I had a stereo microscope for working on electronic circuit boards, but when focused, the optics were so close to the board, it was difficult to solder or probe. This lens dramatically increases the working distance, allowing ample room to access the items under the microscope. An added benefit is that the inexpensive lens protects the microscope optics from possible scratches, fumes, residues, etc. I’d rather replace the lens than the microscope.

Extends the focal length to allow room to work.

does exactly what it was supposed to do, reducing the magnification range of my AMScope stereo zoom microscope. However, I was not quite prepared for the doubling of the working distance. That changed the usage ergonomics a lot. It was worth it, but some optical trick to keep working distance similar while reducing magnification would be nice. Maybe better option would be lower magnification eyepieces.

This is what you need if you're doing SMD soldering under the microscope. It increased the working distance between the bottom of the microscope and focal plane to about 165mm or so. Even though it reduces the magnification by half, you still have plenty of magnification for soldering and inspection needs. I think this barlow lens increases the working distance enough that you wouldn't need the 0.x35x lens to increase it further. I didn't note any obvious degradation in the image quality; the edges of the fields still appear to be in focus and it didn't seem to add any chromatic aberration. At least on my Amscope microscope, the LED illuminator ring is affixed above the original microscope objective lens, so it's possible to unscrew the barlow lens without much of a fuss if you find that you need more magnification. For my application, I've not needed to do this.

4 stars because this is an excellent addition to your Amscope microscope and SHOULD be highly considered. - The best addition that I could have made!! This gave me alot of space between the working area (electronics in my case) and the scope without loosing out on much of the original magnification. 1 star left off because I firmly believe that Amscope could have provided this much cheaper for Amscope owners.

A perfect addition to my AmScope binocular scope for use in PCB assembly and repair. I can get enough magnification to see any detail, and still be able to zoom out and get a wide enough field of view for hand soldering. The image quality seems just as clear as with no Barlow lens installed. The only quibble I have is, on my scope, if the item you are focusing on has some depth or is raised off the work surface at all, in order to get clear focus when zoomed all the way out, I have to raise the Microsoft boom a little beyond it's maximum height. But that's not really the fault of this lens, just an FYI. The 0.7X lens might be a little better option because of that, but at the difference in price, this lens is fine.

If you do watch repair with a sterro microscope this the lens to use, makes over all view larger and cuts down magification.

Installing the Barlow lens was kinda tedious .. the threads are very fine .. I pulled the head out of the mount and finally got it threaded in. The tolerances are very tight, which is fine .. just take extra care. The working distance is barely adequate, with both the rack and boom all the way up. I did loose maybe a quarter inch by adding a UV protection lens, to keep smoke and splatter out of the scope itself. On Amazon .. Fotodiox Metal Step Up Ring, Anodized Black Metal 48mm-49mm, 48-49 mm, and, Tiffen 49mm UV Protection Filter. For $15 bucks .. cheap insurance to keep "stuff" out of the scope lenses proper. I'll probably make a "riser" to raise the vertical column bar a couple of inches. Cheers!
