EMZ-13TRH + MA522 + PBL, Stereo Zoom Trinocular Stand Configuration System, Magnification (10X – 70X), W.D. 90mm (3.54″)

Key Components

  • EMZ-13TRH Trinocular Head with High Eye Point– High‑performance zoom stereo microscope body with a 7:1 zoom ratio for a wide range of magnification.
  • MA522 Eyepieces – High eye point pair of 10× Super Widefield eyepieces that deliver a broad, clear view.
  • PBL Stand – A LED illuminated pole‑type stand with built‑in transmitted and incident LED lighting and integrated focusing holder, plus reversible stage plates and stage clips for sample support.

Optical Performance

  • Zoom range: 1×–7× (continuous, 7:1 ratio)
  • Total magnification: ~10×–70× (with 10× eyepieces)
  • Eyepieces: MA522 10× high-eyepoint (long eye relief, glasses-friendly)
  • Working distance: 90 mm (room for tools under lens)
  • Optical design: Greenough stereo (true depth perception)
  • Field of view: ~23 mm → 3.2 mm (wide → detailed)
  • Image behavior: Parfocal (stays focused), parcentered (stays centered)

What It Does

The EMZ-13TRH stereo microscope head is designed to provide a clear, magnified, three-dimensional view of objects for detailed inspection and hands-on work, allowing users to smoothly zoom from low to high magnification while maintaining focus and image quality, observe fine surface details with depth perception, and even capture photos or video through its trinocular port, all while offering enough working distance to manipulate tools or components directly under the lens—making it ideal for precision tasks like electronics inspection, assembly, medical device work, and quality control.

Description

EMZ-13TRH: Trinocular Microscope Head + MA522: Eyepieces + PBL: Stand

 

EMZ-13TRH: Microscope Head
The EMZ-13TRH 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-13TRH trinocular zoom body is used for photography and video applications and offers an extended zoom ratio of 7:1, the highest in its series. Its modular design enables the user to select a magnification from 3x – 420x. Because it has a large zoom range, the user can expect superb optical performance and maneuverability. The paired objectives are parfocalled and parcentered which guarantee observation of high resolution images throughout a wide magnification range. The EMZ-13TRH series offer working distances from 34mm – 252mm. The EMZ-13TRH employs Greenough optics for improved image flatness and contrast. As a result, images are brighter and more distinct even at the periphery of the field of view. The EMZ-13TRH is suitable for precision-oriented semi-conductor, medical device and routine inspection. In addition to its compact design and versatility, a wide variety of auxiliary lenses and stands are available to allow the user to customize their desired working distance to adapt to almost any work/lab application.

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)

PBL: Pole Stand 
The PBL Stand is Meiji Techno America’s newest 100V LED stand with a built in transmitted and incident LED illumination which may be operated independently or simultaneously. The PBL stand is equipped with a F focusing holder that has an 84.5mm round diameter opening, mounted on a cast aluminum alloy base stable stand. This stand includes a 94.5mm diameter reversible black and white stage plate (MA568), a 94.5mm clear glass stage plate (MA569) and two stainless steel stage clips (MA593). The PBL Stand is mostly used with the zoom EMZ Series but can also be used for our turret (EMT Series) and fixed (EMF Series) stereo bodies. It is a great complement to our stereo microscopes due to the focus block’s ability to easily raise vertically if needed for special applications. A 5” extension pillar for the threaded vertical post is also available if needed to accommodate taller specimens (MA551).
