AmScope SM05 Barlow Lense/Auxiliary Lense with 0.5X Magnification and 48mm Mounting Diameter

Excellent product

All good!

Definitely buy a Barlow lens

So, I bought the "AmScope 7X-45X Magnification Simul-Focal Trinocular Zoom Stereo Microscope Head", and the focal plane was really obnoxiously close to the objective, making the microscope hard to use. Once I got this Barlow lens it was perfect, and is now the best microscope I've ever had by a wide margin. Definitely 100% buy the Barlow lens (at least for that head, but I assume AmScope's other heads are similar).

0. 5 X Barlow Lens

Excellent quality and easy to install. Gives excellent field of view and plenty of working room under the scope
