SOLD SOLD SOLD

LaserBee II 3.2W LPM

More info HERE for those who dont know what this is.

Practically brand new, 100% working. Only had it for a short while, and its only been out of the box to meter 3 lasers.

Comes with the original USB-SERIAL adapter, and software disk. Even ships in its original box.

I need funds for a non laser related project, plus I dont really use the LaserBee.

Asking $220 SHIPPED via Priority Mail.

I can only accept Google Checkout for payment, so you must have a CC/DC for payment.

Great deal on a great LPM!!

Re: FS: LaserBee II Laser Power Meter

Do you mean does it take time to warm up before using it when you turn it on? The answer is No. You can use it immediately.

If you mean does it take time to get a stable measurement, then Yes, all thermal meters do. This one only needs about 30 seconds to get a stable measurement, but that can vary depending on the power of the laser being metered. You can get a measurement in less time, but I would recommend at least 30 seconds for a more accurate reading. That is due to the laser stability though, not the meter.

Re: FS: LaserBee II Laser Power Meter

Ah, I think what I'm looking for is a LPM with and ophir head. Those give almost intimidate readings.

Thanks anyways and good luck with your sale!

Re: FS: LaserBee II Laser Power Meter

Ive had my eyes on one, and this is a good price. :beer:
Good Luck with your sale, and I hope I can find money soon in my budget to get one of my own...

The Ophir heads are more sensitive, however technically to get a accurate reading of your laser, due to laser stability, it would take the same amount of time with either. The instantaneous power of a laser is not its normal operating power. The only time a really fast head would be beneficial over one such as the LaserBee is if you were trying to meter a pulsed laser. For a continuous laser, you would allow some time for the laser to stabilize to nominal for an accurate reading, and that would basically take the same amount of time on any meter as its dependent on the laser, not the meter.

Im sure Jerry will chime in on this and provide more accurate info.

The LaserBee II is our top of the line LPM Product. It can read up
to 3.2Watts (3200mW).
Its response time to a stable reading is 10-15 seconds and has
a 90% response time of ~4-5 seconds.

Agreed.... the only reason I can see that one would need to know
the max reading as close as possible to the "ON" time of a CW
Laser like the 445nm LDs would be for bragging rights... ("Mine hit
XXXX mW Peak")...

Lasers are usually used for more than 10-15 seconds...

When one buys a Laser one would want to know what the run
time output was and what it would peak at with new batteries
for some sustained time.

The other thing to keep in mind since the OPHIR heads were
mentioned is that the OPHIR's radial thermopiles require one
to keep the Laser's beam perfectly centered on the OPHIR
Sensor's active area or Reading Errors WILL result.

By using a Wafer type Sensor (TEC) like Scientec and Gentec do..
the LaserBee products have eliminated that problem since you
can shine a Laser's beam anywhere on a Wafer Type Sensor's Active
Area surface and the readings will not change.

It is not that the OPHIR sensors are more accurate but that they
respond faster because of their Thermopile element architecture.

I guess it depends on what a buyer is looking for....
Response time speed VS Active area linearity

Re: FS: LaserBee II Laser Power Meter

Like new, so the thermophile is in perfect condition?
Some ppl may want to see a pic of it.

Isn't the 5W laserbee with an Ophir head your top of the line?

The Limited Edition 5W LaserBee is not going to be available
indefinitely. Once we run out of the OPHIR heads there may
be no more.

Hence the moniker "Limited Edition".
On the other hand the LaserBee II and all other LaserBee
products will always be available since we manufacture the
entire PCB electronics and the LaserBee Thermopile Heads..

Yes, it is in perfect condition. Why wouldnt it be? It would be kinda hard to damage it considering it sits recessed in the heatsink.

Re: FS: LaserBee II Laser Power Meter

You'd be surprised by the number of LaserBee Thermopile
Head sensors that have been abused by their owners...:eek:

A clear focused pic of your sensor's surface would calm
the curious and nay sayers...;)

Re: FS: LaserBee II Laser Power Meter

Ya, focus a 2W 445 and it will burn almost anything that is black,
your thermophile is no exception.

EDIT:
I now see why the 5w is called a limited edition,
So did you just sock up on the "new old stock" heads that were for sale a while ago?
Or do you buy them direct from ophir?

Re: FS: LaserBee II Laser Power Meter

We've bought some of our latest ones from OPHIR...
Our surplus ones are mostly gone...:cryyy:

Pics of thermopile added!!!

Sorry, but my knowledge of lasers far exceeds the level that would somehow make me want to focus my laser past infinity to meter it. To do so would not only accomplish nothing, it would just be silly. Im sorry if you had to learn this the hard way!!

Also, the "black" coating on the Laserbee thermopile isnt simply "black" like most objects. It is actually coated in lamp black, or soot, which is essentially pure carbon, which doesnt burn like almost anything else you would burn with a 2w focused laser.
