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.
  • P Pole Stand — A compact vertical support with a reversible black/white stage plate and clips, saving benchtop space.
  • MA551 Extension — Extension pillar that lengthens the stand’s vertical column to provide extra space.

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 + P: Stand + MA551: Extension

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)

P: Pole Stand 
The P stand in Meiji Techno America’s basic pole stand with “F” focusing holder mounted on a plain base. It accepts our EMZ, EMT and EMF stereo microscope 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 P 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.

MA551: Extension Pillar
This P stand also has a MA551 attachment which is a 4″ extension aluminum pillar in which gives the whole stand a height of 348mm. The P stand’s 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.

Modular design enables the user to engineer their own custom solution for virtually any application, selecting components from the widest range bodies, stands, eyepieces, supplementary lenses, illuminators, camera adapters, and accessory components available in the microscope industry today.

Superb Optics:
Multi-coated optical components, free form chromatic and spherical aberration, provide crystal-clear, high resolution images. The Greenough optical design provides superior erect, unreversed, stereoscopic images, rich in contrast, brightness and correct in their original color. Excellent depth of field and a flat image rendition are also characteristic of the EMZ Series product line.

Rugged Dependability:
All-metal aluminum alloy microscope bodies and components with chemical resistant finishes guarantee stability and rugged dependability for a lifetime of day-in and day-out use. Superior craftsmanship, quality components and materials result in long-lasting, high-performance products.

Ergonomic Design:
All EMZ Series zoom stereo microscope bodies feature a compact lightweight design. Every stereo body features adjustment diopter tubes and interpupillary distance adjustment. Observation tubes are inclined at 45°, 60° or 90° for convenient fatigue free viewing depending on the application, A range of fixed of tilting focus blocks are available to mount the microscope body onto existing O.E.M. equipment. A choice of Zoom, Turret or Fixed magnification bodies with various working distances, optional auxiliary objectives and eyepieces, multiple adjustable stands, versatile illumination systems, and auxiliary components allow the end user to design a system to fulfill their specific requirements.
