TE incoming  :D
Made an offer on a bit of TE on ebay and it was accepted. Item was completly mis-described as seller (of lots of surplus TE) obviouslt didn't know what it is.
Been looking for one of these for years but they normally sell for 10 - 20 times what I paid for this one. That is too much for an item I don't actually need (yes, yes this is the TEA thread but funds and space are not unlimited).
So who knows what it is? The electricity goes in the bit sticking out the side.

A bit of a wild guess... It looks like a precision position sensor or more likely precision actuator, possibly fits on a larger optical or microwave device ?

Must be a warp drive considering they are hot on this forum right now.

Measurement gauge of some sorts. Adjustment wheel to the left?

Name includes AC and something seems to go through.

So a plasma nozzle then.

You might be waiting a while for a response, he hasn't posted on this forum since August 2022.

I See, thanks :)
Anybody else with LF-3200 perhaps?

I'd probably use practically what ever with decent ergonomics, if parts are available longer than tail lights are visible.

Back in the day there were two, Weller and Pace, both are still present.
(former iron and latter sucker was my setup)
Strong brands.

SMD probably changed things, but strong brand it must be if it's going to grab some space.
Xytronic seems to be regular stuff here, iron like [inventor] and sucker like Pace.

Xytronic is also reasonably priced.
Maybe next generation of pro-buyers is needed for new brands.

BTW,
late '80s when new MIL-STD came out and pulled back, Magnastat was also ordered not acceptable.
Technical or political, who knows.
But quite a bit of new stuff was rolling out, so technical side has a probability.

getting close but most TE measures somthing. The wheel/knob is connected to a scale marked in seconds...

A parallax meter.

Hmm, its method of use is a bit hazy.

Oh, how pleasingly ambiguous :)
There are lies, damned lies, statistics - and ADC/DAC specs.

Ding, ding, ding we have a winner! Shame there is no prize.  >:D
It is indeed a autocollimator. A Hilger & Watts, probably a TA50 but I've not received it yet to be sure. It can measure angles with a resolution of 0.1 second of arc (2.778^10-5 degrees) using a mirror as a target.
It doesn't have the stand normally used but it was probably used directly in a custom fixture. I paid £70 including shipping. Further reports when it arrives...

Engine boring, how accurate a crankshaft direction must be?

More used to check other measuring devices, straightness of machine tools etc.

Just tried to find a perspective, arc second is not very usual for outsiders.

One rule for long exposure of star photography is 0.1 arcsec of movement in at a time of one round/sidereal day.
(nice fellas those Babylonians)

E,
that first version, was it a bit slow.
So actually 12.96M steps/round and one round/23h56min04.0905s.
And a step being 1mm when radius is a bit over 2km.

They had one of those in the cal lab at work, used with the largest of the granite blocks, for exactly what you mention. I remember fixing the cable between the power unit & the lamp, can't remember which version they had, but the power unit was this one. https://rochesteravionicarchives.co.uk/organisations/hilger-watts
No idea if it's survived the stupidity & wasting of measuring equipment at work.

Funnily enough I saved some metrology kit from work a while ago. Did a swap for a bit of kit the needed. The was a stack of kit but I only took a few pieces that they had two off AND a H&W polygon mirror. Should have taken more, two weeks later I was picking slip gauges out of the bottom of a scrap bin. Anything bigger they had smashed up before putting it in the scrap  :--

Good to hear you managed to save something at least, no chance for me to do the same, unless I want a P45 & police record, requests to buy waste are auto-denied.  |O
Thankfully I wasn't there when they trashed everything, they cleared it sometime when I was off work following the heart malfunction. Last time they put the skips outside, to make sure the weather destroys everything over several months.

As I went through an electrical apprenticeship, I never got to use any of the equipment in the mechanical calibration area, they might still have something for checking pressure gauges & torque wrenches, no idea if the shadowgraph & precision length measuring machine are still there, & all the other bits I can't remember anymore. Most calibration is now outsourced to some crappy external company, where things sometimes don't return.
