AmScope SM10-V203 Barlow Lense/Auxiliary Lense with 1X Magnification and 48mm Mounting Diameter

1x Barlow Lens

Works as it should. Care should be taken as fine threads can be cross threaded if not aligned properly.

Excellent Lens Protector

This 1X Lens is a great way to protect the trinocular lenses on your boom scope.

This lens is the best! It lives up to my expectations.
