Dye laser is here. Anyone have an idea how to take the covers off this damn thing?

[Laser Ben]

Dye laser has been trimmed a bit, all of the useless medical crap has been pulled, all I need to run it now is 120V for the pump and 12V for the fan. I will pull the shutters and photodiodes when I get it lasing.

Jon's reply is spot on with regard to the ledex rotary solenoids. Some of them will pull in at 12 V, but the ones I have want between 13 and 15 to actuate. And yeah, you can design a little "idler" circuit that drops the voltage down once they pull in to save on heat. They'll hold just fine at 9 volts. Just pulse them with 15 volts to snap them in, and then drop to 9 volts to hold. I think George has a schematic for the circuit he used to use.

Truthfully I don't use any ledex solendoids anymore. I found that I didn't like the noise they made. (Too loud.)

Ben, I don't have time to go into details why, right now, but leave a shutter between the pump laser and the dye...
Also be careful, that gear pump is capable of well in excess of 100 psi..
Just trust that 90% of the time I usually know what I'm doing... And I've seen what happens when dye fountains like spurting blood...

OH, and BEN, DUE TO THE DISASTER , We cant talk about molarity or where to get dye. I'll help you off thread..

I got the chiller, LBO temp controller, SSRs, and 24V PSU today.

Eeek, I would hate to see that happen! The unit has 2 pressure switches, one for 10PSI and one for 15PSI, I think it is meant to stay between those pressures.

being a cell system it is low pressure...100 to 150 psi are reserved for dye jet systems.

you appear to have R110 in that system if my dye color correction eyes are working properly

in case you havent heard...prodjallen knows everything about those systems if you find yourself in a pickle.

Yeah! I heard I can make more then 5W of blue by only replacing the dye!

I have about 10 grams of 7-diethylamino-4-methylcoumarin if you want to trade for something. I know it makes blue but can't remember pump and output wavelengths.

silly boy...if it makes blue it is a UV pump...its that old pump... florescence... thing going on
