Kowa SL-15 — Used Portable Halogen Slit Lamp with Carrying Case

The SL-15 delivers halogen illumination with continuously variable slit width up to 14 mm, two-step magnification (10× and 16×), and a built-in cobalt blue filter — replicating the core anterior-segment workflow of a benchtop slit lamp in a handheld format. Battery operation makes it the right choice for hospital bedside rounds, ER consults, nursing-home visits, low-vision evaluations, and pediatric exams where the patient cannot come to a chair.
According to a National Library of Medicine-indexed study (Indian J Ophthalmol, 2026), portable slit-lamp imaging produces clinically useful anterior-segment photographs comparable to conventional benchtop biomicroscopes — supporting the workflow the Kowa SL-15 was designed to deliver.
Why Practices Choose the Kowa SL-15
Fully portable handheld design — examine patients at the bedside, in the ER, or on home visits where a benchtop slit lamp can’t go.
- Halogen illumination — bright, color-accurate light source with the warm color temperature traditional clinicians prefer for cornea and lens evaluation.
- Two-step magnification (10× / 16×) — covers routine biomicroscopy ranges in handheld format.
- Continuously variable slit width up to 14 mm — full clinical range despite the compact form factor.
- Built-in cobalt blue filter — fluorescein imaging without filter accessories.
- Battery operation — no AC tether required during exam; ideal for hospital rounds and outreach clinics.
- Carrying case included — protects optics during transport (non-original substitute case, as photographed).
- Kowa reliability — same Japanese manufacturer behind Kowa fundus cameras and the Kowa SL-17; familiar brand with global service support.
Clinical Applications
- Bedside ophthalmology consults — anterior-segment exam in hospital rooms, ICU, ER.
- Home-visit eye care — slit-lamp biomicroscopy for homebound patients.
- Nursing home / assisted living rounds — exam without transferring patients to a chair.
- Pediatric exams — bring the slit lamp to the child instead of the reverse.
- Low-vision evaluation — patient comfort during the exam improves cooperation.
- Mobile / outreach clinics — fully portable exam capability for tele-ophthalmology workflows.
Who This Is For
- Hospital-based ophthalmologists who need a portable slit lamp for inpatient consults.
- Home-care, nursing home, or mobile-clinic providers serving patients who can’t come to the chair.
- ER ophthalmology coverage — quick anterior-segment exam without moving the patient.
- Pediatric and low-vision practices where patient mobility is limited.
- Veterinary ophthalmologists who frequently work outside a standard exam lane.
