532nm 1W pointer is released now

[Frank]

Hi,guys

1W green 532nm handheld laser is ready now.

See photos.

Good looking unit. What are these selling for?

 

[joeyss]

Holy hell one watt of 532.

Thanks like

1400 lumens if you shine it on the ceiling. Which = a 100 watt incan.

 

[Cyparagon]

1400 lumens if you shine it on the ceiling

Is that number fresh from your ass?

A watt of 532nm light is 600 lumens. Source.

Hi,guys

What's the price for this 1w?

 

[ARG]

That laser is far too close to the power meter, probably nor a huge issue at 1W, but still...

 

[ChaosLord]

I wonder how much of that 1W is IR....

 

[Shakenawake]

Viasho is where optotronics gets it's units if I am not mistaken. wonder what the divergence is on these and if I could get my RPL converted. can we get more info please?

Looks like the price of the new 1W 532nm portable is $669 from conversation in Frank's visitor messages on Profile page.

Would be nice to know the specs including duty cycle and battery required.

Maybe I'm being naive, but why go 1W 532 over 1.5W 520 for half the price?

It's not like the beam from a 1W 532 will be the beautiful tight DPSS you think of when picturing a 532 of lower power.

I see individuals testing lasers that close the sensor all the time because it reads higher that way, for myself, I want to know the power at a 12 inches or more distance to give a higher accuracy reading, close up you always show more power. Also, would like to know if any of that power is IR? The IR is normally out of focus to the green, that's another reason, if it is present, it will read higher when closer, because all of the IR leaking through will hit the small sensor surface, if a foot or more away, likely unfocused and wider than that small one.

I'm interested in the divergence too, if 1.5 mRad or better that would be nice

For those asking questions, don't expect a response , Frank normally just logs in, "drops" his product , then logs out again, until next time.

Contact him at Vaisho.

It was from a chart i read somewhere okay.

I'm not making stuff up maybe i confused it with 560nm on the chart

I'm just doing my best to inform people and I didn't have the time to look up that chart again. I can't seem to find it was a check table I know it had 2 values for day and night vision in lumens for the lasers.



All I know is my 50mw 532 lights up my room better than a 15 lumen old school mag light does when i do the ceiling bounce test. hell even my green 400mwish laser had no problem lighting up my room about as bright as a mini-mag led which is like 200 lumens.

No and here's proof it's not from my ass. I'm talking about night vision aka Scotopic Vision vision


Brightness and Night/Day Sensitivity
http://hyperphysics.phy-astr.gsu.edu/hbase/vision/efficacy.html#c1

look at the chart yourself.

The scotopic efficacy curve is assigned a value of unity at 507 nm, and is represented by the symbol Vλ. To determine spectral Luminous Efficacy, the scotopic efficacy value, Vλ , must be multiplied by 1700 lumens per Watt. This value was adjusted from 1754 to allow both curves to obtain the same value of 683 lumens/W at 555 nm. So, a source we see with our dark adapted vision at 507 nm produces 1700 lumens for every Watt radiated, and any other wavelength produces a fraction of that value based on the efficacy curve.The scotopic efficacy curve is assigned a value of unity at 507 nm, and is represented by the symbol Vλ.

Scotopic vision sensitivity is generally meaningless in the context of this amount of light. The moment you were exposed to even 1/1000th of the amount of light this laser could produce your scotopic vision would cease. Those sensitivity ratings are more useful to gauge how sensitive your eyes are under extremely low-light conditions, where microwatts of 532nm might appear discernible to your eyes.

Photopic -- daylight -- vision is the standard. Mesoscopic vision -- between night and day -- would probably be the most applicable, but there aren't any standards on this, and usually it tends towards photopic and the ability of the eye to recover from short-duration light saturation.

Actually if you're pointing the beam at night it can become very important. since your away from the radiation source It like how I the ehought to i use red lasers to my advantage when astrophtographing. Mesoscopic vision probably plays one of the roles in why each person sees 405 so werid. I see the beam better than a 660nm but that's due to amtospheric scattering. Yet the variation is so great amoung people.
