Haag Streit BM 900 Slit Lamp — Used Swiss-Made Biomicroscope with AT 900 Goldmann Tonometer
The Haag Streit BM 900 slit lamp is one of the most enduring diagnostic instruments in clinical ophthalmology — Swiss-engineered, optically precise, and built to deliver reliable anterior segment examination across decades of clinical use. This used unit comes complete with the AT 900 Goldmann applanation tonometer, giving your practice a fully capable IOP measurement workstation at a fraction of the cost of new equipment. With five-step magnification from 6× to 40×, continuously variable slit illumination, and a 100 mm working distance, the Haag Streit BM 900 slit lamp handles the full spectrum of anterior segment examination in a compact, joystick-driven platform that ophthalmologists and optometrists have relied on for over 50 years. At $5,500 with a 90-day Digital Eye Center warranty, it remains one of the best-value Swiss-made slit lamps available.
Research published in the National Library of Medicine confirms the continued clinical primacy of slit lamp biomicroscopy for evaluating patients in active ophthalmic treatment, underscoring its essential role in comprehensive anterior segment care.
Why Practices Choose the Haag Streit BM 900
Swiss optical quality — Haag-Streit optical engineering delivers exceptional clarity and contrast across all five magnification steps (6×, 10×, 16×, 25×, 40×), the same optical standard this platform has maintained for over five decades.- AT 900 Goldmann tonometer included — the gold standard for intraocular pressure measurement mounts directly on the slit lamp, enabling IOP measurement without moving the patient or switching to a separate instrument.
- Halogen illumination with variable slit control — continuously variable slit width (0–14 mm) and stepped slit height support diffuse, direct focal, retroillumination, and specular reflection examination techniques across the full anterior segment.
- 100 mm working distance — comfortable patient positioning during prolonged biomicroscopy and contact lens fitting without operator fatigue.
- Camera-ready design — compatible with beam splitter adapters for anterior segment photography, documentation, and teaching; also supports the Haag-Streit Fundus Module 300 for posterior segment imaging.
- Long-established parts availability — the BM 900 platform has been in continuous production for over 50 years; bulbs, prisms, and service are widely available worldwide through Haag-Streit-authorized service networks.
- Compact joystick base — smooth XYZ positioning with joystick and elevation knob for precise alignment during biomicroscopy and tonometry without platform drift.
- Used and verified — confirmed in working order with clear optics, covered by a 90-day Digital Eye Center warranty.
Clinical Applications
- Anterior segment biomicroscopy — cornea, conjunctiva, iris, lens, and anterior vitreous examination with high-resolution optics across five magnification steps.
- Goldmann applanation tonometry — IOP measurement with the AT 900, the clinical gold standard for glaucoma screening and pressure monitoring.
- Contact lens fitting — fluorescein pattern evaluation, base curve assessment, and corneal staining documentation with broad slit control.
- Foreign body, corneal abrasion, and trauma evaluation — precise illumination control and variable magnification for anterior segment emergency assessment.
- Pre- and post-operative evaluation — anterior segment examination before and after cataract, refractive, and corneal surgery with documented clinical findings.
- Fundus imaging — when paired with the Haag-Streit Fundus Module 300, this BM 900 supports posterior segment imaging for diabetic retinopathy and optic nerve documentation.
Who This Is For
- Ophthalmology and optometry practices seeking a reliable, full-featured used slit lamp with integrated Goldmann tonometry at a cost-effective price point.
- Practices replacing aging slit lamp equipment needing a proven Swiss-made platform with decades of service infrastructure and widely available parts.
- Multi-location clinics or satellite offices equipping additional exam lanes without the cost of new instrumentation.
- Glaucoma subspecialty practices requiring integrated AT 900 Goldmann IOP measurement alongside high-quality anterior segment biomicroscopy.
