NIR imaging with this versatile InGaAs camera

The Alizé 1.7 is a SWIR scientific grade camera, with an InGaAs detector that combines performance with reliability. It has low noise levels, high efficiency, and a rapid frame rate compatible with an external trigger. This is made possible by combining our state-of-the-art control electronics and a four-stage thermoelectric cooler (TEC). While maintaining an operating temperature as low as -50 °C, the TEC uses forced air cooling that alleviates the need for a water or liquid nitrogen chiller unit.

The Alizé 1.7 is among the most cost-effective sensitive SWIR InGaAs cameras on the market.

Alizé 1.7 Applications Overview

  • NIR-II/SWIR Bio-imaging

  • Photovoltaics characterization by photoluminescence (PL) and electroluminescence (EL) using SWIR imaging

  • Semiconductor wafers inspection and device failure detection

  • Laser beam profiling

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


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…
