Marco G5 Ultra Zoom — Used Continuous-Zoom Slit Lamp Biomicroscope
The Marco G5 Ultra Zoom is the motorized continuous-zoom variant of Marco’s flagship G5 Ultra slit lamp — replacing the fixed five-step turret with a smoothly-variable 6x to 32x magnification system controlled by fingertip switches. This used marco g5 ultra zoom ships ready for clinical deployment in optometry and general ophthalmology lanes.
The Zoom configuration is preferred by clinicians who want continuous magnification adjustment during exams — useful for dialing in exactly the right view for corneal endothelium, anterior-chamber angle assessment, or fundus contact-lens biomicroscopy. The motorized zoom and motorized illumination intensity are operator-controlled via fingertip switches on the joystick base, and the illuminated magnification display window confirms the current setting at a glance. A flip-up magnification display mirror provides an additional vantage during high-throughput exams.
According to a National Library of Medicine-indexed study (Can J Ophthalmol, 2015), yellow-filtered fluorescein imaging produces clinically superior conjunctival staining contrast — the standard slit-lamp workflow the G5 Ultra Zoom was designed for.
Why Practices Choose the G5 Ultra Zoom
Continuous zoom 6x to 32x — smoothly variable magnification (not a 5-step turret) lets the clinician dial in exactly the magnification needed for the structure under examination.- Motorized zoom + illumination control — fingertip switches on the joystick base control both zoom and illumination intensity, keeping operator hands on the patient interface.
- Illuminated magnification display — backlit display window confirms current magnification setting; a flip-up display mirror provides an alternate vantage point for high-throughput workflows.
- Fingertip slit-width control — millimeter-precise slit width adjustment without releasing the joystick.
- Single-handed elevation system — Marco’s signature one-hand vertical adjustment for fast patient repositioning.
- Standard Marco optics — premium glass and broad-band illumination match the Haag-Streit 900-series optical performance class.
- Compatible with Marco beam splitters — accepts standard Marco-compatible beam splitter accessories for digital imaging integration.
- Made in USA assembly — Marco assembles the G5 family in Florida; widely supported for parts and service.
Clinical Applications
- Anterior segment evaluation — cornea, iris, lens, anterior vitreous; smoothly variable magnification optimizes for each layer.
- Corneal endothelium assessment — high-magnification (32x) views for endothelial cell health evaluation.
- Contact-lens fitting — fluorescein staining and fit assessment with continuous zoom for fast switching between overview and detail views.
- Glaucoma anterior-chamber angle — precise magnification control for AC depth and gonio observation.
- Cataract grading — direct illumination and retroillumination across the full magnification range.
- Vitreoretinal contact-lens biomicroscopy — Goldmann or Volk indirect lens evaluation of the posterior segment.
Who This Is For
- Optometry and ophthalmology practices that prefer continuous-zoom slit lamps over fixed-turret designs for finer magnification control.
- Multi-doctor groups standardizing on Marco’s premium slit-lamp platform across all lanes.
- Practices replacing an aging slit lamp and wanting a motorized-zoom unit at a sub-$6K used price point.
- Clinicians who frequently need precision magnification for endothelium or angle exams.
