  • Sharp, high-contrast stereo images
  • Excellent depth of field for 3D specimen viewing

What It Does

Stereo zoom trinocular microscopes are typically used for low-magnification, high-detail viewing of solid objects in 3D while allowing hands-on work and image capture, making them common in applications like electronics assembly and circuit board inspection, dissection and biological study, jewelry and watch repair, industrial quality control, forensic analysis, and microsurgery—where users need depth perception, adjustable zoom, and the ability to record photos or video through the trinocular port.

Description

EMZ-13TRH: Trinocular Microscope Head + MA522: Eyepieces + FS: Focus Block + S-4300: Stand

EMZ-13TRH: Microscope Head
The EMZ-13TRH is a new and improved high eyepoint model with an eye relief of 20.9mm designed for microscopists and for people who wear glasses. It is specially designed to give the user more clearance between their eyes and the microscope. The high eyepoint models also use a newly designed eyepiece with a wider designed lens to compliment the high eyepoint models (MA522 10X, MA818 15X, MA819 20X). Optional rubber eye guards (MA906) are also available. The EMZ-13TRH 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 a magnification from 3x – 420x. Because it has a large zoom range, the user can expect superb optical performance and maneuverability. The paired objectives are parfocalled and parcentered which guarantee observation of high resolution images throughout a wide magnification range. The EMZ-13TRH series offer working distances from 34mm – 252mm. The EMZ-13TRH 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-13TRH is suitable for 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 work/lab application.

MA522: Eyepieces 
MA522 Super Widefield Eyepiece is included, high eye point 10X (paired) (With 25mm reticle mount) (Fits EMZ-5H, EMZ-5TRH, EMZ-8TRH, EMZ-10H models only)

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-4300: Stand 
The S-4300 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-4300 offers minimal space requirement and greatest possible amount of work room. The S-4300 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-4300 Boom stand provides a comfortable amount of space for preparing mice, insects and other model organisms or semiconductor and electrical components. The S-4300 is equipped by a 35 lbs. base. The S-4300 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.
