(1)***********************************************************
Resonant scanners - 35.00$ each
1" X 3/4" X 2 1/2 "

- Great for the beginner at learning the basics of LASER
light shows or great addition to an existing system.

These are single axis scanners with F.S. aluminum mirror attached.
They say - American Time Products Bullova Watch Company. INC. NY
" " Type INT-L 45 HZ 750 - on one type
" " Type INT-L 45 HZ 2500 - on the other type.
Im assuming that one type is 2500 hz and the other is 750 hz.
At one time I had hooked one of these up to my sig generator XR2206
into LF357 op amp. - not lots of power. I had a HeNe bouncing
of of it and had pretty good deflection over a LARGE spread of the
audio frequency spectrum, with a few peaks at certain frequencies.
Mirror is mounted on a torsion bar in this type of scanner. Its
mode of operation requires that there is a continuously
alternating voltage applied to it, it could never "hold" a position
of the laser beam. It would be great for making abstract designs
and spirographs and can go pretty high up in freq. I was probably
doing this with the 2500 hz unit and maybe never tried it on the
other.
Both the 750 and 2500 hz look identical except for shape of mirror.
There are 2 sets of complimentary coils and I chose the beefiest
one
to drive it and the other set are probably for feedback.
I have no Idea what these were used in :-)

(2)***********************************************************
LASER checkout Scanner w/HeNe tube, HeNe supply and scanner.
Handheld Mini LASER Scanner (It doesnt look like a gun though)
Great for the beginning LASER experimenter for only 50.00$ !
- Enclosed LASER power supply (needs 12vdc external input)
- Technical sheets included.
- It contains a He/Ne tube, laser power supply and scanner
that is a small 4 wire stepper motor which is limited in its
rotation with a mirror attached to its shaft that deflects a single

line of LASER light on wall.
- From about 3 feet from a wall, the amount of deflection it
made was around 18" which appeared to scan at a sufficient
enough speed to produce no apparent flicker.
- 1 mW HeNe LASER tube (aprox?)
- LASER beam scanner is a limited rotation stepper motor.
- Enclosed scanner drive electronics.
- The manufacturer of it is Symbol Technologies Inc. It`s called
LASERSCAN tm and has a yellow class 2 Caution label with
1.0mW Max output rating. The model # is LS-6500-I00A, with
a date of 02/88.
- Its electrical connections are a coiled length of cable
terminatedwith a DB9 conector. This went to a box that was
aprox 1 1/2" tall X 5 X 5 inches. (this box is not available for
sale) It also has a chassis mounted connector similar to a
keyboard`s yet has 4 conductors. It went to an AC power pack that
I think had two +12vdc and one +5 vdc outputs.
(note-you do not get ac power pak or square box, the box is
available for 130.00$)
- I can not feel any type of "steps" when turning stepper motor`s
shaft by hand.
- The circuitry does not include any 7400 series semiconductors,
it has 555 timers and Operational amplifiers.

(angle of refraction through crystal is exagerated)

(Note that these specifications were derived from specs on an AOM
made by the same company with almost the same model# - two letters
were reversed? - the only difference that I can see is that you
power it with 12 volts, as far as most of the other specs,I cant
guarantee actuallity because I have no way of testing)

Argon LASER - forced air cooled/110vac, X-60 compatible.
Mfgr-NEC Model # NEC3030GLB rated 30 mW. TEM 00
Great for holography or LASER light shows. 488 nm output.
Price - 300.00$ For the:
Laser tube, its case, its chassis/case mounted umbillicle connector
(male AMP Conector) the optics - this is a functioning tried and
tested AIR COOLED Argon LASER . you dont have to assemble it, it is
fully assembled. You need a power supply though, and plans are
included to build one. Need help,you can always get a hold of me...

