Haag Streit BM 900 Slit Lamp — Used with AT 900 Tonometer and Rolling Table

Research published in the National Library of Medicine confirms that Goldmann applanation tonometry remains the reference standard for intraocular pressure measurement in clinical practice, making the AT 900 a validated and widely accepted component of comprehensive ophthalmic examination workflows.
Why Practices Choose the Haag Streit BM 900 Slit Lamp
Proven Haag-Streit optical platform — the BM 900 delivers the illumination consistency and image quality that Haag-Streit is known for across ophthalmic and optometric practices worldwide; anterior segment examination from corneal epithelium to anterior vitreous with the same optical system found in academic and high-volume clinical settings.
- Two-step magnification (10× and 16×) — the BM 900’s standard magnification steps cover routine biomicroscopy through detailed anterior segment assessment; optional 25× and 40× eyepieces extend the range for practices requiring higher magnification for fine anterior segment work.
- Blue, red-free, and grey filters — the BM 900 filter set supports fluorescein tear film and contact lens assessment (blue filter), red-free nerve fiber layer and retinal vessel evaluation (green filter), and neutral density viewing (grey filter); the full clinical filter set for standard anterior segment examination is included.
- Continuous slit adjustment 0–8mm width and height — full slit range from pinpoint to 8mm slit beam with continuous adjustment; slit rotates ±90° and swings horizontally ±90° and vertically 0–20° for oblique and specular illumination techniques without repositioning the patient.
- Single-handed 3D joystick operation — the BM 900 instrument base moves 100mm in length, 100mm laterally, and 30mm in height from a single joystick; the examiner controls slit lamp positioning without removing focus from the eyepieces, supporting efficient exam workflows in busy lanes.
- AT 900 Goldmann applanation tonometer integrated — the AT 900 mounts directly to the BM 900 column for seamless transition from biomicroscopy to IOP measurement at the same instrument position; Goldmann applanation tonometry without a separate instrument or patient repositioning.
- Rolling table — complete mobile station — the locking-caster rolling table creates a self-contained BM 900 exam station that positions in any room without fixed installation; practices add slit lamp capacity to procedure rooms, satellite offices, and secondary lanes without construction or hard-wired exam lane build-out.
- Used pricing with 90-day warranty — complete BM 900 station at $8,580 includes slit lamp, tonometer, and rolling table with a 90-day warranty on parts and workmanship.
Clinical Applications
- Anterior segment biomicroscopy — corneal, epithelial, stromal, and endothelial examination; anterior chamber depth and cell assessment; crystalline lens evaluation and anterior vitreous inspection across routine comprehensive and specialty ophthalmic examination workflows.
- Goldmann applanation tonometry — AT 900 IOP measurement for glaucoma screening, diagnosis, and treatment monitoring; the reference standard IOP technique integrated into the slit lamp examination without a separate instrument or additional lane equipment.
- Contact lens fitting and monitoring — blue filter fluorescein pattern assessment for rigid lens fitting; slit lamp evaluation of soft lens centration, movement, and corneal health during contact lens practice workflows.
- Multi-room and procedure room deployment — rolling BM 900 station provides slit lamp capability wherever it is positioned; anterior segment examination and IOP measurement available in procedure rooms, post-op areas, and satellite exam rooms without a fixed installation in each.
- Fluorescein and anterior segment assessment — blue filter for tear film evaluation, punctate epithelial erosion detection, and fluorescein staining patterns; red-free filter for nerve fiber layer and anterior segment vessel assessment.
- Practice expansion without fixed lane investment — the rolling station adds slit lamp examination capacity to any room without exam lane construction; practices increase throughput or add locations with a mobile station rather than a full lane build.
Who This Is For
- Multi-room ophthalmology and optometry practices needing slit lamp access in more than one location — exam rooms, procedure areas, satellite offices — without fixed lane installation in each space; the rolling BM 900 station covers multiple rooms from a single instrument.
- Practices adding examination capacity to secondary rooms or procedure areas without the expense of a second fixed exam lane; the rolling station delivers full anterior segment and IOP capability anywhere it is positioned.
- Practices sourcing a complete slit lamp station in one purchase — BM 900 biomicroscope, AT 900 tonometer, and rolling table arrive together at $8,580, eliminating the need to source table and instrument separately.
- Practices replacing aging slit lamp furniture or equipment where the BM 900 platform provides a reliable used Haag-Streit instrument at below-new pricing with a 90-day warranty.
