Lowest Read-Out Noise SWIR Camera Released
The camera is the culmination of work done by Lytid, NIT and the French Research Agency (CNRS).
Lytid has released the SIRIS (Short-wave InfraRed Imaging System) SWIR camera – a deep cooled SWIR camera based upon a Lin/Log InGaAs sensor from NIT and image processing algorithms from the French Research Agency.
The company says SIRIS exhibits the best performance on the market for read-out noise (<10e-) and dynamic range (>120dB) simultaneously, in part thanks to the NIT Lin/Log 1601 SWIR sensor. SIRIS is deep cooled down to 50K with a long-life cryocooler allowing a reduction of dark current. Everything is fully integrated into a compact and plug-and-play casing based on Lytid’s advanced photonic system integration. The camera is ready to be used in a few minutes thanks to the closed-cycle, cryogenic–free cooler.
SIRIS provides two read-out modes, full linear and linear/logarithmic, that combines with nondestructive read-out (NDRO) and allows for class-leading dynamic range. Three adjustable gain levels ensure flexibility to suit a broad variety of illumination conditions. Long exposure time up to one hour is achievable, and selectable region-of-interest on the detector allows “exceptional frame rate values”.
SIRIS incorporates advanced noise reduction algorithms developed by ENS-CNRS, among which non-destructive read-out noise reduction is embedded. The resulting noise performance is drastically reduced and the final readout noise is less than 10e-.
Thanks to its high-edge performances, the company says SIRIS is the perfect tool for ambitious scientific applications, such as astrophysical observations, hyperspectral and biological imaging, spectroscopy and semiconductor failure detection.
Lytid is a French company developing, manufacturing and commercializing terahertz technologies for scientific and industrial applications via their two core technologies: the Quantum Cascade Laser (QCL) and Schottky diode multipliers.
Lytid’s first product, TeraCascade, a compact and powerful terahertz QCL source, was awarded the Prism Award for Photonics Innovation in the category “Scientific Lasers” at Photonics West 2016. More recently, they aim to be involved with the mobilisation of the French National Research Agency for COVID-19 research, which will include 234 research projects funded for a total amount of 32.2 million euros.
