Optical System

Adopting premium-grade optical performance with an apochromatic full-optical-path lens design. It delivers outstanding balance across resolution, sharpness, depth of field and color reproduction by combining high resolving power and extended depth of field. (Constructed with SCHOTT optical glass; no blue fringing on light spot)

Working Distance

With standard single adjustable objective lens: minimum working distance ≤200 mm, maximum working distance ≥600 mm; optional configuration available: min. working distance≤215 mm, max. working distance ≥650 mm.

Magnification Range

Fitted with 12.5× eyepieces: native magnification spans from ≤2× minimum to ≥22× maximum. Magnification can reach ≥40× when coupled with manufacturer-matched auxiliary magnification booster. Featuring a 1:6 continuous stepless optical zoom with both motorized and manual adjustment modes. Real-time parameters including magnification, working distance and illumination brightness can be displayed on monitor screen.

Extended Depth-of-Field Design (3-stage adjustable depth enhancement mode)

Superior depth-of-field performance cuts down frequent intraoperative fine adjustments; effective DOF is 30% higher than mainstream competing products.

Zoom Memory Function

Intelligent zoom preset function saves current magnification status, enabling one-touch toggle between maximum magnification and stored working magnification; adjustable zoom coefficient allows flexible magnification fine-tuning. (High-end standard configuration equivalent to Carl Zeiss K900 & P800S surgical microscope series)

Dual-Laser Autofocus Function

Two visible red laser markers are provided. Upon releasing the electromagnetic lock, the system executes automatic focusing without any manual intervention.

Stellar Iris Precision Focus Control System

Customizable shortcut keys on the control handle enable ultra-fine focusing adjustment down to ≤0.3 mm, catering to stringent intraoperative fine-tuning on depth of field and focal distance in microsurgery, and securing crisp surgical field imaging and precise manipulation.

One-Touch White Balance

Optimizes color rendition and tone calibration to deliver accurate, secure visual observation for surgical procedures.

Eyepieces

Wide-field eyepieces with height-adjustable eye cups; standard 12.5× specification, diopter compensation range ±6 D (upgraded to ±8 D in 2026).

Assistant Scope

Dual-articulated assistant scope with full 360° rotational adjustment.

Fine Focus Knob

A precision focusing dial is mounted directly on the optical probe head.

Eyepiece diopter: +6D/-6D

Picture-in-Picture Function

Supports simultaneous quad-view display of four imaging modalities: white light mode, monochrome fluorescence mode, augmented reality (AR) fluorescence mode, and color-mapping fluorescence mode. Any single image can be switched to full-screen main view, offering versatile observation options to satisfy surgeons’ multi-layer intraoperative visualization requirements.

Hybrid Opto-Digital Imaging System

Apart from traditional optical eyepiece viewing, Hai Hong surgical microscope adopts built-in dual-path native 4K‑3D exoscope technology instead of standalone 3D cameras. Leveraging full-depth sensing and high-resolution optics, the system renders naturally colored tiny anatomical details across an extensive field via a dedicated 4K‑3D monitor and delivers ultra-high-definition immersive visualization. Users can freely toggle between eyepiece direct viewing and external screen-guided surgery, pioneering innovative surgical visualization.

Similar to watching a 3D movie with polarized glasses, the operating surgeon and surgical team wear circular polarized 3D spectacles for stereoscopic vision; nursing staff normally view on the 2D display without 3D eyewear. Equipped with left/right circular polarizing lenses, the 3D glasses separate paired stereoscopic image signals for respective eyes, which the human brain fuses into a three-dimensional view with optimal depth of field — a critical advantage for precision surgical procedures.
