The Alizé 1.7 from Photon etc. is a high-end, scientific-grade InGaAs camera with a pixel resolution of 640 x 512. The camera integrates performance with reliability and features high efficiency, low noise levels and a quick frame rate that is compatible with an external trigger.
This can be achieved by a combination of the latest control electronics and a four-stage thermoelectric cooler (TEC) that can hold operating temperatures as low as −50 °C. In return, the TEC makes use of forced air cooling, which needs absolutely no maintenance compared to a water-cooled or liquid nitrogen-cooled unit.
The Alizé 1.7 is among the most affordable high-end InGaAs cameras that are commercially available.
Key Features
- Measures around 0.45 to 1.7 µm
- InGaAs FPA
- Low noise level
- Four-stage thermoelectric cooling
- Most affordable high-end NIR-SWIR camera
Applications Overview
- Pharmacology: In vivo NIR-II monitoring pharmacokinetics and biodistribution in real-time improves and replaces present methods utilized in the NIR-I and visible wavelengths.
- Physiology: Users can study the physiological activity in vivo like the nervous system, the endocrine system, the gastrointestinal motility and digestive system, the heart blood circulation, the oxygen delivery to using matching, the water and salt balance, etc.
- Clinical: Perfect for image-guided surgery as working in NIR-II than NIR-I offers higher tumor-detection sensitivity. It has a higher tumor-to-normal-tissue signal ratio and also an improved tumor-detection rate.
- Remote sensing: Aerial imagery offers foundational context and visualization of ground conditions. This empowers organizations to make crucial and time-sensitive decisions.
- Process monitoring and inline sorting: Classifying systems for plastic versus biocomposite or paper versus cardboard help enhance the quality of the secondary material.
- Mining and geology: It help geologists spend less time logging data and more on interpretation while enhancing quality, consistency and timeliness of geological data captured.
- Agribusiness: Enhance soil or food quality by examining the contaminants present in soils, the sugar or water content of fruits or fat and protein levels in liquid.
Cooling Swir Sensors: An Overview
Dark current is considered to be a crucial parameter while trying to find ways to obtain a scientific imaging camera, particularly in the short-wave infrared (SWIR) region.
Great attention must be given to the cooling method utilized to improve this parameter. It comes with multiple cooling technologies, each having a few benefits and drawbacks. In its ZephIR and Alizé line of SWIR cameras, Photon etc. utilizes a four-stage thermoelectric (TE4) air-cooled system to improve the sensitivity of its imaging sensors.
