EMZ-5TRD + MA502 + FS + S-4400, Stereo Zoom Trinocular Stand Configuration System, Magnification (7X – 45X), W.D. 93mm (3.66″)

Key Components

  • EMZ-5TRD Trinocular Head – Trinocular stereo zoom body with Greenough optics for crisp 3D viewing and a trinocular port for attaching a camera.
  • MA502 Eyepieces – Pair of 10× Super Widefield eyepieces that deliver a broad, clear view.
  • FS Focus Holder – A rack‑and‑pinion focus block that lets you smoothly bring samples into sharp focus.
  • S-4400 Boom Stand An ergonomic articulated boom stand with vertical and horizontal adjustment, making it easy to position the microscope over larger specimens and clear the workspace when not in use.

Optical Performance

  • Zoom Range: 7× to 45× total magnification
  • Working Distance: 93 mm (3.66 in)
  • True stereo (3D) depth perception
  • Optics Quality: Bright, sharp, high-resolution optics (Greenough— known for bright, flat, high‑contrast images)
  • Zoom Ratio and Click-Stops: The head has a 6.5:1 zoom ratio with detent click-stops so changing magnification is smooth and repeatable.

What It Does

The Meiji EMZ-5TRD + MA502 + FS + S-4400 Stand Configuration System is a professional-grade stereo microscope setup engineered for detailed inspection and precision work in industrial, research, and laboratory environments. At its core is the EMZ-5TRD trinocular zoom head, which offers a 6.5:1 zoom ratio with detent click-stops that delivers bright, high-contrast images throughout a 7×–45× magnification range, thanks to its Greenough optical design that enhances image flatness and clarity. This makes the system ideal for tasks such as semiconductor inspection, medical device evaluation, and quality control work that demand clear, accurate visualization.

Paired with MA502 Super Widefield 10× eyepieces for a broad, comfortable field of view, this configuration also includes the FS focus block that provides smooth, precise focusing with adjustable tension. The S-4400 ergonomic boom stand offers extensive horizontal and vertical positioning flexibility, allowing easy access to larger and irregular specimens while maximizing workspace efficiency. Designed to accept a range of optional illuminators and accessories, this modular microscope system adapts to various lighting and inspection needs, making it a versatile tool for professional microscopy applications.

Description

EMZ-5TRD: Trinocular Microscope Head + MA502: Eyepieces + FS: Focus Block + S-4400: Boom Stand

EMZ-5TRD: Microscope Head
The EMZ-5TRD body offers detent click-stops and delivers sharp, high-contrast images and an excellent zoom range of 6.5:1 that provides exceptionally high-resolution images all throughout the zoom range. The EMZ-5TRD 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. With the large zoom range, the EMZ-5TRD offers high resolution observation in 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 application.

MA502: Eyepieces 
Is Included is the MA502 Super Widefield Eyepiece 10X (pair) with 25mm reticle mount Field No. 23.0, Eye Relief 16.0, Focal Length 25.0.

FS: Focus Block 
Tilting focus holder with integral, adjustable illuminator port. Rack and pinion mount allows smooth, precise focusing over 55mm of travel. Coarse focus mechanism incorporates a slip clutch and tension adjustment.

S-4400: Boom Stand 
Focusing The S-4400 Boom Stand is Meiji Techno America’s most popular Ergonomic boom stand with a Bonder Mount Socket at the end of the horizontal arm accepts the industry standard 5/8″diameter microscope mounting dowel. The bonder mount socket accepts FS and FSC holders which can be inclined at 180 ° and rotated 360°, 16mm diameter mounting pin. (Must be ordered separately) Equipped with a pillar, crossarm and 610mm (24.00”) vertical pole and a 530mm (20.86”) horizontal pole. The S-4400 offers minimal space requirement and greatest possible amount of work room. The S-4400 can swing out of the way easily, clearing the workstation for other tasks. The horizontal arm can be moved freely left to right or can be securely locked into position with our T handle knobs. The vertical column is used to compensate for taller specimen heights to accommodate the working distances of different microscope bodies. Anti-rotation is stabilized by a locking pin on the vertical post. The S-4400 Boom stand provides a comfortable amount of space for preparing mice, insects and other model organisms or semiconductor and electrical components. The S-4400 is equipped by a 35 lbs. base. The S-4400 boom stand is designed for the zoom (EMZ Series), turret (EMT Series) and fixed (EMF Series) stereo bodies. This boom stand is affordable; low cost with high quality safety features makes this boom stand unmatched value in its class. This stand has ample height and long reach to work on an inspect small to large parts under the microscope. Ergonomic flexibility, chemical resistant paint finish and corrosion resistant stainless-steel columns make this boom stand an excellent choice in labs and production facilities.
