LN-S355 4K USB Endoscope | Multi-Specialty Clinical Examination

LN-S355 portable USB endoscope for ENT, urology, gynecology, and joint basic examination. Works with macOS, Windows, Android, and USB-in devices. 4K UHD, WDR, 8-level brightness, optical adapters, freeze frame, auto/manual white balance, IP67, carry case.

The LN-S355 is a portable USB endoscope engineered for basic clinical examination across multiple departments, including ENT, urology, gynecology, and joint/orthopedic assessment. It offers 3840×2160P 4K resolution, an imported image chip, and ultra-wide WDR, giving clinicians a detailed and balanced view for routine visual checks.

The device connects to macOS, Windows, Android, or any USB-in enabled display. Clinics can use existing computers, laptops, tablets, or panel PCs without purchasing a dedicated endoscope tower. The ultra-light ergonomic handle reduces hand fatigue during long clinics and bedside rounds, while the included carrying case supports house calls and mobile visits. The IP67-rated handle can be cleaned with alcohol wipes or low-temperature plasma sterilization.

Clinicians can adjust brightness across 8 levels, use 8× electronic zoom, and select an optional optical adapter to change focus. Freeze frame and manual/auto white balance further support clinical workflow. A 2-meter anti-interference cable with a durable jacket helps maintain stable transmission and resist breakage from repeated use.

4K Ultra-High-Definition Imaging

The LN-S355 delivers 3840×2160P 4K resolution for exceptionally clear and detailed visual examination. Fine surface structures and subtle changes are easier to observe on a compatible display.

Imported Image Chip

An imported image chip supports stable processing during multi-specialty clinical viewing. It helps maintain consistent image output across different examination sessions.

Ultra-Wide WDR

Ultra-wide WDR maximizes image quality by balancing bright and shadowed areas. This is useful when illumination varies across the examination area or when surfaces reflect light unevenly.

8-Level Brightness Adjustment

Clinicians can select from 8 brightness levels to adapt to different tissue surfaces, working distances, and ambient lighting conditions.

8× Electronic Zoom

Users can enlarge a selected area digitally without moving the scope. This supports closer visual inspection during basic examination.
