EMZ-5TR + MA502 + F + BAS-2, Stereo Zoom Trinocular Stand Configuration System, Magnification (7X – 45X), W.D. 93mm (3.66″)

Key Components

  • EMZ-5TR Trinocular Head – The main optical unit that provides zoom magnification (0.7×–4.5×) and produces a clear 3D image using Greenough stereo optics and allows simultaneous viewing through eyepieces and a camera/monitor.
  • MA502 Eyepieces – Pair of 10× Super Widefield eyepieces that deliver a broad, clear view.
  • F Focus Block – A rack‑and‑pinion focus holder that lets you adjust focus smoothly and precisely with coarse focus control.
  • BAS-2 Stand – Sturdy ergonomic boom support stand with a horizontal arm and vertical pillar, providing flexible positioning of the microscope head over the work area.

Optical Performance

  • Zoom Range: 0.7× – 4.5× (zoom ratio ~6.5:1)
  • System Magnification: ~7× to 45× with 10× eyepieces 
  • Working Distance: 93 mm (3.66 in) — plenty of space between the objective and the subject for manipulation or tools.
  • Sharp, high-contrast stereo images
  • Excellent depth of field for 3D specimen viewing

What It Does

A stereo zoom trinocular microscope is used for viewing and analyzing relatively large, three-dimensional specimens at low to medium magnification, making it ideal for tasks that require depth perception and manipulation. Commonly used in fields like electronics repair, biology, and quality control, it allows users to examine surfaces, textures, and structures such as circuit boards, insects, plants, or small mechanical parts. The “zoom” feature provides a continuous range of magnification without changing lenses, while the “trinocular” design includes a third port for attaching a camera, enabling users to capture images or video for documentation, research, or teaching.

Description

EMZ-5TR: Trinocular Microscope Head + MA502: Eyepieces + F: Focus Block + BAS-2: Stand

 

EMZ-5TR: Microscope Head
The EMZ-5TR trinocular zoom body is used for photography and video applications. When the beamsplitter is engaged, 100% of the light from the left optical path is directed to the phototube. The image can still be viewed through the right eye tube. The EMZ-5TR employs Greenough optics for improved image flatness and contrast. The EMZ-5TR offers high resolution erect unreversed stereoscopic image. 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. Photomicrography made easy with over 300 available digital, analog and SLR camera adapters.

MA502: Eyepieces 
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.

F: Focus Block 
The F holder is a focusing holder with a rack and pinion mount that allows smooth, precise focusing over 55mm of travel. Coarse focus mechanism incorporates a slip clutch and tension adjustment. Fits 20mm diameter, 71mm long mounting post. The 84.2mm diameter opening accepts all EM Series stereo bodies.

BAS-2: Stand 
The BAS-2 Heavy Duty Boom Stand is Meiji Techno America’s most popular Ergonomic boom stand with pillar, crossarm and a 20mm drop down mounting post accepts industry standard focus blocks with a 20mm mounting hole. The BAS-2 is equipped with a 635mm (25”) vertical pole and a 457.2mm (18”) horizontal pole. The BAS-2 offers minimal space requirement and greatest possible amount stability for EM stereo system up to 30 lbs. There is no loss of stability even at its furthest travel. The BAS-2 can swing out of the way easily, clearing the workstation for other tasks. The horizontal arm can be moved freely and smoothly left to right or can be securely locked into position with our spring-loaded 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 BAS-2 Heavy Duty Boom stand provides a comfortable amount of space for large Solar panels to large semiconductor and electrical components. The BAS-2 is supported by a 80.00 lbs. base. 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.

Modular Flexibility:
EMZ Series zoom stereo microscopes are most the rugged microscopes from Japan and tailored to fit the needs of each and every customer. 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.
