Sony Semiconductor Solutions Corporation has launched the new IMX487 with the UV (ultraviolet light) wavelength and the industry’s highest effective pixel count of approximately 8.13 megapixels.
The IMX487 is a 2/3-type CMOS image sensor with global shutter functionality which delivers a high level of UV sensitivity and high-quality imaging with minimal noise thanks to components specialized for the UV wavelength and a unique light receiving unit structure.
Additionally, the pixels capture UV light with high efficiency, resulting in high UV sensitivity as well as a compact form factor and high resolution made possible by the industry’s smallest 2.74 µm square pixel size.
It utilizes Sony´s Pregius S global shutter technology, which employs a unique back-illuminated pixel structure on a stacked CMOS image sensor, ensuring distortion-free imaging and high-speed performance.
The new IMX487 sensor delivers high-speed performance at 193 fps (in 10-bit mode) and supports SLVS / SLVS-EC output interfaces.
It is compatible with the 200 to 400 nm wavelength, which is the most suitable UV wavelength for industrial inspections.
In addition to conventional UV image sensor applications such as semiconductor pattern defect inspection, the IMX487 can be used to solve a variety of industrial challenges, including sorting plastics and other materials using UV light at recycling plants, inspecting for the application of transparent resin, inspecting for minute scratches on the surface of components, and detecting UV light emitted due to discharges in deteriorating overhead power lines.
Samples of IMX487 UV Wavelength-Compatible CMOS Image Sensor are available by FRAMOS as of October 2021.
