    • Great investment for SMD electronic work
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. ... show more

    • This is a great value for the money
I'm using this on a 50-year-old AO StereoStar stereoscopic microscope. My scope has a 47mm thread, so I had to 3d print a 47mm to 48mm adapter. The lens gives me a much larger distance from what I'm working on, a larger field of view, and the picture quality is superb. This is a great value for the money. ... show more

    • Using this lens for hand soldering greatly increases clearance
This item is ideal for hand soldering using an AmScope SM system. Without this extender, there is very limited clearance between the objective and the object. I often found I had to tilt the head to get enough clearance for the soldering iron under the LED illumination ring. After installing this Barlow lens, I had to lift up the arm on the scope traveler mechanism almost to the top of it's mast to get good focus. The result is that I can sit up straight, and there is plenty of room between the circuit board and the light ring - no trouble at all! ... show more

    • Perfect magnification for PCB assembly and repair
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. ... show more
