I manage a fuel business with multiple locations and I need to be able to
measure the fluid levels in my fuel stoarge tanks. We are presently using
measuring sticks. It is cumbersome and at times not very accurate.
I have seen the laser measuring tools in building supply stores and ...

I could use some input from any users of cooled CCD cameras regarding
types and prices. Is there a good, inexpensive camera out there with
decent resolution? I've visited a few "scientific" camera sites and
they, as is typical of scientific instruments, do not give you any idea

Can you please tell me what CO2 laser is so efficient and generate a
high power as compared to other gas laser ?

Just noticed on the Medialas website that they have announced a new and very
well priced scanner set.
Named TeraScan they are only Euro 555 for 2 scanners with mirrors, mounts,
driver & cables and will be available from Dec.

I have a lexel 88. For the first time I tried to power it up at my
house which has 240volts
I got it to fire instantly but it was really bright. I tried to adjust
the current control but it did not adjust. I cut it off and tried to

These days I received the lightwave lasers (110A).
I have a lightwave power supply and its model is 110A.
I tried to use it with RS-232 mode, but that is a little different compare
to 110M.

Hello group,
 I would really appreciate any advice, comments with this...
For my home built DPSS project, cleanliness issues have been causing me
concern and I've posted a question on it previously. I've decided to

Hy to all,
i need a certain help. I need a reliable but somwhat cheap laser module.
Im not sure from what producers to buy:
1. ExtremeLasers GXP 1000

I'll eventually buy one... probably something in the 30-100mW range... It
all depends on the price and how good the laser is...
But before I do, does anyone have one on here that they want to part with.
Maybe one of you has one but wants to upgrade to a higher power or

Hi ya'll
I live in a great apartment building in Olympia washington and I have a
project I need help with.
This building has 3' x 3' x 10' airshafts between each apartment that

I need some AR coated lenses for IR. Are there any suppliers that have them
in stock? I am not to picky on the fl as my requirements are flexible.
However I have little power and a good AR coating is essential.

I am hoping to use an SSY-1 pulsed YAG laser and a extra-cavity SHG to
make enough green to do pulsed holography.  There is a lot of good
information about this from Bill Jensen in the holography forum.

How much more damageing is a green 5mw laser pointer than a red 5mw
laser?

Help
I'm a Radio amateur beginning to look at optical communications, I see that
others are using large Fresnel lenses of about 300mm square  for
transmission and reception, I wonder if it's possible to make or buy some

Where would I get information about obtaining a license for running a
50-100mw laser?
For use in clubs and such. San Diego, California.
thanks in advance,
