The new 4MP KAE-04471 uses larger 7.4um 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. The KAE-04471 is pin and package compatible with the existing 8MP KAE-08151.
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 NIR band – an improvement that 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, VP and GM, 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.”
An intra−scene switchable gain feature samples each charge packet on a pixel−by−pixel basis, enabling the camera system to determine whether the charge will be routed through the normal gain output or the EMCCD output based on a user selectable threshold. This feature is said to enable imaging in extreme low light even when bright objects are within a dark scene, allowing a single camera to capture quality images from sunlight to starlight.
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.
