I do like the fact that the photo diode, which needs to be compensated for wavelength, has a MPU that does that for you. It would be a good meter for checking low power gas lasers. A bit spendy for how much use we could get out of it, though.

Seems we like the same stuff, those are so cheap I bought ten of them a month ago, I figured nice starters for my little SSY-1 (I have several of those now).

I forget sometimes if I linked something or not.

You didn't, that's what I mean, we both thought they were interesting.

But, it says powers on, yet, I agree with the battery problem for the future. I believe they are calibrated to the battery, or is it once it dies, the calibration is lost in memory?

The battery is not dead since it powers on...
Then you have 30 days to return it.
I've had quite a few of these from used to Brand
New.
I've found them to be off by 0-20% testing between
them.

Do you know if this is the NDG700 or the NDG7475. If it is the latter, that is a great price for it. If it is the lower power version it is an okay price for it. By the made up spec sheet they show for it, I believe it is the lower power one. You save a little less than $20.00 over Jordan's prices.
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

It says 7475 and NEW however the 7475 I bought from this seller was in fact NEW with virgin pins, but it reads 775mw @ 1.8a through a green AR coated 3 element, so it looks very much like I got a 700, but I can't be 100%

DTR shows 1026mw from a ndg700 @ 1.8a through a G2 and 1187 from a 7475 @ 1.8a through a G2 ...So take away another 25% or so for my 3E lens and if I had a 7475 I should be getting 900mw not 775-780mw

From the unlenses starting power a G2 eats 5% and a 3E eats 30% so roughly I take away another 25%, should be about right.

Yeah, I remember Jordan saying if the current in the spec sheet is 1.8 amps instead of 1.7 amps, it is a 700. That was pretty much what I was going by, but you're right. If it were a true NDG7475 you should see more power out at 1.8 amps. It is still an okay price for a new diode. Would love to get the real thing for that price.

I won mine at auction for right at 100 dollars and I thought it could be a 700 even though it was advertised as a 7475, that's why I chose to use a 1.8a driver.

I also have a GBall 1w green that is putting out about the same power @ 1.8a and it was listed as refurbished, so far it has been running great de-canned with a 2 or 3e lens, I paid 40 something dollars for it, with driver, batteries and a flashlight host and self made heat sink I have a really cool 800mw green laser for under 125.00, granted I made a heat sink from aluminum bar stock myself and repurposed the flashlight springboard.

The next green GBall I get I want to be listed as NEW and I think I will leave the GBall intact and use a backwards G2 followed by a G7, I know DTR has some 2.0a SXD drivers for sale that should work really well.
