What is it? Set 361

[Rob H.]

I need some help with the second one this week:

[RogerN]

2077 looks what I have seen called an optics bench. Sometimes used with lasers or other light sources for optical design and experimentation. I have seen similar items in Edmund Scientifics optical catalog. RogerN

It does, yes. But with all the wind-up carousels and rotating reflectors and the big condensor lens, I think it might be a lighting special effects projector -- although I've never seen one that looked so "lab"-like.

2080. A folding surface gauge. 2081. A hand pumped polishing flywheel possibly for lapidary work, but more likely for scientific work. R

[Rob H.]

Partial credit for being correct about it being a projector although it's not a typical one, it could be described in two words, the second of which is projector. Also correct for saying that it's lab-like.

[Rob H.]

Nope, part of this one is missing, it can still function without the missing piece but it would be more easily recognized if it were there.

Yes, it's for scientific work.

2081. A hand pumped vacuum chamber, missing the bell jar? Art

It's a microscope projector, using a carbon arc lamp.

Good answer!

Robert Milikan did the oil drop experiment to determine the charge on the electron

is credited with its discovery

[Martin Eastburn]

looks like a precision 'Oil spot' lab machine. The machine might be able to do radial testing of optical crystals as well.

Mold for blown glass?

[Rob H.]

It isn't any type of mold.

No, like I said before, it's a carbon arc lamp illuminated microscope projector.

Hey! I finally got one right! Bring 'em ON!

[DoN. Nichols]

And quite old too -- based on several features of its construction.

and clicking on the "Troubleshoot" link does not do any good -- perhaps because I am not browsing from a windows box. :-)

Enjoy, DoN.

Bad link. It is missing the 'x' at the end.
