The Firefly S390L Digital Slit Lamp

The Firefly S390L is a fully integrated digital slit lamp with a built-in 12-megapixel camera and MediView imaging software — designed to turn everyday anterior segment exams into documented, shareable clinical conversations. High sensitivity imaging keeps the slit sharp and clear under weak light, while wide dynamic range captures iris and sclera simultaneously with realistic color distribution. The Firefly also supports infrared meibomian gland evaluation with AI-assisted gland loss analysis and orthokeratology lens fitting documentation. The system connects via USB to your existing exam lane CPU (or any Windows PC), so there’s no dedicated workstation to plan around. For practices that want integrated slit lamp documentation and cleaner anterior segment imaging without bolting on aftermarket adapters.

Practice Fit

Where The Firefly Wins

If your practice wants to document every slit lamp finding with integrated digital imaging — not a bolted-on aftermarket camera adapter — The Firefly is the platform.

Best Fit

Comprehensive ophthalmology, medical optometry, anterior segment, and MGD focused practices that want to document every slit lamp finding with integrated digital imaging — not a bolted-on aftermarket camera adapter.

Why This

The Firefly’s 12-megapixel camera is engineered into the optical path with automatic exposure and wide dynamic range. Infrared meibography with AI gland analysis and ortho-k lens fitting capture give you documentation capabilities that bolt-on solutions cannot match.

Practice Impact

Strengthens patient education with side-by-side image comparisons, supports meibomian gland evaluation with objective infrared evidence, and turns routine anterior segment findings into visual conversations that improve treatment acceptance.

Platform Strengths

Why Practices Choose The Firefly

Integrated 12 MP Digital Imaging

The camera is built into the optical path — not adapted or bolted on. Every slit lamp exam becomes an imaging opportunity with automatic exposure, gain, and white balance, plus 30fps video capture for real-time documentation.

Infrared Meibography

Infrared meibography with AI-assisted gland loss analysis identifies meibomian gland changes and anchors MGD conversations with objective imaging evidence your patients can see.

Plug-and-Play Integration

Connects via USB to your existing exam lane CPU or any Windows PC running MediView. No dedicated workstation to plan around, no new footprint in the lane — just add imaging to the computer you already have.
