The 4Klear Camera & Recorder

A TRUE Native 4K All-In-One Medical Camera and Recorder Solution

This product has been retired

The 4Klear is a Medical Grade Native 4K Camera & Recorder 2 in 1 solution designed for surgical microscopes. The remote camera head offers a large ½” Native 4K CMOS chip designed to better duplicate the surgeon’s field of view (FOV) seen in the microscope. Produce live 4K video, record 4K video, control camera settings and manage entire patient workflow via an easy to use 12.7cm multi-touch screen.

BT2020 Color Gamut
10bit 4:2:2 color @60Hz

First to market as a c-mount Medical Grade Microscope native 4K camera with a wide BT2020 Color Gamut, 12G-SDI output and 4K recording capability.

BT2020 – 10bit 4:2:2 live video produces the best possible color representation to the human eye which allows for near perfect duplication of the optical pathway of a surgical microscope. 

The state-of-the-art ½” back-illuminated 4K CMOS chip produces more light per pixel for light sensitive operations and reduces noise in the video all designed to give the surgeon and staff critical clarity for the surgical environment.
