LN-S355 4K USB Endoscope for Mobile & Bedside Examination

LN-S355 portable USB endoscope for mobile clinics and bedside examination. Works with macOS, Windows, Android, and USB-in devices. 4K UHD, WDR, 8-level brightness, optical adapters, freeze frame, IP67, carry case.

The LN-S355 is a mobile-ready USB endoscope built for clinicians who examine patients outside standard consultation rooms. It fits house calls, bedside reviews, mobile clinics, and temporary care points. The scope connects to macOS, Windows, Android, or any USB-in display, so doctors can use a laptop, tablet, or existing screen instead of transporting a fixed workstation.

Its lightweight ergonomic handle is shaped for prolonged hand-held use. The included carrying case keeps the scope, cable, and accessories together during travel. The handle is IP67 sealed and can be wiped with alcohol or processed with low-temperature plasma sterilization.

The LN-S355 delivers 3840×2160P 4K imaging through an imported chip. Ultra-wide WDR helps manage difficult lighting, while 8-level brightness adjustment, 8× electronic zoom, optional optical adapters, freeze frame, and manual/auto white balance give clinicians practical control during bedside and mobile examination. A 2-meter anti-interference cable with a durable jacket supports stable transmission and long service life. No additional software is required — simply connect to a computer and start viewing.

Mobile-First Connection

The LN-S355 can send video to macOS, Windows, Android, and USB-in enabled screens. Clinicians can use a laptop or tablet already available on site.

Clear 4K Image

3840×2160P 4K output gives a highly detailed view for basic examination. Fine visual details are easier to observe on a compatible display.

Stable Imported Chip

An imported image chip supports consistent processing during mobile sessions, helping maintain reliable visual feedback.

WDR for Variable Lighting

Ultra-wide WDR helps balance bright and dark areas. It is useful in homes, wards, and temporary clinics where lighting may change.

8-Level Brightness Control

Users can choose from 8 brightness levels to match different examination surfaces and ambient light conditions.

8× Electronic Zoom

Users can enlarge a selected area digitally without moving the scope. This supports closer inspection during bedside review.

Optional Optical Adapters

The LN-S355 supports optional optical adapters for focus adjustment. Available mount sizes are F20MM, F22MM, F25MM, F28MM, and F14-35MM. These help clinicians adapt to different working distances.
