SKU: SM-3TPX-144-14M3-3PL
Availability: Unavailable
  • 3.5X-45X extended zoom magnification using high-quality Greenough stereoscopic objective lenses and a 0.5X Barlow lens.
  • A highly-versatile stereo microscope on a robust single-arm boom-stand which allows the microscope to be positioned at virtually any angle.
  • Dual diopters can be adjusted to maintain consistent focus throughout the magnification range, greatly improving productivity.
  • The stereo optics provide upright images with clear depth-of-field and a wide view for hands-on applications.
  • The simul-focal trinocular photo-port provides a dedicated mount for a camera, and can be used simultaneously with both eyepieces.
  • This microscope is ideal for laboratories, repair shops, and engravers.
  • Monitor and capture photos and videos with the included 14MP USB 3.0 camera. Professional microscopy software for Windows, Mac, and Linux provide tools for image processing, measuring, and more.
  • The 144-LED ring-light produces an encompassing field of bright light with reduced shadows for use with any application, and it uses a convenient control module to adjust brightness.

This microscope features a unique simul-focal optical system with an adjustable trinocular port to enable well-focused, clear images on your computer/video screen while simultaneously obtaining sharp, focused images through the eyepieces. Other trinocular microscopes may allow viewing through a photo-port at the cost of losing an eyepiece through switched-viewing. By sharing an optical pathway, this microscope's photo-port works concurrent with both eyepieces. Especially convenient for quality-control inspections, teaching-demonstrations, and many other industry-applications, your colleagues or students can simultaneously view clear images shown through the trinocular port while you work through the eyepieces. The 45-degree incline and high-eyepoint design ensures comfortable observation, including the use of eyeglass or goggles.

Mounted on a heavy-duty, single-arm boom-stand, this microscope has a wide range of movement along 3 axes, as well as rotation. This provides clearance and positioning that is ideal for soldering, inspection, and biological applications. A 144-LED ring-light provides a consistent light-source with bright, cool illumination. Mounted to the objective-housing, the ring-light will remain inline with the optics.

The 14MP USB3.0 digital camera captures still images and video, and allows you to view a live stream on your PC. With software available for Windows, Mac, and Linux, it's a multi-platform imaging solution. 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. For Mac and Linux, there is a lite version with limited processing features.

Simul-Focal optical system allows simultaneous observation through both the eyepieces and the trinocular port.

Have well-focused clear images on your computer or video screen and through the eyepieces at the same time.
