Key Components

  • EMZ-8TRH Trinocular Head with High Eyepoint – Trinocular stereo zoom microscope head with 0.7×–4.5× parfocal zoom and high‑eyepoint eyepieces, offering clear 3D visualization and simultaneous camera capability for precise inspection and analysis.
  • MA522 Eyepieces – High-quality eyepieces for sharp, comfortable binocular viewing.
  • PC Stand – A precision pole stand that holds the microscope and lets you focus smoothly with coarse + fine adjustments.

Optical Performance

  • Zoom range: 0.7×–4.5× continuous zoom (6.5:1 ratio) for smooth magnification changes without refocusing
  • Standard magnification: ~7×–45× when used with required 10× high eyepoint eyepieces
  • Working distance: 104 mm, providing plenty of space for tools and manipulation under the lens
  • Optical design: Greenough stereo optics deliver high contrast, flat field, and true 3D depth perception with bright edge performance
  • Parfocal zoom: Focus remains stable throughout the zoom range

What It Does

Stereo zoom trinocular microscopes with high‑eyepoint eyepieces are designed for applications requiring highly detailed, three-dimensional observation of objects while maintaining a comfortable working distance and the ability to manipulate items under the lens. They are widely used in electronics inspection and repair, allowing precise examination of circuit boards, solder joints, and small components, as well as in precision assembly and manufacturing, where accurate alignment and placement of tiny parts are critical. These microscopes are also ideal for quality control, metrology, and defect analysis, enabling operators to detect subtle surface features and irregularities. The trinocular design allows simultaneous camera attachment for documentation or instructional purposes without interrupting the live view, while the high-eyepoint eyepieces provide comfortable viewing for users with glasses and reduce eye strain during extended use. Additional applications include medical device inspection, educational demonstrations, jewelry making, watchmaking, and other hands-on tasks where both fine visual detail and space to work under the objective are essential.

Description

EMZ-8TRH: Trinocular Microscope Head + MA522: Eyepieces + PC: Stand

EMZ-8TRH: Microscope Head
The EMZ-8TRH is a new and improved high eyepoint model with an eye relief of 20.9mm designed for microscopists and for people who wear glasses. It is specially designed to give the user more clearance between their eyes and the microscope. The high eyepoint models also use a newly designed eyepiece with a wider designed lens to compliment the high eyepoint models (MA522 10X, MA818 15X, MA819 20X). Optional rubber eye guards (MA906) are also available. The EMZ-8TRH Trinocular High Eyepoint with 0.7x-4.5x zoom ratio offers direct light to all three viewing ports simultaneously. The EMZ-8TRH is designed for high-contrast images and has an excellent zoom range of 6.5:1 that is parfocalled all throughout the zoom range. It has Greenough optics for improved image flatness and contrast which results in brighter images at the periphery of the field of view. The EMZ-8TRH offers erect unreversed stereoscopic images providing high resolution observation in precision-oriented semi-conductor, medical device and routine inspection.

MA522: Eyepieces 
MA522 Super Widefield Eyepiece is included, high eye point 10X (paired) (With 25mm reticle mount) (Fits EMZ-5H, EMZ-5TRH, EMZ-8TRH, EMZ-10H models only)

PC: Pole Stand 
Is included PC stand in Meiji Techno America’s basic precision pole stand with “FC” focusing holder with coaxial coarse and fine focus block mounted on a plain base. This stand is designed for applications where precise fine focus adjustment is required. It accepts our EMZ, EMT and EMF stereomicroscope bodies. Supplied with a 94.5mm diameter reversible black and white stage plate with a locking pin and two stainless steel stage clips and a 20mm diameter vertical pole. The PC stands compact design allows users to maximize their work area, so that operation in limited space becomes possible. Since there is no built-in illumination, it allows the end-user to select from a variety of incident light options from an LED ring light to a dual arm fiber optic system.
