Haag Streit BD 900 — Used Single-Column Slit Lamp with Rolling Table
The Haag Streit BD 900 slit lamp is Haag-Streit’s accessible-tier clinical biomicroscope — a single-column slit lamp delivering 300,000-lux halogen illumination, continuously variable slit control, and two clinical magnification steps. The single-column architecture (in contrast to the dual-column BM 900 / BQ 900) gives broad patient access during examination. This used haag streit bd 900 ships on a rolling table for immediate clinical deployment.
The BD 900 is particularly valued by contact-lens practices for its built-in yellow filter — enabling direct fluorescein staining observation without a separate barrier filter — and its built-in C-mount video port for documentation and patient education. Slit width is continuously variable from 0 to 14 mm; magnification is 10× and 16× via the standard Haag-Streit two-step turret.
According to a National Library of Medicine-indexed study (Can J Ophthalmol, 2015), yellow-filtered fluorescein imaging produces clinically superior conjunctival staining contrast vs. unfiltered cobalt-blue alone — exactly the workflow the BD 900’s integrated yellow filter is designed for.
Why Practices Choose the BD 900
Built-in yellow filter — front-mounted yellow barrier filter for direct fluorescein contrast enhancement. Critical for contact-lens fitting evaluation, corneal staining grading, and fluorescein-enhanced applanation workflow without bolt-on accessories.- 300,000-lux halogen illumination — high-intensity halogen drive standard across the Haag-Streit 900 series. Clean color temperature for accurate fundus and anterior-segment grading.
- Continuously variable slit (0–14 mm) — full clinical range from pinpoint to wide field, with smooth manual slit-width control.
- 10× and 16× two-step magnification — standard Haag-Streit eyepiece pair; covers routine biomicroscopy and detailed corneal/anterior-chamber inspection.
- Built-in C-mount video port — direct camera attachment for documentation and patient-education imaging without add-on beam splitters.
- Single-column design — broad patient access during examination; easier to position vs. dual-column BM/BQ models, particularly with wheelchair or anxious patients.
- Rolling table included — ships ready to deploy in any exam lane; no separate stand purchase needed.
- Haag-Streit reliability — 900-series mechanical platform shared with the BM 900 and BQ 900; widely supported by independent service techs.
Clinical Applications
- Routine slit-lamp biomicroscopy — anterior-segment evaluation including cornea, iris, lens, and anterior vitreous.
- Contact-lens fitting and follow-up — built-in yellow filter delivers high-contrast fluorescein imaging for fit assessment and staining evaluation.
- Corneal disease grading — staining patterns for dry eye, recurrent erosion, ulcer, abrasion, and keratitis evaluation.
- Glaucoma anterior-chamber assessment — slit-beam evaluation of AC depth, pigment dispersion, and pseudoexfoliation.
- Cataract grading and pre-op evaluation — retroillumination and direct illumination for nuclear, cortical, and PSC assessment.
- Patient-education imaging — built-in C-mount video output captures slit-lamp images directly to a PACS or local recorder.
Who This Is For
- Optometry practices with a contact-lens-heavy workflow that need built-in yellow-filter fluorescein imaging without separate accessories.
- General ophthalmology lanes adding a second slit lamp for a junior associate or fellow at an entry-tier 900-series price.
- Multi-doctor groups standardizing on the Haag-Streit 900 mechanical platform across BD/BM/BQ tiers for consistent service and parts.
- Practices replacing an aging non-Haag-Streit slit lamp and wanting the brand reliability with a sub-$8K used unit.
