This instrument is versatile and easy to use while boasting the best optics in the business, making it the most popular slit lamp in top ophthalmology practices, hospitals, and teaching and government institutions. It is based on a modular system that offers digital imaging (both still photography and video) and a wide range of accessories, including teaching scopes, inclined eyepieces, and, for retinal specialists, the unique stereo variator.<\/p>\n<p>The BQ 900 slit lamp is the standard for those who require the most demanding slit lamp microscopy. Its wide range of optional accessories provides comfortable conditions for any examination.<\/p>\n<div style=\"height: 0px; overflow: hidden; padding-top: 56.25%; position: relative; width:

allowfullscreen=\"allowfullscreen\"><br \/>\n<\/iframe><\/div>\n<p>&nbsp;<\/p>\n<h2>Why Practices Choose the Haag-Streit BQ 900<\/h2>\n<ul>\n<li><strong>Flagship 900-series optical system<\/strong>\u00a0\u2014 The BQ 900 represents the highest optical specification in the Haag-Streit 900 family, with wider beam dimensions and finer optical tolerances than the BD and BM models \u2014 delivering the beam precision and contrast needed for specular reflection corneal endothelium evaluation and optical section analysis through hazy media.<\/li>\n<li><strong>LED illumination with consistent spectral output<\/strong>\u00a0\u2014 LED eliminates the progressive color shift and intensity decline of halogen bulbs, ensuring that the cobalt blue excitation, red-free vascular contrast, and white-light color rendering remain consistent across thousands of examination hours without bulb replacement.<\/li>\n<li><strong>Full slit beam control \u2014 0 to 14 mm width and height<\/strong>\u00a0\u2014 Continuously adjustable slit width and height with 180\u00b0 rotation provides the beam versatility needed for every examination technique: direct focal illumination, indirect illumination, specular reflection, retro-illumination, sclerotic scatter, and tangential illumination.<\/li>\n<li><strong>5-step magnification from 6\u00d7 to 40\u00d7<\/strong>\u00a0\u2014 Wide magnification range supports diffuse anterior segment survey at 6\u00d7, routine biomicroscopy at 10\u00d7\u201316\u00d7, and high-power endothelial examination at 25\u00d7\u201340\u00d7 \u2014 with smooth magnification steps that do not require refocusing when changing power.<\/li>\n<li><strong>Compatible with AT 900 Goldmann tonometer<\/strong>\u00a0\u2014 The BQ 900 accepts the AT 900 applanation tonometer as an optional add-on, enabling practices to configure the instrument with or without tonometry depending on examination lane requirements.<\/li>\n<li><strong>Documentation and photography ready<\/strong>\u00a0\u2014 The BQ 900 platform supports slit lamp camera adapters and beam splitter attachments for anterior segment photography and videography \u2014 making it the preferred base instrument for practices adding slit lamp documentation capability.<\/li>\n<li><strong>Long service life with full parts support<\/strong>\u00a0\u2014 The Haag-Streit 900 platform has been in continuous production since 1959; parts, service manuals, and qualified technicians are available worldwide \u2014 making the BQ 900 one of the most supportable ophthalmic instruments available regardless of instrument age.<\/li>\n<\/ul>\n<div><\/div>\n<h2>Klinische Anwendungen<\/h2>\n<ul>\n<li><strong>Corneal disease diagnosis and monitoring<\/strong>\u00a0\u2014 Optical section illumination reveals epithelial, stromal, and endothelial pathology; specular reflection shows endothelial cell density and polymegethism; retro-illumination highlights anterior subcapsular opacities and corneal dystrophy deposits with clarity that lower-quality slit lamp optics cannot match.<\/li>\n<li><strong>Dry eye and ocular surface assessment<\/strong>\u00a0\u2014 Cobalt blue illumination with fluorescein sodium visualizes corneal staining patterns, meibomian gland dysfunction evaluation, and tear film break-up time across the full exposure zone \u2014 the foundation of every dry eye work-up and treatment monitoring protocol.<\/li>\n<li><strong>Anterior segment examination<\/strong>\u00a0\u2014 Standard slit lamp biomicroscopy of the eyelids, conjunctiva, cornea, anterior chamber, iris, and crystalline lens forms the basis of every comprehensive ophthalmic examination \u2014 including nuclear sclerosis grading, angle estimation, and anterior vitreous assessment.<\/li>\n<li><strong>Contact lens fitting and management<\/strong>\u00a0\u2014 White-light biomicroscopy for lens centration, fluorescein pattern assessment for RGP and scleral lens fit, and corneal staining grading for contact lens\u2013related complications require the optical quality and beam precision that the BQ 900 provides.<\/li>\n<li><strong>Posterior segment with auxiliary lenses<\/strong>\u00a0\u2014 Combined with a non-contact fundus lens (78D, 90D) or contact lens, the BQ 900 enables indirect slit lamp biomicroscopy of the optic disc, macula, and peripheral retina \u2014 providing posterior segment access in every exam lane.<\/li>\n<li><strong>Anterior segment documentation<\/strong>\u00a0\u2014 With a camera adapter or beam splitter, the BQ 900 provides the base for slit lamp photography of corneal pathology, anterior chamber findings, and iris abnormalities for medical record documentation, patient education, and publication.<\/li>\n<\/ul>\n<div><\/div>\n<h2>Who This Is For<\/h2>\n<ul>\n<li><strong>Corneal and external disease specialists<\/strong>\u00a0\u2014 the BQ 900\u2019s optical precision, LED cobalt blue filter, and documentation compatibility make it the instrument of choice for subspecialty corneal examination and disease management that demands the highest slit lamp image quality.<\/li>\n<li><strong>Dry eye and ocular surface practices<\/strong>\u00a0\u2014 high-volume dry eye clinics performing repeated fluorescein staining documentation benefit from the LED\u2019s consistent spectral output and long bulb life compared to halogen systems that require frequent bulb changes in a busy examination schedule.<\/li>\n<li><strong>Comprehensive ophthalmology and optometry practices<\/strong>\u00a0equipping an additional exam lane with the same reference-standard optical quality as their primary instrument \u2014 the BQ 900 eliminates the optical quality variation between lanes that lower-tier instruments introduce.<\/li>\n<li><strong>Practices adding slit lamp documentation<\/strong>\u00a0\u2014 the BQ 900\u2019s camera-adapter compatibility makes it the logical base instrument for practices planning to add anterior segment photography without purchasing a separate photo slit lamp.<\/li>\n<li><strong>Residency and fellowship training programs<\/strong>\u00a0\u2014 training on the\u00a0<strong>Haag-Streit BQ 900<\/strong>\u00a0platform ensures that trainees develop slit lamp technique on the same instrument they will use throughout their careers, as the 900-series is the reference standard in virtually every academic ophthalmology training program.<\/li>\n<\/ul>\n<div><\/div>\n<h2>Technische
