The handheld digital microscope AM4113ZT Dino-Lite Pro is a product extended from handheld digital microscope AM4113T by adding rotatable polarizer filter. This model uses the H11 housing which is the second generation housing for the Dino-Lite that incorporates: improved magnification dial movement for smooth and easy adjustment and focusing with the Dino-Lite, 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. Simply by rotating the polarizer filter, the handheld digital microscope AM4113ZT could amazingly decrease the reflection glare to almost any extent, and could thus help the user see through the surface of fully or partially transparent materials, such as jewelry, skin, glass, and plastic, or see clearly the high reflectivity materials, such as metal or soldering. The handheld digital microscope AM4113ZT could be very useful in some application including PCB, printing, machining, textile, jewelry, or skin care etc.
