Deeply Cooled InGaAs Camera

The ZephIR 1.7 is a high-end, scientific grade, 640 x 512 pixels resolution, InGaAs camera that marries performance with reliability. It has extremely low noise levels, high efficiency, and a rapid frame rate compatible with an external trigger. This is made possible by a combination of state-of-the-art control electronics and a four stage thermoelectric cooler (TEC) which can maintain an operating temperature as low as -80 °C. The TEC, in turn, uses forced air cooling which requires none of the maintenance of a water or liquid nitrogen chilled unit.

The ZephIR 1.7 is one of the most sensitive and dependable InGaAs cameras on the market.

When Art, Science and Technology Work Hand in Hand

Photon etc. presents this short film shot in collaboration with Dr. Daniel Heller, researcher at the Memorial Sloan Kettering Cancer Center and Joseph Cohen, multidisciplinary artist. This short video documents how three experts in their respective fields benefit from and are enhanced by their mutual collaboration. Joseph creates new paint mixtures and textures using carbon nanotubes (CNT). Dr. Heller develops infrared probes and biomarkers using CNT’s. Sébastien (CEO at Photon etc.) develops science grade infrared cameras that can detect fluorescent CNT’s excited by specific wavelengths.

In Vivo NIR-II Imaging: Contact-Free Monitoring Heartbeat & Respiratory Rate

High-speed imaging made available by the fast frame rates of InGaAs cameras allows for contact-free cardiography and respiratory rate measurements in both anesthetized and awake animals. Such contact-free measurements of awake mice obtained without the use of any restraining device could drastically change studies procedures in labs.

Real-Time Biodistribution and Pharmacokinetics of ICG in a Mouse Using NIR-II Fluorescence

Video of IR VIVO imaging experiment showing the biodistribution and pharmacokinetics of ICG in real time. IR VIVO is able to visualize NIR probes at high resolutions. From one single injection, it was possible to obtain measurements of heartbeats, respiration and intestinal contraction rates.

In Vivo NIR-II Imaging of Liver Metabolism, Hepatobiliary Elimination & Gastro-Intestinal Motility

With a simple tail-vein injection of ICG, we can study liver metabolism, measure hepatobiliary elimination and monitor gastrointestinal motility simultaneously in vivo and contact-free. Such a straightforward method to image the intestine could help research on metabolic diseases.

Cooling Swir Sensors: an Overview

Authors Simon Lessard and Laura-Isabelle Dion-Bertrand

Abstract

Dark current is a critical parameter when one is looking to acquire a scientific imaging camera, especially in the short-wave infrared (SWIR) region. Very careful attention must be paid to the cooling method used to optimize this parameter. Multiple cooling technologies are available, each having certain benefits and drawbacks. In its ZephIR and Alizé line of SWIR cameras, Photon etc. uses a…

In Vivo NIR-II Imaging: A Disruptive Force for Preclinical Research

Authors Stephen Marchant, Jacob Yvon-Leroux and Émilie Beaulieu Ouellet

Abstract

In vivo imaging in the second near-infrared biological window (NIR-II) is in its early stages but will undoubtedly affect life science research on many levels. The NIR-II (short-wave infrared, or SWIR) imaging modality is not affected by drawbacks of light propagation in living tissues in the same way that other techniques are. Thus, it enables much deeper real-time imaging of optical probes in…
