EMZ-13TRD + MA502 + F + S-4200, Stereo Zoom Trinocular Stand Configuration System, Magnification (1.0X – 7.0X), W.D. 90mm (3.54″)

Key Components

  • EMZ-13TRD Trinocular Head with Detent– High‑performance zoom stereo microscope body with a 7:1 zoom ratio for a wide range of magnification.
  • 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.
  • S-4200 Stand – An adjustable stand with vertical column and horizontal arm for positioning the microscope over samples.

Optical Performance

  • Zoom Range: about 10× – 70× total magnification (with 10× eyepieces)
  • Working Distance: 90 mm (3.54 in)
  • Optics Quality: Uses Greenough stereo optics for bright images, good contrast, and depth perception.
  • Sharp, high-contrast stereo images
  • Excellent depth of field for 3D specimen viewing
  • Dual bilateral zoom knobs with detent click-stops make magnification repeatable, accurate, and easier to select.

What It Does

A stereo zoom trinocular microscope is an advanced optical device used to magnify and inspect objects in clear three-dimensional detail while also supporting photo and video capture through an integrated camera port. Designed with dual viewing paths, it provides natural depth perception that allows users to accurately examine and manipulate larger specimens or components during observation. Its continuous zoom system lets users easily adjust magnification levels without switching lenses, while integrated detent click stops provide precise preset magnification positions that “click” into place for repeatable viewing and accurate measurement consistency during inspections or imaging tasks. The trinocular configuration includes a third optical channel dedicated to digital imaging, enabling users to record observations, perform measurements, share live demonstrations, or document results for reporting and analysis. These microscopes are widely used in electronics repair, scientific research, manufacturing, medical laboratories, education, jewelry inspection, and quality assurance because they combine precision viewing, ergonomic operation, reliable magnification control, and seamless imaging capabilities that improve accuracy, efficiency, and documentation workflows.

Description

EMZ-13TRD: Trinocular Microscope Head + MA502: Eyepieces + F: Focus Block + S-4200: Stand

EMZ-13TRD: Microscope Head with Detent
The EMZ-13TRD (with detent click-stops) 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 magnification from 3x – 420x. The large zoom range means the user can expect superb optical performance and maneuverability. The paired objectives are parfocalled and parcentered that guarantees observation of exceptionally high resolution images throughout a wide magnification range. The EMZ-13TR series offer working distances from 34mm – 252mm. The EMZ-13TRD 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-13TRD is suitable for precision-oriented semi-conductor, medical device and routine inspection. In addition to it’s 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.

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.

S-4200: Stand 
The S-4200 Boom Stand is Meiji Techno America’s most popular Ergonomic boom stand with pillar, crossarm and a 20mm drop down mounting post accepts F, FX or FC holders, (must be ordered separately) or focus blocks with a 20mm mounting hole which are commonly available from microscope manufacturers. Equipped with a 610mm (24”) vertical pole and a 530mm (20.86”) horizontal pole. The S-4200 offers minimal space requirement and greatest possible vertical post length in its series. The S-4200 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. Extra length vertical posts are available in other models. 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-4200 Boom stand provides a comfortable amount of space for preparing mice, insects and other model organisms or semiconductor and electrical components. The S-4200 is equipped by a 35 lbs. base. The S-4200 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 makes this boom stand an excellent choice in labs and production facilities.
