Hi Race,
I opened the thing up and it says:
"Delta Tau 202-DSPGAT-000
9645TEC"
Also "PMAC V 1.148"
Which reminds me... I got two repair boards out at my supplier... will need to chase them.
I'm using it to control a diamond turning lathe.
Optical encoders control the lathe's position using laser interferometry.
The spindle's an air bearing spindle to reduce friction and expansion caused by heat. The whole lot's liquid cooled to further eliminate heat. And the lab it's in is temperature controlled... hehe I hate heat. Oh and humididty- I got that controlled since the refractive index of air changes with humidity and the lasers think they're somewhere other than where they should be.
Both axes and the spindle float on air and they are on an epoxy granite base. The base itself is floated on active air pads. The lab foundations are over thickness.
Software? I use the normal CAD CAM stuff and some special-to-type applications with custom post processors. I got fed up with limitations on the various lens software packages so I wrote my own. I called it BAGIT (Big Aspheric Generator Including Topography) it does stuff that other packages don't. It's not pretty but it certainly does the job
