YZ20T4 Ophthalmic, hand surgery operation microscope (112 LP/mm, cold halgon Coaxial:≥50000lx, Oblique:≥45000lx, 2.7x ~ 25x)
YZ20T4 Ophthalmic & Hand Surgery Operation Microscope — CE & FDA Certified
Product Code: YZ20T4
Product Overview
The YZ20T4 is a premium double binocular operation microscope engineered for two surgeons working simultaneously. Its assistant binocular can be quickly switched to serve as an opponent binocular, making it an exceptionally versatile solution for ophthalmic surgery and hand surgery. With outstanding 112 LP/mm resolution and powerful dual illumination, this microscope delivers the clarity and precision your surgical team demands.
Key Features & Benefits
- Dual-Surgeon Flexibility: Assistant microscope can be rotated to function as an opponent microscope, enabling seamless collaboration between the primary and assisting surgeon.
- Integrated Teaching & Documentation: Internal beam splitter can be connected to a teaching tube and CCD system for live observation, recording, and training.
- Three Objective Lenses Included (f200/f250/f300): One microscope covers ophthalmic surgery, orthopedic surgery, and hand surgery — no need for multiple units.
- Versatile Oblique Illumination: Functions as slit illumination with adjustable slit width, giving you precise control for delicate procedures.
- Superior Optical Resolution: 112 LP/mm maximal resolution ensures sharp, high-contrast visualization of fine anatomical structures.
- Powerful Cold Halogen Illumination: Coaxial illumination ≥50,000 lx and oblique illumination ≥45,000 lx for bright, clear views with minimal heat.
- Wide Magnification Range: 2.7x to 25x magnification for everything from wide-field orientation to high-detail inspection.
Ideal Applications
- Ophthalmic Surgery: Anterior and posterior segment procedures requiring high magnification and coaxial illumination.
- Hand Surgery: Microvascular anastomosis, nerve repair, and tendon reconstruction.
- Orthopedic Surgery: Fine bone and soft tissue work requiring precision optics.
- Teaching Hospitals & Training Centers: Beam splitter and CCD compatibility make it ideal for live demonstrations and surgical education.
