The surgeon never touches the eye without looking through it first. Image quality, red-reflex brightness, and depth perception through the oculars directly determine how safely the surgeon completes each step. 1 Bright, centred coaxial illumination Strong red reflex for capsulorhexis & cortex clean-up 2 Stereoscopic binocular optics True depth perception near retina & lens capsule 3 Smooth, precise zoom & focus Overview to high-mag detail without breaking rhythm 4 Stable XY positioning Tracks the field without drift in long VR cases 5 Ergonomic eyepiece & arm design Reduces surgeon fatigue across a full operating list 02 P A R T 1 · T H E M I C R O S C O P E I N 2 M I N U T E S Anatomy of a Surgical Microscope Every AAMO model shares this optical chain — know it to diagnose almost any complaint on demo day. 1 Objective Lens Faces the patient's eye; focal length (F=200mm typical) sets working distance 2 Zoom Changer Manual step or motorized continuous — typically 0.4x to 2.4x/2.5x 3 Binocular Tube & Eyepieces Splits image to both eyes for stereopsis; usually 10x wide field 4 Illumination System Coaxial LED creates red reflex; oblique light illuminates the field 5 XY Coupling Repositions the field of view without moving the whole head 6 Focus Mechanism Motorized or manual, ~50mm range, usually foot- controlled 03 P A R T 2 · T H E A A M O P R O D U C T L I N E Choosing the Right Model Match the model to the surgeon's case mix and budget — one philosophy, three tiers.

A coaxial LED beam is folded into the same path, producing a bright, centred red reflex. In short: a stereoscopic, brilliantly illuminated, precisely focused view of a structure a few millimetres across — from a comfortable working distance. Objective Lens Sets working distance (F=200mm typical) → Illumination Dual LED — coaxial (red reflex) + oblique → Zoom Changer Higher zoom = finer detail, smaller field → Binocular Tube Tiltable for comfortable neck posture → XY Coupling Repositions view within a 61mm stroke → Filters Yellow/blue/retinal-guard cut phototoxicity 05 P A R T 3 · H O W T H E S Y S T E M W O R K S Key Technical Parameters — Know These Cold 10x Eyepiece (12.5x optional) — sets apparent field size 200mm Objective focal length (175/225mm optional) 0.4x–2.5x Magnification range across the AAMO line 1:6 Motorized continuous zoom ratio (Truglow FS-1) 61mm XY coupling stroke, X and Y 50mm Motorized focus range +8 to −8 Diopter adjustment, per eyepiece 55–75mm Interpupillary distance (IPD), adjustable Power supply: ~110–230V, 50–60Hz, 50VA — confirm mains compatibility before every install or demo. 06 P A R T 4 · D E M O D A Y Setup Sequence — Before the Surgeon Sits Down A smooth demo is silent competence.
