EMZ-8TRU + MA502 + FS + S-4400, Stereo Zoom Trinocular Stand Configuration System, Magnification (0.7X-0.45X), W.D. 104mm (4.1″)

Key Components

  • EMZ-8TRU Trinocular Head with Top Light Port – 360° rotatable zoom head with simultaneous 3-port viewing and a fiber-optic top-light inlet aligned to the optical axis
  • MA502 Eyepieces – Pair of 10× Super Widefield eyepieces that deliver a broad, clear view.
  • FS Focus Block – A rack‑and‑pinion focus holder that lets you adjust focus smoothly and precisely with coarse focus control.
  • S-4400 Stand – An ergonomic boom stand with long vertical and horizontal arms, allowing flexible positioning and good reach over samples.

Optical Performance

  • Zoom Range: 0.7× – 4.5× (zoom ratio ~6.5:1)
  • System Magnification: ~7× to 45× with 10× eyepieces 
  • Working Distance: 104 mm (4.1 in)
  • Parfocal zoom design keeps the image in focus while changing magnification
  • Greenough stereoscopic optics deliver high contrast, improved image flatness, and bright edge-to-edge viewing
  • Erect, unreversed 3D image output for natural depth perception and orientation

What It Does

Trinocular microscopes with a top light port are used for detailed 3D inspection, documentation, and surface analysis of small objects, especially when both viewing and recording are important. The trinocular design lets a user observe through the eyepieces while a camera simultaneously captures images or video, which is useful in research, teaching, quality control, and repair work where findings need to be saved or shared. The top light (incident illumination) shines light directly onto the sample’s surface, making it much easier to see fine surface details like scratches, cracks, textures, solder joints, or reflective features that wouldn’t be visible with light coming from below. Because of this combination, these microscopes are widely used in electronics inspection, manufacturing, materials science, forensic work, and biological labs—any situation where you need clear magnified views, accurate surface detail, and the ability to document what you see.

Description

EMZ-8TRU: Trinocular Microscope Head + MA502: Eyepieces + FS: Focus Block + S-4400: Stand

EMZ-8TRU: Microscope Head
The EMZ-8TRU zoom body offers direct light to all three viewing ports simultaneously. The EMZ-8TRU has a special inlet for a single arm fiber optic light guide which allows illumination to be paralleled to the optic path which are designed for observing objects that are normally difficult to see under oblique incident-light illumination such as holes or cracks, scratches on metal surfaces, IC chips and liquid crystal patterns. The EMZ-8TRU is designed for high-contrast images and an excellent zoom range of 6.5:1 that is parfocalled all throughout the zoom range. The EMZ-8TRU includes Greenough optics for improved image flatness and contrast which results in brighter images at the periphery of the field of view. The EMZ-8TRU offers erect and unreversed stereoscopic images as well. Its modular versatility complements a wide variety of auxiliary lenses and stands that are available to allow users to customize their desired working distance 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.

FS: Focus Block 
The FS Coarse Focus Block/Holder is a tilting focus holder with an integral adjustable illuminator port. It has a rack and pinion mount that allows smooth and precise focusing over 55mm of travel. The coarse focus mechanism incorporates a slip clutch and tension adjustment.

S-4400: Stand 
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 stablilized 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 an 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.
