  • MA502 Eyepieces – A pair of 10× super widefield eyepieces that make the view larger and comfortable to look at.
  • FSC Focus Block – A dual-speed focusing unit that allows both coarse and fine vertical adjustments for precise focusing control.
  • BAS-3 Stand – A heavy-duty ergonomic boom support stand with a horizontal arm and vertical pillar, providing flexible positioning of the microscope head over larger work areas and specimens.

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)

What It Does

The EMZ-5TR + MA502 + FSC + BAS-3 Stand Configuration System is a high-performance stereo microscope setup tailored for demanding inspection, biological, and industrial applications. At its core is the EMZ-5TR trinocular zoom microscope head, which is designed for photography and video applications; engaging the beamsplitter directs 100 % of the available light to the phototube while still allowing a view through the eyepiece, producing high-resolution, erect, unreversed stereoscopic images with excellent flatness and contrast. The system includes MA502 Super Widefield 10× eyepieces, providing a generous field of view and comfortable eye relief for prolonged observation sessions. Supporting the optical components is the FSC focus block, an inclinable coarse and fine adjusting mount that securely holds the microscope body for precision focusing across a range of sample types. The BAS-3 Heavy Duty Boom Stand offers robust ergonomic support with a 635 mm vertical column and a 457.2 mm horizontal reach, maximizing stability even at full extension while allowing smooth horizontal movement and secure positional locking. Built to accommodate larger specimens and workflows requiring angled viewing, this configuration combines optical excellence with rugged mechanical precision for versatile use in labs, production facilities, and research environments.

Description

EMZ-5TR: Trinocular Microscope Head + MA502: Eyepieces + FSC: Focus Block + BAS-3: Boom 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 eyetube. 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
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.

FSC: Focus Block
The FSC is an inclinable coarse and fine adjusting focus block with 5/8″ diameter mounting pin to hold the stereo microscope body onto any machine or other special applications. The 84.2mm diameter opening accepts all EM Series stereo bodies.

BAS-3: Heavy Duty Boom Stand
The BAS-3 Heavy Duty Boom Stand is Meiji Techno America’s most popular Ergonomic boom stand with pillar, crossarm and a 5/8” Bonder Mount socket at the end of the horizontal arm to perfectly accept industry standard focus blocks with a 5/8” bonder pin dowel. The BAS-3 is equipped with a 635mm (25”) vertical pole and a 457.2mm (18”) horizontal pole. The BAS-3 offers minimal space requirement and greatest possible amount stability for EM Series stereo systems up to 35 lbs. There is no loss of stability even at its furthest travel. The BAS-3 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-3 Heavy Duty Boom stand provides a comfortable amount of space for microscope systems that require tilt when viewing the sample at an angle. It is designed for large biological specimens to large semiconductor and electrical components. The BAS-3 is supported by a 80.00 lbs. base. 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 make this boom stand an excellent choice in labs and production facilities.
