Great investment for SMD electronic work

Reviewed in the United States on November 26, 2019

Verified Purchase

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.

Using this lens for hand soldering greatly increases clearance

Reviewed in the United States on December 27, 2017

Verified Purchase

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!

Reviewed in the United States on February 28, 2018

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.

Working distance to about 6-1/2"

Reviewed in the United States on February 26, 2020

Verified Purchase

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!
