Haag Streit BP 900 LED Slit Lamp — Used 900-Series Biomicroscope with AT 900 Tonometer

The Haag Streit BP 900 is a 900-series slit lamp biomicroscope featuring LED illumination and integrated AT 900 Goldmann applanation tonometer — delivering the optical performance and IOP measurement precision that the Haag-Streit 900 platform has set as the clinical reference standard for over six decades. This used Haag Streit BP 900 comes with a mounted AT 900 tonometer, providing a complete slit lamp and tonometry workstation with the LED upgrade that eliminates the color shift and heat output of halogen illumination for truer tissue color rendering and longer lamp life.

The Haag Streit BP 900 slit lamp delivers the narrow slit beams, optical section illumination, and diffuse illumination modes needed for comprehensive anterior segment examination — from corneal endothelium evaluation to crystalline lens grading, angle estimation, and vitreous examination with appropriate lenses. A multicentre randomised clinical trial published in the British Journal of Ophthalmology (National Library of Medicine, 2019) confirmed the accuracy of Goldmann applanation tonometry and its correlation to corneal biomechanical parameters — directly validating the AT 900 Goldmann tonometer that ships with this Haag Streit BP 900 as the IOP measurement gold standard in clinical glaucoma care.

Why Practices Choose the Haag Streit BP 900

• LED illumination with true color rendering — The LED light source eliminates the yellow-orange color shift of aging halogen bulbs, maintaining consistent white balance across the illumination field for accurate tissue color assessment — critical for iris transillumination, corneal staining pattern interpretation, and disc color evaluation with auxiliary lenses.
• 900-series optical platform — Haag-Streit’s 900-series optics are the reference standard against which all other slit lamp optical systems are measured; the beam control, slit width precision, and magnification steps are the same platform used in academic medical centers and subspecialty training programs worldwide.
• AT 900 Goldmann applanation tonometer included — The AT 900 is the Goldmann tonometer that the WHO designates as the reference standard for clinical IOP measurement; having it mounted and calibrated as a unit with the slit lamp eliminates the per-exam setup time and calibration variability of tonometer attachment systems.
• Full slit beam control — Continuous width adjustment from 0 mm (fully closed) to 14 mm (fully open), with height adjustment and angular rotation, provides the beam control needed for optic section examination, specular reflection assessment, and indirect focal illumination in any anterior segment structure.
• 5-step magnification from 6× to 40× — Wide magnification range from low-power diffuse survey to high-power endothelial examination covers every anterior segment examination requirement without instrument changes.
• Proven long-term durability — Haag-Streit 900-series slit lamps are routinely maintained and refurbished across 20–30 year service lifespans; the mechanical and optical platform has essentially unchanged since the 1950s, meaning parts availability and service support are better for this platform than for any alternative.

Clinical Applications

• Intraocular pressure measurement — The mounted AT 900 Goldmann tonometer delivers the reference-standard IOP measurement required for glaucoma diagnosis, treatment monitoring, and suspect management — performed at the slit lamp without repositioning the patient.
• Anterior segment examination — Full slit beam examination of the cornea (epithelium, stroma, endothelium), anterior chamber (depth, cells and flare), iris, lens (nuclear sclerosis grading, cortical spoke assessment, PSC evaluation), and anterior vitreous.
• Corneal disease evaluation — High-resolution optical section imaging of corneal pathology: keratoconus evaluation, corneal dystrophy characterization, post-surgical flap assessment, corneal edema grading, and fluorescein staining pattern documentation.
• Contact lens fitting and follow-up — Slit lamp biomicroscopy is the primary tool for assessing contact lens fit, corneal staining patterns, and contact lens–related complications — the optical quality of the 900-series optics provides the detail needed for soft, RGP, and scleral lens management.
• Posterior segment examination with auxiliary lenses — Combined with a 78D, 90D, or Volk lens, the BP 900 provides indirect biomicroscopy of the optic disc, macula, and peripheral retina — enabling posterior segment examination in any exam lane without a separate indirect ophthalmoscope.
• Anterior segment procedures — Slit lamp guidance for anterior chamber paracentesis, intravitreal injection, anterior vitrectomy, and laser contact lens procedures; the stable joystick-controlled platform provides the precision required for slit lamp–guided procedures.

Who This Is For

• Ophthalmology practices adding a second or third slit lamp exam lane — the Haag Streit BP 900 with AT 900 provides the reference-standard exam platform for high-volume practices where multiple concurrent exam lanes are needed to support surgical pre- and post-operative workflows.
• Glaucoma-focused practices requiring reliable Goldmann IOP at every lane — the mounted AT 900 ensures that every IOP measurement is taken on the same reference-standard instrument regardless of which exam room the patient is in.
• Optometry practices upgrading to LED illumination — LED eliminates recurring halogen bulb replacements and provides consistently accurate color rendering for anterior segment documentation and staining evaluation that halogen illumination cannot match.
• Teaching programs and residency training — The Haag-Streit 900-series platform is the instrument residents and fellows train on at every major ophthalmology training program; using it in a community practice environment ensures that training-site competencies transfer directly.
• Practices replacing aging 900-series units — the LED upgrade on this Haag Streit BP 900 extends the useful service life of the instrument well beyond a comparable halogen unit while maintaining the same familiar 900-series operating ergonomics and controls.
