Two very nice Tek 2215A oscilloscopes, 60 Mhz, dual trace, dual delaying time base, Excellent condition, removed from university basic lab class where they were used 1 day a semester and one day in the summer then stored in a climate controlled instrument storage room. Would prefer to know if you want to buy them before the trip, to avoid hauling them 750 miles for nothing. Have XY mode for hooking to your show controller. These also have a "Z" input for modulation and blanking. 95$ each at Selem, or can be shipped. These need to go, to pay for Selem this year. These are the last Tek "Glass CRT" scopes, and very high quality, made pre Carli, so not the modern Tek junk.
Two sets of NEOS 64070-120-1AS with ISOMET or Mitsu 80 Mhz AOMs. Programmable frequency AOM or AOBD drivers, 1.25 watts of power, rotary switches on front to program from 70 to 120 Mhz in roughly 7 khz steps, as well as a optional digital input on the back for frequency as well. Neos tells me they can go outside that range a bit. These units have a frequency synthesizer in the them. 1AS means 1 volt analog signal = full drive, and these have a front panel test switch. So basically a really high quality tabletop or rack AO device driver and a AOM cell. I'll be glad to mod them for 0-5V as needed, as you just add a resistor. AOs have TeO2 crystals, so can do blue, green, red. The 70-120 Mhz and Digital input means you can scan as well as modulate with these. A careful person might get them to other neat "things" with a multiline argon, like picking out a single line or Q switching some small YAG. 125$ EACH SET, will negotiate a bit. Will be glad to bring counter/RF power meter/laser and show they work. These things are a WORLD CLASS widget!
ISOMET 100 Series AOBD driver with NEOS Acousto-optic beam deflector crystal. Make your own laser TV projector. Has a built in sweep generator that ramps the frequency, from 20-135 Mhz as needed, ie you can set upper and lower frequencies, or use a external sweep, does something like 5 watts of RF, lots of knobs on the front and a NEOS OEM BEAM DEFLECTOR. If you want scan times measured in microseconds, this is your beast.
pics on request. Also drives Small Qswitches and regular AOs. I bought these two parts to build a NTSC laser video projector and never finished the project. Asking 200$ for the set. 19" rack 2U high case on the driver. I used to use it to test AOMs, because it will drive nearly anything.
The magic disk:
Laserman532 color wheel. Made when he was very rich and still somewhat sane. You need to see this thing to understand it, you spin it, its a medium sized glass disk, and it has a bunch of circular dichros deposited in rings across its surface, so as you slide it across a RGB or Whitelight beam, and spin it on a motor shaft, it generates color changes. Its not like the wheels from video projectors, this thing has smooth GRADIENTS in between the colors. Makes one hell of a killer abstract colorizer, even if you just use it with a spinning motor spirograph or something. I have not tried it at 405 or 445, but it was designed for 457 to 676 nanometers. In factory box, coated by OCLI just before they got bought by JDSU Read really expensive custom coated disk, from "Back in the day". 200$. I'll throw in a piece of ball bearing linear slide, but you'll need your own motor. New in box. Makes killer abstracts even more killer. This was to do planetarium shows in wicked color without a pcaom. Another project I bought parts for and never finished.

VERY NICE SCOPES and AOM stuff
