Magnifier with handle. The body is made of plastic, and the lens is made of glass. The aspherical

surface of the lens provides high image quality when magnifying small

objects and images. The diameter of the lens is 60 mm, produces a threefold increase

Portable digital microscope USB 1000X 2.0 with a 2.0 MP sensor captures and transmits high-quality photos and videos with a resolution of up to 1920x1080.

The microscope connects to a PC and mobile devices with pre-installed software (Android/ Windows) via a USB interface. The digital microscope is designed for observation with adjustable magnification of up to 1000x of flat translucent and volumetric opaque objects.

The microscope uses 8 bright white LEDs with smooth

brightness control as a light source. The LEDs are evenly distributed around the lens

of the device to set up the correct even lighting for detailing

the sample being studied. The LEDs emit constant flicker-free light, due to

which the displayed image is comfortable for the eyes - free of distortion and stripes.

The microscope does not require an additional connection to the network during operation -

the device is powered via the USB interface. The sensor resolution is 2.0 MP. Connecting to a

PC or smartphone via USB. Photo and video shooting of an object with a high resolution

1920x1080. 8 bright white LEDs with smooth brightness control. Convenient

chrome tripod with stepless adjustment of the position of the su from a PC or

smartphone. The design of the complete table bracket allows you to

fix the microscope for examining an object at an angle. The microscope is easily

installed in the tripod and also easily removed from it to be held in your hand during observation. Features: Magnification up to 1000x, discrete digital

zoom 1-2x (in 0.2x increments).
