Dino-Lite USB Digital Microscope AM4113ZT - 1.3MP, 10x - 50x, 220x Optical Magnification, Measurement, Polarized Light

The Dino-Lite Premier Handheld Digital Microscope is a product extended from handheld digital microscope by adding rotatable polarizer filter.

Simply by rotating the polarizer filter, the handheld digital microscope could amazingly decrease the reflection glare to almost any extent.
This lets the user see through the surface of fully or partially transparent materials, such as jewelry, skin, glass, and plastic.
Similarly, users can see clearly the high reflectivity materials, such as metal or soldering samples.

A scroll lock feature for assuring desired set magnification/focus, and a cable strain relief (SR) that holds the Dino-Lite and its USB Cable together for greater resistance from pulls and twists.
