Ny generation af SWIR image-sensorer til industriudstyr

Med sigte på industriel udrustning præsenterer Sony nye SWIR (Short-Wavelength Infrared (SWIR) image-sensorer (in english).

Sony Corporation has announced the upcoming release of two new models of short-wavelength infrared (SWIR) image sensors for industrial equipment. The new sensors are capable of capturing images in the visible and invisible light spectrum in the short-wavelength infrared range and boast a compact size made possible by the industry’s smallest 5um pixel size.

The new products employ Sony’s original SenSWIR2 technology, in which photodiodes are formed on an indium gallium arsenide (InGaAs) compound semiconductor layer and are connected via Cu-Cu connection with the silicon (Si) layer which forms the readout circuit - a design which enables high-sensitivity over a broad range of wavelengths.


This breakthrough yields a SWIR image sensor that is compact yet capable of delivering seamless image capture over a broad range of wavelengths covering from the visible to invisible light spectrum in the short-wavelength infrared range (wavelength from 0.4um to 1.7um).

The recent demand to reduce manpower and ensure standardization in the industrial equipment field is driving a growing need for image sensors capable of capturing images in the invisible light spectrum of the short-wavelength infrared range.

However, traditional SWIR image sensors face manufacturing challenges in miniaturizing pixels and increasing pixel count, as well as various other issues including low sensitivity in the visible light spectrum and analog output that makes multifunctionality difficult. These factors have inhibited the penetration and increased applications of industrial cameras using conventional technology.

Sony’s new sensors employ the stacking technology using Cu-Cu connection that Sony has developed for years along with Sony’s original SWIR image sensor technology, delivering high image quality and a more compact sensor size thanks to miniaturization, as well as high sensitivity imaging in a broad range of wavelengths covering both the visible and invisible spectrum. The new products also support digital output, matching the performance of current CMOS image sensors for industrial equipment.

Going forward, Sony will propose these products for use in a wide range of industrial applications such as material selection, contaminant inspection, and semiconductor inspection, aiming to contribute to improved productivity.
