Condition & Warranty
Used. The BQ 900 slit lamp has been tested and is in good working order. It has been cleaned and calibrated, the optics are clean and the lamp is lubricated. The slit lamp shows some signs of prior use. The Haag-Streit Fundus Module 300 imaging attachment is brand new and has never been used. Covered by a 90-day warranty on parts and workmanship.
Haag Streit BQ 900 — Used Slit Lamp with Fundus Module 300
The Haag-Streit BQ 900 is the flagship biomicroscope from Haag-Streit, the Swiss manufacturer that defined the modern slit lamp. This used haag streit bq 900 combines the precision of the BQ 900’s halogen illumination system and 5-step magnification changer with the Fundus Module 300 — enabling both anterior segment examination and non-contact posterior segment imaging from a single instrument. Practices that need comprehensive diagnostic capability in one footprint choose this haag streit bq 900 combination over separate instruments. A study published by the National Library of Medicine confirms fundus biomicroscopy as a validated clinical method for posterior segment evaluation, comparable to direct imaging for detecting retinal pathology during routine examination.
Why Practices Choose the Haag-Streit BQ 900
-
Fundus Module 300 (brand new) — the attached FM 300 has never been used, giving buyers a new posterior segment imaging module paired with a proven slit lamp body. Supports disc, macula, and peripheral retinal evaluation.
- 5-step magnification changer — 6×, 10×, 16×, 25×, and 40× magnification steps cover every clinical need from lid and lash inspection at low power to fine trabecular meshwork and corneal endothelium detail at 40×.
- AT 900 tonometer compatible — the BQ 900 accepts the Haag-Streit AT 900 Goldmann applanation tonometer, maintaining the gold standard for IOP measurement without replacing the slit lamp platform.
- Swiss precision build quality — Haag-Streit instruments are manufactured in Bern to tighter mechanical tolerances than most competitors, reflected in the BQ 900’s long service life and consistent optical performance over decades of clinical use.
- Single-platform workflow — combining anterior and posterior diagnostic capability into one slit lamp reduces patient chair time, room footprint, and equipment acquisition cost versus two separate instruments.

Clinical Applications
- Anterior segment biomicroscopy — detailed examination of cornea, iris, anterior chamber, and crystalline lens for cataracts, corneal dystrophies, and inflammatory disease using 6×–40× magnification and precision slit beam control.
- Non-contact fundus evaluation — posterior segment imaging with the FM 300 enables optic disc, macula, and peripheral retinal assessment without patient contact or corneal anesthesia.
- Glaucoma monitoring — anterior chamber angle evaluation, optic nerve head assessment, and Goldmann applanation tonometry (with AT 900) on one integrated platform.
- Diabetic retinopathy screening — fundus imaging with the FM 300 allows retinal evaluation in diabetic patients during routine follow-up visits.
- Post-surgical assessment — close inspection of surgical wounds, intraocular lenses, and anterior chamber anatomy following cataract or corneal surgery at 25× and 40×.
- Contact lens fitting — fluorescein pattern assessment and corneal topography evaluation using the slit lamp’s precision illumination and magnification.
Who This Is For
- Ophthalmology practices seeking a premium Swiss slit lamp with integrated fundus imaging capability at a significant discount versus new pricing.
- Optometry clinics expanding into anterior and posterior segment diagnostics with a single high-quality instrument platform.
- Academic and teaching institutions that require the diagnostic breadth of a full-featured slit lamp system with documented Haag-Streit build quality.
- Mobile and multi-location practices that benefit from the BQ 900’s self-contained design — a complete diagnostic workstation without separate posterior segment camera requirements.
