Marco Slit Lamp 2b Ultra — Used Biomicroscope with Haag-Streit 900 Tonometer
The marco slit lamp 2b Ultra combines Marco's premium Ultra Series multi-layer coated optical system with the Haag-Streit 900 applanation tonometer in a single, ready-to-use clinical workstation. Built on a Greenough converging binocular design, this marco slit lamp delivers sharper resolution, greater light transmission, and wider field of view than standard slit lamps in the same price bracket — qualities that matter in high-throughput anterior segment examination. The integrated Haag-Streit 900 is the original Goldmann applanation tonometer and the reference standard against which all other tonometers are validated. The National Library of Medicine confirms that slit-lamp biomicroscopy remains the primary clinical tool for anterior segment evaluation in ophthalmology practice.
Why Practices Choose the Marco 2b Ultra
Haag-Streit 900 tonometer included — the original Goldmann applanation tonometer; the reference instrument against which all other tonometers are validated for IOP accuracy and the gold standard for glaucoma management.- Ultra multi-layer optics — Marco's premium coating system delivers improved light transmission, higher contrast, and wider field of view versus standard slit lamps at this price point.
- Greenough converging binocular design — produces a natural, high-contrast stereoscopic image with consistent depth perception for anterior segment evaluation.
- 2-step magnification (10×, 16×) — covers routine screening through detailed lens and corneal examination; objective switching is smooth and repeatable.
- 4-filter set — cobalt blue for fluorescein and tonometry, UV, red-free for vascular contrast, and heat-absorbing for patient comfort.
- Single-hand joystick elevation — one-handed control over lateral position and height keeps examiner attention on the patient, not the instrument.
- Wide IPD range (48–80 mm) — accommodates the full spectrum of adult interpupillary distances without tools.
- Multi-voltage power supply — AC 110V/120V/220V/240V; ready to deploy internationally without a converter.
Clinical Applications
- Anterior segment examination — cornea, conjunctiva, anterior chamber, iris, and lens evaluation at 10× and 16× magnification.
- Goldmann applanation tonometry — Haag-Streit 900 IOP measurement for glaucoma screening, diagnosis, and follow-up; the clinical gold standard.
- Fluorescein staining evaluation — cobalt blue filter assesses corneal integrity, abrasions, and contact lens fit patterns.
- Gonioscopy — focused slit beam and stable base support angle assessment with a goniolens.
- Contact lens fitting — Ultra optics and smooth biomicroscope travel make this marco slit lamp well-suited for detailed contact lens evaluation.
- Posterior pole evaluation — compatible with hand-held 78 D or 90 D condensing lenses for fundus assessment at the slit lamp.
Who This Is For
- Ophthalmology practices that require a premium-grade GAT tonometer alongside a capable slit lamp without paying new-equipment prices.
- Glaucoma specialty practices where Goldmann applanation tonometry is non-negotiable and the Haag-Streit 900 is the accepted standard.
- Optometry offices seeking a mid-priced combination instrument with improved optics and a clinically validated tonometer.
- Teaching institutions where training on the Haag-Streit 900 aligns with the tonometry standard taught in residency programs.
- International practices — the multi-voltage power supply enables installation anywhere without voltage adaptation.
