Raptor’s Ninox cooled Vis-SWIR camera helps advance medical imaging techniques

Raptor Photonics Ninox 640

An exciting new paper published by one of Raptor Photonics' customers highlights how the Ninox 640 camera has helped advance in-vivo and in-vitro medical imaging. Zbigniew Starosolski and his colleagues in Children’s Hospital, Texas have been using their cooled InGaAs Ninox camera for several months, imaging in the “NIR-II” window (1000–1700 nm) enabling deeper imaging into underlying tissues. Read the paper online here.

The availability of InGaAs cameras has propelled the development of NIR-II fluorescent dyes and imaging agents for preclinical testing based on a variety of platforms including single-walled carbon nanotubes (SWNTs), quantum dot nanoparticles, rare earth doped nanoparticles, polymeric nanoparticles, and small molecule water soluble dyes. NIR-II imaging using these agents have demonstrated improved depth of penetration, thereby enabling sub-surface vascular imaging at high spatial resolution.

The Ninox-640 is a cooled, high sensitivity digital VIS-SWIR camera. Using a 640 x 512 InGaAs sensor, the Ninox 640 enables high sensitivity imaging from 0.4µm to 1.7µm. The 15µm x 15µm pixel pitch enables highest resolution VIS-SWIR image and with less than 50 electrons readout noise the OWL 640 enables the highest VIS-SWIR detection limit. With TEC and liquid cooling to -20°C the Ninox 640 reduces dark current to ~1,500e/p/s, allowing longer exposures. Available with a 14 bit CameraLink output, the Ninox 640 will run from 10 to 120Hz enabling high-speed digital video with intelligent auto AGC.
