Variable Power Magnifying Glass

Use Fluid Separated Clear Membranes To Achieve Variable Lens Structure
  [vote for,

Some time ago, I saw that some bright spark had made some one-type-fits-all glasses. Each lens consisted of two pieces of clear plastic with an equally clear liquid in between. Using standard syringes, the amount of liquid could be varied. The plastic bulged to various, and customizable extents, allowing the glasses to be tuned to the indevidual needs.

Here, I'm stealing that principal for a magnifying glass. The large magnifying glass should be, like above, be two clear plastic films filled with a liquid. The liquid should be varied by having a resevoir in the handle. The handle should be a two-part squeezy pump type thing. The idea being that you can vary the magnification by squeezing the handle. Including a locking mechanism wouldn't be a bad idea either.

There's also scope for fixed, mounted version, with the magnification varied by a foot pedal. This would be useful for electronics, or the super tiny surgery that people occasionally let me do.

       This is utterly, preposterously remarkable.   

       Five minutes ago, I posted "Digital Magnifying Glass" - which was to be a conventional-looking magnifying glass with a camera on one face and a circular screen on the other. It had functions including "zoom" and "freeze frame".   

       As soon as I'd posted it, I Googled "Digital Magnifying Glass" and found many hits, so I deleted my idea.

       well, has to happen occasionally, or something, right?   

       As good as screens are, I think regular lenses will have a resolution advantage for a while. Also, my eyes at least can operate between different focal planes. A screen might screw that up.

       I very nearly just poked myself in the eye with a scalpel while moving loupes up. Might be about time to start wearing glasses I don't really need.

       I think screens will soon (or already do) match the eye for resolution. Remember, you'd be holding the screen at a comfortable distance, and things like the iPhone's retina display are already dense enough that I, at least, can't discern pixels or pixellation at normal viewing distances.   

       As for the depth issue, I'm not so sure. Depth perception through a standard magnifying lens is pretty screwed up already - if there's any depth to the image, it's common to close one eye. So bringing things onto a flat screen may be OK (though not the same as a binocular microscope, or a head-mounted magnifier with a lens for each eye).   

       Also, what are you surging?

       tail vein mouse, AAV9, heart-specifically messing about with mitochondrial Ca2+ channels/regulators.

       Cool. I was about to ask if adenoviral vectors can work on mitochondria, but I presume this a nuclear- encoded gene? (I've never done either mousework or viral stuff.)
MaxwellBuchanan, Jun 02 2015

       That's right, just overexpression. The other half of the project is a KO mouse.
bs0u0155, Jun 02 2015

       What's been KO'd?
MaxwellBuchanan, Jun 02 2015

       that's a little sensitive right now!
bs0u0155, Jun 02 2015

       Ah, fair point.   

       As far as I can tell, most knockouts just serve to prove that any gene, no matter how central it is to how many pathways, can be eliminated with no discernible phenotype. Howevertheless, I hope your mice turn out badly, so to speak.
