Ultraviolet (UV) Image Sensor

Overview

In a wide range of industrial applications, utilization of image sensors exceeding human eyes are becoming more popular recently. One such example is the sensing of UV/ultraviolet wavelengths, outside the spectrum of visible light.

IMX487 is an image sensor with UV imaging capability while its Pregius S™ technology facilitates the global shutter function and high speed operation. It is adaptable to a wide range of use cases such as, apart from the typical semiconductor pattern inspection, material sorting at a recycling plant, inspection of micro-defects on product surfaces, and infrastructure inspections as well as in life science.

Features

Equipped with global shutter capable of high-speed and undistorted photography

With the structure specially designed for the properties of the UV wavelengths coupled with Pregius S technology, the image sensor can capture undistorted images of moving objects within a UV range of 200–400 nm and at a high frame rate of 193 fps (operated in the 10-bit mode). This image sensor has a potential to expand the scope of application from the conventional use of UV cameras in the inspection of semiconductors, etc. to areas that require high-speed capability, such as sorting of recycled materials.

Achieving high-resolution and low-noise photography

This image sensor has adopted the component materials dedicated for UV range imaging, and a special structure has been developed for its light receiving area. These make it possible to maintain high UV sensitivity while significantly minimizing noises to produce high quality images.

Huge number of pixels to cover versatile applications

The pixels are miniaturized down to 2.74 um while maintaining high UV sensitivity, realizing a small multi-pixel sensor of the 2/3 type with approximately 8.13 megapixels. It serves well with factory automation, but also for many other purposes, notably for outdoor use for infrastructure inspections, by virtue of its portability and high resolution.

What is UV?

The diagram below is a simplified illustration of the light spectrum. Ultraviolet (UV) has shorter wavelengths than visible light, typically ranging between 10–400 nm. IMX487 covers the range between 200–400 nm, which is the UV range suitable for industrial applications.
