Haag Streit BD 900 — Used Slit Lamp with AT 900 Goldmann Applanation Tonometer
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 (0–14 mm), and two clinical magnification steps paired with a built-in yellow filter designed for fluorescein-enhanced examinations. This used haag streit bd 900 is configured with the Haag-Streit AT 900 Goldmann applanation tonometer, providing a complete anterior segment and IOP measurement workstation at used-equipment pricing. 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 single-column design that allows broad patient access during examination. Research published in the National Library of Medicine confirms the accuracy of Goldmann applanation tonometry with fluorescein as the reference standard for intraocular pressure measurement — validating the combined IOP and biomicroscopy workflow that the haag streit bd 900 with AT 900 is specifically designed to deliver.
Why Practices Choose the Haag Streit BD 900
Built-in yellow filter — the BD 900 includes a built-in yellow barrier filter positioned at the front of the microscope for direct fluorescein contrast enhancement; essential for contact lens fitting evaluation, corneal staining assessment, and fluorescein-enhanced Goldmann applanation tonometry without additional filter accessories.- 300,000-lux halogen illumination — single-column illumination arm delivers up to 300,000 lux at the slit; illumination intensity is continuously adjustable via a control positioned directly adjacent to the joystick for ergonomic single-handed operation during patient examination.
- AT 900 Goldmann applanation tonometer — the clinical gold standard for IOP measurement; mounts directly to the BD 900 column for seamless transition from anterior segment biomicroscopy to Goldmann applanation tonometry without patient repositioning or instrument changes.
- Two-step magnification (10× and 16×) — flip-lever magnification selection provides two clinical levels: 10× for broad anterior segment survey and 16× for detailed corneal, lens, and anterior chamber examination at standard clinical working distances.
- C-mount video port — built-in video output port optimized for the Haag-Streit CM 900 camera and compatible with any standard C-mount imaging system; enables slit lamp photography and documentation without external beam-splitter adaptation.
- Continuously variable slit (0–14 mm) — full-range slit width and height control for optical section, corneal evaluation, cell and flare grading, and contact lens staining pattern documentation.
- Single-column design for patient access — the BD 900’s single illumination column maximizes examiner access to the patient, particularly for slit lamp procedures requiring lateral approach such as gonioscopy and fundus lens biomicroscopy.
- Used pricing with Haag-Streit quality — the BD 900 at $8,690 used delivers Haag-Streit optical quality and Swiss manufacturing precision at significantly below new-equipment pricing, with a 90-day warranty.
Clinical Applications
Contact lens fitting and evaluation — the BD 900’s built-in yellow filter enables direct fluorescein staining pattern assessment for rigid gas-permeable fitting, soft lens corneal staining evaluation, and contact lens-related complication detection without additional filter accessories.- Goldmann applanation tonometry — AT 900 IOP measurement for glaucoma screening, diagnosis, monitoring, and treatment response assessment; fluorescein-enhanced tonometry with the built-in yellow filter for optimal mire visualization.
- Anterior segment biomicroscopy — corneal epithelium, stroma, and endothelium examination; anterior chamber depth and cell/flare assessment; crystalline lens and IOL evaluation; routine comprehensive eye examination slit lamp work.
- Corneal disease examination — assessment of corneal pathology including edema, ulceration, dystrophies, and post-surgical changes using slit lamp optical section, specular reflection, and diffuse illumination techniques.
- Pre- and post-operative assessment — anterior segment documentation for cataract, refractive, and corneal surgery patients requiring slit lamp examination of pre-operative status and post-operative outcomes.
Who This Is For
- Contact lens practices — the BD 900’s built-in yellow filter and 14 mm slit are specifically valued for contact lens fitting and corneal surface evaluation; the most direct feature differentiator compared to other 900-series models.
- Ophthalmology practices adding or replacing a lane — the BD 900 with AT 900 at $8,690 equips an additional exam lane with complete Haag-Streit anterior segment biomicroscopy and Goldmann IOP measurement at the lowest price point in the 900 series.
- Optometry practices performing Goldmann tonometry — for ODs equipped to perform GAT, the BD 900 with AT 900 delivers Haag-Streit build quality and integrated tonometry at used pricing.
- Glaucoma monitoring practices — the AT 900 at a Haag-Streit slit lamp provides the reference-standard platform for serial IOP monitoring; the BD 900 supports high-volume glaucoma patient workflows without compromise on measurement accuracy.
- Budget-conscious practices who want Haag-Streit — the BD 900 is the accessible entry point into the Haag-Streit 900 series, delivering the same Swiss-precision manufacturing and optical quality at below-BQ 900 pricing.
