This National Optical model DC5-420TH stereo zoom microscope with digital camera features superb optics and precision mechanics, making it an excellent choice for lab, industrial, and university microscopy!  

The built-in 3.0 megapixel digital camera provides clear, high-resolution still and video images. The high-quality microscope delivers a zoom magnification range from 10x to 40x and every point in between.

This package includes the National Optical top-of-the-line model 420TH lab-quality stereo microscope with built-in 1/2" CMOS chip digital microscope camera, imaging software, and USB cable. The CMOS camera produces an incredible 3.0 megapixel image with 2048 x 1536 pixel resolution at up to 11 frames per second. Top-quality Motic Images 2.0 ML Plus software is included to view, capture, edit, record, count, zoom, file, and manage images.

The deluxe stereoscopic head on this digital microscope has paired inclined widefield 10x eyepieces and rotates 360° for viewing ease. Each ergonomic eyepiece has a diopter to correct for vision dissimilarity with your eyes and interpupillary distance adjustment to perfectly match the distance between your eyes. The objective lens fully adjusts from 1x to 4x (10x to 40x magnification) by rotating the zoom adjustment knob. The superb optical system provides an upright, un-reversed 3-dimensional image which remains in focus throughout the zoom range.

Other features include smooth and solid rack and pinion focusing, slip clutch, tension adjustment, large stable base, and extra rugged construction. The post-mount design provides ultimate flexibility in how the microscope is used, allowing the largest specimen size on of off stage. This stereo microscope is equipped with 15-watt halogen top lighting with directional control and rheostat for superb contrast control. Bottom lighting is 10-watt halogen and includes a built-in blue light filter. Light switches mounted on the base allow you to choose between using top or bottom lighting only or both at the same time.

This stereo zoom microscope comes with rubber eye shields, a dust cover, a USB cable, and instructions. National Optical Model DC5-420TH. Lifetime warranty for microscope, one-year camera warranty, 90-day software warranty.

Note: If you order additional 20x stereo eyepieces to double the magnification, they will only increase the magnification when you are actually looking into the microscope. The additional eyepieces will not increase the magnification on the built-in camera, so you would still only get 10-40X magnification when looking at the image on your computer screen.
