NIT is pleased to introduce its latest member of the popular SWIR WiDy SenS family. The WiDy SenS 640H-STE was designed for UAV gimbal and PZT manufacturers who want to integrate a SWIR channel in their systems. 

The WiDy SenS 640H-STE provides straightforward interfacing with the most current electronic video platforms. WiDy SenS 640H-STE has a digital video SDI output directly compatible with processing units such as NVidia, Texas Instruments, ARM processors or Analog devices, and many others. This camera integrates the NSC1601 SWIR VGA sensor that offers a high dynamic range of more than 120dB and high sensitivity with low noise, making the camera ideal for airborne fire fighting, search and rescue, and agricultural mapping.  

The control and command of the camera can be programmed through our SDKs, available for Windows and Linux or more simply from our NITVision software suite.

In addition, WiDy SenS with SDI interface has a small form factor that facilitates its mechanical integration and also exhibits a very low power consumption of less than 5W that makes it ideal for battery-powered devices. 

Lisa SWIR – The Ultimate Tool for Electronic Components, Silicon Wafers, and Solar Panels Inspection.

Lisa SWIR is a line scan SWIR camera using the NSC1801 SWIR sensor developed by NIT which has 2048 pixels, with a pixel size of 7.5um x 7.5um. The line repetition rate is fully programmable and can go up to 60KHz, the digital output being 14bits with Camlink format. The camera can be triggered through an external signal coming from the conveyor and will provide an extremely precise timing definition of the image acquired.
Lisa SWIR was specially developed for semiconductor inspection, with the ability of SWIR wavelength to see through silicon.  Inspection of silicon wafers or of single dies can be easily set up.
The solar panel both at production and on-site can be inspected by Lisa SWIR providing extremely accurate images of photoluminescence induced by small defects even at low contrast.

Thanks to its small pixel size of 7.5um, Lisa SWIR procures extremely sharp and crisp images of defects in materials at high throughput. The small size of each pixel of 7.5um compared to larger competing arrays with 12um pixel size or more is a major breakthrough in reducing production costs. Moreover, the smaller pixel size induces a smaller array size, which in turn allows using smaller optics for the same field of view.

The SWIR sensors are manufactured at the NIT factory using an innovative bonding process that guarantees the lowest achievable number of defects in the line.

Together with its partner in Singapore (vitalvisiontechnology.com) NIT and VITAL Vision can offer a complete solution for semiconductor inspection, that includes a high homogeneity illumination system and real-time inspection software

NIT is a French company specializing in the design and production of SWIR InGaAs sensors, both 2D arrays or linear arrays. NIT is vertically integrated and produces sensors, cameras, and software.

Vital Vision Technology is the leader in Machine Vision Components and Technologies in Southeast Asia, providing companies with cutting-edge vision solutions to price-sensitive vision solutions.

NIT expands its SWIR camera portfolio with the latest SenS 1280S-VT model which integrates NIT 1280x1024pixel @ 10um sensor. The camera operates with a USB3 output and is bundled with GUI – NITVISION software and SDK for major operating systems.

Sens1280V-ST exhibits outstanding world-class performances such as :

• Readout noise of typ. 27e-
• QE > 85%
• Frame rate > 60Hz at full frame
• Programmable Regions of Interest
• 14bits Digital output

Applications include laser beam analysis, silicon, and solar wafer inspection, process control, medical, food analysis, microscopy, etc.

Sens1280V-ST is the first of the long list of HD cameras to be released in 2021, the next available one will be a Camlink version due in July.

Together with the high-performance air-cooled camera series – HiPe SenS, released last year, the SenS series propose more resolution options to clients in Linear response: VGA (640x512px) and SXGA (1280x1024px).

New Imaging Technologies (NIT) thanks the French Government for their support with the “France Relance” Program in developing the industrialization of our novel in-house stacking technology, recognizing NIT’s breakthrough R&D process development in SWIR sensor production. NIT will be able to address volume production and high-resolution SWIR sensors with this industrialization process

Abstract

Nanocrystals are semiconductor nanoparticles whose optical properties can be tuned from UV up to THz. They are used as sources of green and red light for displays, and also show exhibit promises to design low-cost infrared detectors. Coupling subwavelength optical resonators to nanocrystals film enables to design photodiodes that absorb 80% of incident light from thin (<150 nm) nanocrystal film. It thus becomes possible to overcome the constraints linked to the short diffusion lengths which result from transport by hopping within arrays of nanocrystals enabling a high photoresponse detector operating in the SWIR range

NIT is pleased to announce the sampling and production of its latest high definition SWIR image sensor

NSC1901T-SI is the latest generation of NIT SWIR sensor having a pixel resolution of 1280×1024 pixels at a pitch of 10um, with the extraordinary low readout noise performance of typically 25e-, thanks to its innovative input stage and in pixel CDS.

NSC1901T-SI delivers up to 120 frames per second, operates in IWR and ITR mode, and can be combined with ROI readout. This first member of the SXGA family has a linear response only. The dual-mode Linear and Logarithmic response will be available in Q3-2021.

NSC1901T-SI is manufactured using the advanced NH process developed by NIT. This in-house technology allows the production of hybrid components without using the traditional Indium bump technique leading to high yield manufacturing.

NSC1901T-SI will be integrated first into the NIT SenS camera line – the SenS 1280 camera is due to be out in May 2021.
