This is a trinocular 3.5X-90X zoom stereo boom microscope with 5MP heavy-duty high resolution digital camera. It comes with a trinocular head, 30mm super widefield high-eyepoint eyepieces, 3D double-arm heavy-duty boom stand, and 144-LED ring light with control box. This microscope offers crystal clear images, super widefield of view, very large magnification zoom range (26:1), and large working distance (8", 200mm). Its high-eyepoint optical design ensures an easy and comfortable observation, including eyeglass wearers.

The 5MP digital camera captures still images and video, and allows you to view a live stream on your PC. The included Windows software offers image-development and measurement tools, as well as advanced compositing features such as image-stitching and extended-depth-of-focus. Independent preview and capture resolutions allow you to view high-speed video while capturing high-definition images.

The 3D double-arm boom stand allows you to turn the microscope head around three different axis (x, y, and z), allowing you to point the microscope head to ANY direction you wish. The intensity-adjustable LED ring light provides bright, even and cool light illumination. This microscopy system is an ideal instrument for gemologists, engravers, collectors and anyone in semiconductor and/or electronic industry. It is also a right microscope for biological laboratory applications that require low heat release.
