to share this one..

Under the right conditions even 200mW red laser beam is visible on day time.. :yh:

Video Link >>

 

[lasersbee]

Have no problems seeing artic spyder during day lol

How about a picture of your Arctic Spyder with
a sheet of paper showing your LPF Username and
the date of your picture...

I'll also be interested in seeing this.
What power do you have Cyrus?
