Topcon SL-6E Slit Lamp Used — Anterior Segment Biomicroscopy with Optilasa Tonometer
The Topcon SL-6E slit lamp is a full-size tabletop photo biomicroscope built for precise anterior segment examination in a busy clinic. This Topcon SL-6E slit lamp pairs a Galilean-type binocular microscope with a five-step revolver-drum magnification changer and a continuously variable slit beam, giving clinicians high-contrast stereoscopic detail of the cornea, iris, lens, and anterior vitreous. The package includes an Optilasa applanation tonometer so anterior segment evaluation and intraocular pressure measurement can be completed at one instrument without repositioning the patient.
Slit-lamp biomicroscopy remains central to anterior segment diagnosis. A 2025 study in Cornea (National Library of Medicine) confirms the diagnostic value of slit-lamp imaging for evaluating anterior segment disease, underscoring the role of reliable tabletop instruments like the SL-6E in everyday eye care.
Why Practices Choose the Topcon SL-6E

- Five-step magnification — revolver-drum changer delivers 6×, 10×, 16×, 25×, and 40× for everything from broad survey to fine detail.
- Galilean binocular optics — erect, high-contrast stereoscopic image for accurate depth judgement at the cornea and lens.
- Continuously variable slit — illuminated field adjustable from 0 to 9 mm with seven aperture stops and a 1–8 mm slit length.
- Built-in filters — cobalt blue, red-free, 13% neutral density, and heat-absorbing filters support fluorescein and vascular assessment.
- Smooth joystick control — one-handed XY and vertical positioning with a height-adjustable chin rest for fast patient setup.
- Integrated Optilasa tonometer — applanation IOP measurement mounts directly to the slit lamp, no second device required.
Clinical Applications
- Routine anterior segment biomicroscopy of the cornea, conjunctiva, iris, and lens
- Fluorescein staining and dry-eye assessment using the cobalt blue filter
- Applanation tonometry for intraocular pressure and glaucoma screening
- Cataract grading and lens evaluation
- Foreign-body detection and corneal abrasion follow-up
Who This Is For
- Ophthalmology and optometry practices adding a dependable second exam lane
- New or satellite clinics seeking a complete slit lamp plus tonometer at a value price
- Teaching and screening settings needing proven Topcon optics