To use a laser like this (class 3B), you are supposed to get whats
called an FDA variance of CFR1040. ( a variance that allows usage
of LASER radiation in excess of maximun allowable levels)

Note: A commercially provided power supply can cost from
700 - 2800 dollars, depending on supply.
Cooling: Air cooled - needs excellent fan aroung 150 cfm.
Size: About the size of a shoe box.
Weight: Around 17 pounds.
Electrical: Has bananna jacks for monitoring LASER output
power and input drive current in amps.
Size 13" X 6" X 8 "
Protection: Has thermal cutout mounted on plasma tube
cooling fins.
YOU DO NOT GET: - Some other necesities to follow:

***** ***** Umbillical conector ***** *****
I can get a connector fully assembled now for 130.00$
The LASER head -to- Power supply conector is something to consider,
if you never plan on buying other air cooled argon laser heads, you
will find that they sometimes have a power lead coming off of them
around 2 feet long, long enough to connect to a power supply
nearby. On an Omnichrome 532 you will find that they have a
female connector hanging from them.............................
the higher powered heads have a new voltage to send up the cable.
(you could put this voltage there with this head but the voltage is

not needed.)

What I`m getting at is that you could build your power supply with
its connector coming out of it with a length of bundled cable,
and not be removable, - which complicates things later if you
decide to add additional wiring.

I can build/order cables for a mininum of 50$.
50$ example: chassis/freehanging length of a bundle of 20
smaller wires w/2 real heavy wires. it would not be covered with a

sleeve or outer protective,cosmetic covering. I could supply a
conector to hook to the head w/all required pins for 30.00$
***** ***** Power Transformer ***** *****
110vac in / 2.5vac 8A secondary, I can order one for 30$, you could

possibly find one like this in a microwave oven - if you do, be
careful w/its hv secondary-its dangerous.
***** ***** Power supply ***** *****
IS NOT INCLUDED - Plans are included with purchase, along with
technical suport in building it. It is a 110 vac Fan cooled design
(can draw up to 15 amps.) NO sample plans will be released without
purchase.
I have just decided that I would build a completely operating
enclosed power supply for 600$ if someone needed one or a
comercial unit for affordable price was not available.
The 600.$ would cover my work/materials/parts/labor/etc/etc/...
Note that my design uses no type of current or light feedback, it
is free running. Also I would add the module to make it compatible

with other X-60 series argons for additional 100$
***** ***** Other Misc.. ***** *****
Power Mosfets you need 450 PIV totalling at least 20 amps (parallel
configuration) An Ultra High Fast Silicon Recovery diode, 555 timer
dual +\- 12 v power supply, heavy duty choke and >4500uf @ 250 VDC.
------- Addition Information -------
I believe it was manufactured in 1988. It had an 0.E.M. purchase
price of 3000.00$. It had a bit of "black powdery (possibly toner)
dust in it so I think it was used in some type of printing/copying
fascimile. Some had Xerox stickers.. You do need a decent muffin
fan or one of these "Tarzan" fans 150 cfm as it will get real hot
otherwise. It does have thermal shutout if this happens.
With a prism/difraction grating in the beam you will see up to
around 7 different colored lines divided from the beam with
most of the power concentrated into the bluish/green one.
You do have to have it turned up pretty high to see the "extra"
colors. I dont think it was desiged for this higher mode of
operation though. This LASER does NOT have MULTIMODE mirrors.
Depending on the condition of the air, with lights dimmed, you
can definately see a blue colored beam going through the air.
With it turned up and some red thin plastic held in the beam
it will slowly burn a hole in it with laser cranked up. If held
with beam hitting bottom of plastic and the "filtered" light
going through the plastic bag material and onto the ceiling..
I saw great swirling patterns, it was neat to move plastic at just
the speed where the beam was about to pierce through.

The 2 mirrors are integral mirrors, and cannot be cleaned, they are
sealed to the ends of the plasma tube by flexible metal bellows,
allowing for mirror adjustment.
Mirror adjustment should not be required unless the unit has been
subjected to some type of jar, vibration, bump etc..

The Laser warning logo on it says :

"DANGER
LASER RADIATION
AVOID DIRECT EXPOSURE TO BEAM
ARGON ION LASER
400 mW MAX OUPUT
CLASS IIIb LASER PRODUCT"

Dont let the 400 mw excite you, the head is rated
at 30 mw (class 3b has a maximun level of 400 mw, I think)
end argon
