How To Keep A Loupe From Fogging


Recommended Posts

Here is the beginners question for today. When I use a loupe after about two to three minutes fog developes on the inside of the loupe such that I cannot see. I can take the loup off my eye and rub the fog away, but it returns in short order. It is so annoying that it makes using a loupe a chore. Is there a fix for this? Thanks in advance for your help and advise.

I tend to find it depends a lot of the eyeglass I'm using, my bergeon 3x eye glass never fogs for whatever reason, probably to do with the property of the materials used. my cheap 12x (two lenses) did until I drilled a hole in the body to allow the moisture to escape.

Weirdly enough it was my experience before then that my eyeglass would steam less quickly if my face and eye muscles were relaxed, but I don't know If I was just imagining that to be the case.

Bill I know exactly what you mean mate!

Nothing is more frustrating then a loupe fogging up when you're trying to concentrate on a difficult task.

 

This is why I don't wear a loupe any more.

If you'd ask me whats the best investment I've made in this trade, that's help me progress and given me a huge advantage, I'd tell you without a shadow of doubt: it's in optics.

 

The only optics I use is a pair of Carl Zeiss - Eye Mag Pros.  Yes they weren't cheap, but they have more than paid for themselves with the comfort and joy of being able to clearly see what I'm doing, and in stereo vision: giving me full depth perception; which an eye loupe will never do.

 

And guess what .... they NEVER fog up ... EVER!

 

Here's my write-up on them mate.

Just for the sake of the input, I follow the swimmers trick, being a diver myself, and spit in all glasses/optics in order to prevent fogging. It does work maybe because of my particular spit or because it is so, don't ask me why though. :)

 

Cheers,

Just revive this thread as a motorcyclist I use dish soap to stop my goggles from fogging up. It works I even use it on a mirror in my shower so I can shave....just take a drop of soap and apply a thin layer to the lense...it won’t affect clarity

    • As with every skill it watchmaking, it takes practice. Notice at the top of the document it says, "Practical work - 40 hours".  I can get the balance wheels 'close enough' to flat, but never seem to get them perfect. Same with gear wheels. Guess I need more practice.
    • Has it got a beat adjustment on the platform or is it a fixed hairspring? in short what you are looking at to get it just about in beat is to get the roller jewel sitting dead centre between the banking pins. So remove the platform and take of the pallet fork and escape wheel to give you clear line of site, sit the platform with the balance in place and with it level look between the banking pins and see if the roller jewel is sitting between them, if it is nice and central its there or there abouts in beat, if its not the the position of the pinned end of the hairspring needs to be adjusted to move the roller jewel into the correct position, thats why I asked if it has an adjustment on the platform or not, if it has its an easier job. 
    • I've managed to adjust it. I'm going to try and explain it as well as I can with my limited horology knowledge but I hope it helps someone in the future. There is a cam to the right of the front plate as shown in the picture. As the clock ticks along, the pin indicated in the gear comes around and slots into one of the silencer cam gaps, turning the cam. The pin completes a full rotation in 2 hours. To adjust the cam to start at the right time set the clock to just before 7. I did 6:45. Then I turned the silencer cam anticlockwise, which spins freely, until it pushed the silencer lever up and was placed just before the drop. Just before the 7AM indicated in the picture. All I then had to do was progress the hands to 7-7:15which made the pin slot into the silencer cam gap and turn the cam so the lever comes down again, unsilencing the clock. That was it. If anyone comes across this issue again I'd be happy to assist. Thanks again to everyone that helped. Hey Transporter! Thanks a lot for the reply. That was a really good explanation and I'm sure it would have made my troubleshooting a lot less painful haha. I'm sure someone will find it useful in the future. Thank you again for taking the time to try and help me out with this.
    • Now I'm completely confused, it would appear that the epilame  is oleophobic  as @Marc states: This oleophobic  behavior can be seen as beading of the droplet (as above) which stops the oil spreading which is supported by what we observe on treated/untreated cap stones (for example), but as @VWatchie states this should make the drops more mobile and is supported by the literature:   A review on control of droplet motion based on wettability modulation principles design strategies recent progress and applications.pdf   However the hole point is that we have less mobile oil so an oleophobic  would see to be the opposite of what we want. In fact this beading and high mobility are desirable properties in things like smart phone covers, see below.  I am fairly sure that epilame doesn't make the droplets more mobile, so maybe its a strange coating with dual properties that are both oleophobic (beading) and cohesive/adhesive resulting in low mobility?? This may explain the high price??  
    • The description there is exactly how it's done, and it's very well written!
