AmScope SM05 0.5X Barlow Lens For SM Series Stereo Microscopes (48mm)

I find that when using the Hakko Omnivise, and seriously, everyone should have an Omnivise, the subject is either too far away with the default magnification, or it's too close with the usual 0.5X Barlow lens. This 0.7x lens results in about 5" of working height between the lens and the subject, which for me, is perfect -- plenty of room to work, and the eyepieces are at a good height for long-term comfort and ergonomics.

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.

Great solution for those moments where you need the scope, but want a wider field at a lower magnification - jewelry and watch repair are perfect examples!

The 0.3x needs sufficient height for it to focus, at least 14” working area. If you have a SM-4 that means this won’t work which is what many other reviewers are complaining about. I recommend a 0.5x lens for those folks. However, I have a sm-6 and was able to raise the entire scope and now have about 14-15” working area. My next upgrade is to get a 4k camera instead of 1080p for the extra clarity/pixels.

Good price for a good lens.

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.

Works fine but not sure how much I will use it. Good to have.

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.

una estrella no merece porque no funciona al final perdi 57€, no me devuelvan me dinero, no vuelo a comprar jamás de esta empresa

the item arrived as described

As expected, no problems, no hassles.
