As manufacturers in various industries continue to seek higher productivity, there is growing interest in sensing both in the visible spectrum and beyond it, at SWIR wavelengths.
In IMX990 and IMX991, SenSWIR technology has enabled Sony to overcome challenges in pixel miniaturization to offer sensors that are compact, high-resolution, and capable of imaging from the visible spectrum to SWIR wavelengths. IMX990 and IMX991 are global shutter sensors with a digital output allowing for many features and functionality in industrial camera applications such as ROI and Trigger Mode
The advances in performance and functionality introduced by the IMX990 and IMX991 pave the way for the development of SWIR industrial cameras and inspection equipment for a diverse range of applications such as inspection, identification, and measurement.
Advantages of the sensors promise to expand SWIR sensing applications. The sensors' higher resolution offers higher inspection precision, and smaller cameras afford greater freedom in installation.
Inspection that once required multiple cameras to cover visible and SWIR wavelengths can now be performed with a single unit. Such broad coverage expands both the type of objects that can be inspected and the type of inspection available. System costs can be reduced, and faster image processing can increase throughput.
Unlike the analog output that most SWIR sensors are limited to, the sensors also feature digital output, for performance on the level of current industrial CMOS sensors. Analog sensors require developers to implement an ADC or other functionality for industrial equipment on the camera. In contrast, the new sensors already include this functionality, which saves time and effort in camera development and makes it easier to develop versatile cameras.
