Optical Performance
Zoom range: 0.7×–4.5× continuous zoom (6.5:1 ratio) for smooth magnification changes without refocusing
Standard magnification: ~7×–45× when used with required 10× high eyepoint eyepieces
Working distance:104 mm, providing plenty of space for tools and manipulation under the lens
Optical design: Greenough stereo optics deliver high contrast, flat field, and true 3D depth perception with bright edge performance
Parfocal zoom: Focus remains stable throughout the zoom range
What It Does
Stereo zoom trinocular microscopes with high‑eyepoint eyepieces are designed for applications requiring highly detailed, three-dimensional observation of objects while maintaining a comfortable working distance and the ability to manipulate items under the lens. They are widely used in electronics inspection and repair, allowing precise examination of circuit boards, solder joints, and small components, as well as in precision assembly and manufacturing, where accurate alignment and placement of tiny parts are critical. These microscopes are also ideal for quality control, metrology, and defect analysis, enabling operators to detect subtle surface features and irregularities. The trinocular design allows simultaneous camera attachment for documentation or instructional purposes without interrupting the live view, while the high-eyepoint eyepieces provide comfortable viewing for users with glasses and reduce eye strain during extended use. Additional applications include medical device inspection, educational demonstrations, jewelry making, watchmaking, and other hands-on tasks where both fine visual detail and space to work under the objective are essential.

NOTE: The versatility of a Meiji Techno Stereo Microscope is the ability to pick from a wide range of components to adapt to your unique application: • Stereo Microscope Body (Zoom, Turret or Fixed) • Eyepieces (Requires 2 of identical magnification) • Stand (Pole stands, rigid arm stands, boom stands, heavy duty boom stands, wide surface stands or articulated arm stands) • Illumination Source (Fiber optic halogen, fiber optic LED, fluorescent ring or LED illumination) • Auxiliary Lens (Optional)
EMZ-8TRH: Trinocular Microscope Head + MA522: Eyepieces + P: Stand + MA961W/80/ESD: Illuminator
EMZ-8TRH: Microscope Head The EMZ-8TRH 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-8TRH Trinocular High Eyepoint with 0.7x-4.5x zoom ratio offers direct light to all three viewing ports simultaneously. The EMZ-8TRH is designed for high-contrast images and has an excellent zoom range of 6.5:1 that is parfocalled all throughout the zoom range. It has Greenough optics for improved image flatness and contrast which results in brighter images at the periphery of the field of view. The EMZ-8TRH offers erect unreversed stereoscopic images providing high resolution observation in precision-oriented semi-conductor, medical device and routine inspection.
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)
P: Stand The P stand in Meiji Techno America’s basic pole stand with “F” focusing holder mounted on a plain base. It accepts our EMZ, EMT and EMF stereo microscope bodies. It is supplied with a 94.5mm diameter reversible black and white stage plate with a locking pin, two stainless steel stage clips and a 20mm diameter vertical pole. The P stand’s compact design allows users to maximize their work area, so that operation in limited space becomes possible. Since there is no built-in illumination, it allows the end-user to select from a variety of incident light options from an LED ring light to a dual arm fiber optic system.
MA961W/80/ESD: Warm LED The MA961W/80/ESD is designed with an inner and outer quadrant warm white LED ring populated by 80 high quality, extremely bright, which can be controlled in 8 segmented white LEDs. The inner and outer rings of LED’s are set at different angles to create uniform illumination across a wide range of working distances. The MA961W/80/ESD it has 3000K illumination. Each ring and LED segment can be independently controlled using advanced eight segment LED controller. Dual dimming controls provide maximum color stability at all dimming levels. CNC-machined from a solid block of aluminum alloy allowing optimal thermal management and performance in a rugged attractive package. The MA961W/80/ESD comes standard with a universal power source for worldwide operation.

MA961W/80/ESD: Ring Illuminator
The MA961/80 line features 80 powerful and precision aligned LEDs for shadow free illumination across a wide range of working distances. Dual dimmers and up to 8 separately controllable banks provide excellent control over the illumination. The proprietary controller is designed for durability and to provide a DC supply that eliminates flicker or strobing effects. An auto voltage sensing 100 – 240 VAC power supply is included.
The M961/80/ESD Safe models are carefully constructed by starting with an aluminum alloy that is precision machined. These parts are then subjected to a multi-step proprietary coating process that both protects the alloy and preserves surface electrical conductivity.
