The AM413ZT is a product extended from AM413T by adding rotatable polarizer filter. Simply by rotating the polarizer filter, the AM413ZT 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 jewerly, skin, glass, and plastic, or see clearly the high reflectivity materials, such as metal or soldering. The AM413ZT could be very userful in some application including PCB, printing, machining, textile, jewerly, or skin care etc.. ■Medical Care Digital Microscope ■10x~50x-200x ■Buit-in 8 white LEDs ■1.3M pixels.
