Inexpensive LED loupe

I've owned too many cheap coin loupes. They don't work well; for $4 or $5 you get distortion and a very small field of view.  It's easy enough to find $40-$50 versions than don't have those problems, but it really ticks me off when I lose one of those.

I found a compromise at Amazon.  This 10x, 21mm triplet loupe gets almost 5 stars from reviewers but is under $20.00. Click here for Amazon Link. 






This loupe gives you good quality and I am deliberately not adding "for the price". It's good quality, period. Read the Amazon reviews; you usually don't see that degree of satisfaction until you reach twice the price.

The LED's switch on with an easy to operate slide switch. That's likely to last much longer than a button. 

With LED's ON

I had never owned an LED loupe before this. Now that I have, I wouldn't consider anything else. Of course you don't have to switch on the lights if you have good illumination from elsewhere, but when you don't have good lighting, this is a life saver (well, a money saver or a money finder, depending on the circumstance).  It takes a watch style battery and it's easy to change when that becomes necessary,

The lights do wash out colors, but they eliminate shadows and let you see when you would otherwise have been cursing.

I recommend this highly. Shipment was slow, but worth the wait.

AGPtek® USB 800X Digital Microscope

Strictly speaking, few of us really need a microscope to examine our coins. A 7x loupe is enough magnification for almost anything you need to see.  That said, a microscope can certainly make examining details easier and it especially makes taking digital pictures easier.





A really good digital microscope can cost hundreds of dollars. I cheaped out and bought a 
$39 model at Amazon.




The reason I picked that one is that it was inexpensive and it has Mac software.  I have Windows XP and Windows 8 installed in Parallels Desktop on my Mac, but I'd rather not have to run those if I don't have to.

Setup was easy enough: plug it into a USB port, install the software and I was able to take this:



That's 20X magnification.  I had to get the picture using Skitch (a Mac screen capture tool) because neither the red photo button on the camera nor the software photo button worked. That's fine; I'd rather use Skitch anyway.

You adjust magnification using a rather stiff thumbwheel. Supposedly you can get anywhere from 20x to 800x, but Amazon reviewers say it really is only 100x maximum.

I could not get focus anywhere but at the bottom or the top of that range. This is what I got at the high end.  Whether that is 100x or 800x or something in between, it is more than enough for my needs.



The microscope includes LED lights that turn on by a switch on the unit.  The instructions warn you not to turn on the lights unless their software is already running - they don't explain what might happen if you are careless, but they do mention "electronic damage".




I'm happy with this purchase, though I'd prefer something easier to focus.
