ON Semiconductor announced new CCD image sensors which double the light gathering capability and improve image quality for low-light industrial applications such as medical and scientific imaging, as well as commercial and military applications for high-end surveillance.
The new 4 megapixel KAE-04471, part of the Interline Transfer EMCCD devices, uses larger 7.4 micron pixels than those found in existing IT EMCCD devices, doubling the light gathering capability of the new device and improving image quality under light starved conditions.
Camera manufacturers can upgrade the existing camera designs using the previous 8 megapixel KAE 08151 with the new KAE-04471 as both the devices are pin and package compatible.
The new KAE-02152 shares the same 1080p resolution and 2/3” optical format as the existing KAE 02150 , but incorporates an enhanced pixel design that increases sensitivity in near-infrared (NIR) wavelengths. This improvement, ON Semi says, can be critical in applications such as surveillance, microscopy, and ophthalmology.
The KAE-02152 is fully drop-in compatible with the existing KAE-02150, and both devices are available in packages that incorporate an integrated thermoelectric cooler, simplifying the work required by camera manufacturers to develop a cooled camera design.
“As the need for sub-lux imaging solutions expands in surveillance, medical, scientific, and defense markets, customers are looking for new options that provide the critical performance required in these applications,” said Herb Erhardt, Vice President and General Manager, Industrial Solutions Division, Image Sensor Group at ON Semiconductor. “The new products allow customers to choose from a variety of resolutions, pixel sizes, sensitivities, color configurations, and packaging options in our IT-EMCCD portfolio to meet their low-light imaging needs.”
As stated in the announcement, “while Interline Transfer CCDs provide excellent image quality and uniformity with a highly efficient electronic shutter, this technology is not always ideal for very low-light imaging. And while EMCCD image sensors excel under low-light conditions, they historically have only been available as low resolution devices with limited dynamic range.”
The firm noted that combining these technologies allows the low-noise architecture of EMCCD to be extended to multi-megapixel resolutions, and an innovative output design allows both standard CCD (normal-gain) and EMCCD (high-gain) outputs to be utilized for a single image capture – extending dynamic range and scene detection from sunlight to starlight in a single image.
Engineering grade versions of the KAE-04471 are now available, with production versions available in 2Q17.
Engineering grade versions of the KAE-02152 in both a standard package as well as a package incorporating an integrated thermoelectric cooler are also available, with production versions of both configurations available in 3Q17.
All IT EMCCD devices ship in ceramic micro-PGA packages, and are available in both Monochrome and Bayer Color configurations.
Evaluation kits for devices in the IT-EMCCD portfolio are available for purchase. For more details, view the full Press release.
