Key Components

  • EMZ-8TRU Trinocular Head with Top Light Port – 360° rotatable zoom head with simultaneous 3-port viewing and a fiber-optic top-light inlet aligned to the optical axis
  • MA502 Eyepieces – Pair of 10× Super Widefield eyepieces that deliver a broad, clear view.
  • CR-2 Articulated Arm Stand – adjustable spring-arm stand that allows flexible positioning over the sample.

Optical Performance

  • Zoom Range: 0.7× – 4.5× (zoom ratio ~6.5:1)
  • System Magnification: ~7× to 45× with 10× eyepieces 
  • Working Distance: 104 mm (4.1 in)
  • Parfocal zoom design keeps the image in focus while changing magnification
  • Greenough stereoscopic optics deliver high contrast, improved image flatness, and bright edge-to-edge viewing
  • Erect, unreversed 3D image output for natural depth perception and orientation

What It Does

People use the EMZ-8TRU + MA502 + CR-2 microscope system primarily for precision inspection, analysis, and hands-on work with small or detailed objects, especially when depth perception and flexibility are important. The stereo (3D) optics let users see objects with realistic depth, making it ideal for tasks like examining circuit boards, semiconductor components, scratches or cracks in materials, and biological samples that require careful manipulation. Its zoom range and high-contrast imaging help reveal fine details—such as surface defects, tiny structures, or transparent patterns—that are difficult to see with the naked eye or basic microscopes. The articulated arm stand is a big reason people choose this setup, because it allows the microscope to be moved freely over large, heavy, or fixed items instead of moving the sample itself, which is especially useful in manufacturing, repair work, and lab environments. Additionally, the trinocular design supports cameras for documentation or measurement, so it’s often used in quality control, research, education, and any workflow where you need to both observe and record detailed visual information.

Description

EMZ-8TRU: Trinocular Microscope Head + MA502: Eyepieces + CR-2: Arm Stand

EMZ-8TRU: Microscope Head
The EMZ-8TRU zoom body offers direct light to all three viewing ports simultaneously. The EMZ-8TRU has a special inlet for a single arm fiber optic light guide which allows illumination to be paralleled to the optic path which are designed for observing objects that are normally difficult to see under oblique incident-light illumination such as holes or cracks, scratches on metal surfaces, IC chips and liquid crystal patterns. The EMZ-8TRU is designed for high-contrast images and an excellent zoom range of 6.5:1 that is parfocalled all throughout the zoom range. The EMZ-8TRU includes Greenough optics for improved image flatness and contrast which results in brighter images at the periphery of the field of view. The EMZ-8TRU offers erect and unreversed stereoscopic images as well. Its modular versatility complements a wide variety of auxiliary lenses and stands that are available to allow users to customize their desired working distance to almost any application. Photomicrography made easy with over 300 available digital, analog and SLR camera adapters.
