Carson MM-840 overview

  • 1Description

Carson's eFlex Digital Microscope is a handy and compact magnifying tool that is ideal for hobbies, crafts, or science projects. This compact, ergonomic, and versatile scope can be used both as a handheld device or be placed into a flexible arm on a stand for hands-free operation. The flexible arm can be secured with the suction cup, for positioning the scope and attaching anywhere on the base plate or other smooth surfaces. The base plate provides references for metric, standard, angular, and other units of measurement. At the core of the device is a 1.9MP CMOS imager, capable of capturing 1600 x 1200 images and 640 x 480 videos and delivering them to your computer via a USB cable. The magnification of the resulting images is dependent on the size of your monitor and scales at 3.6 - 14.3 times the size of your monitor in inches. For example, a 21" monitor will give you 75 - 300x magnification, while a 32" television screen will produce a 114 - 457x magnification. To deliver adequate brightness and clarity in many lighting conditions, the scope features a built-in LED illumination ring that's situated around the imaging sensor, under a transparent protective polymer bezel.

    Carson MM-840 reviews

    MM-840 eFlex Digital Microscope (White) is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from Usefull camera/microscope set at a good price with limits Basically works as intended which is to image very small items. In order to have a 3 field of view, the camera needs to be about 12 away. Fortunately, the focal adjustment still works at that distance. If you're trying to capture an image the size of a wrist watch face, you'll need to mount the camera about twice as high as the stand allows. The resolving power or primary lens quality appears to be better than the cost would indicate. A zoom lens option would be a great help.
