The KAI-04022 Image Sensor builds on the capabilities of the popular KODAK KAI-4021 Image Sensor by adding a new low-noise amplifier that reduces sensor read noise by 25%. With this improvement, scientists working in applications such as fluorescence microscopy can more successfully detect and measure low-light signals, enabling more accurate and detailed analysis of their samples.

“Scientists working in low-light applications have a never-ending need for improved performance from their detection systems,“ said Chris McNiffe, General Manager of Kodak’s Image Sensor Solutions group. “With this new sensor, scientific customers now have access to new low-light imaging regimes, without sacrificing the high resolution and fast frame rate that are critical for accurate imaging in these applications. This new product shows Kodak’s continued commitment to develop and commercialize image sensors that meet and exceed the needs of our customers.“

The KAI-04022 image sensor expands Kodak’s extensive portfolio of interline transfer CCDs which are designed for a variety of applied imaging markets. With a 2048 x 2048 array of 7.4 micron pixels, dual outputs to enable up to 15 frames per second readout speed, and fast line dump to facilitate region-of-interest (ROI) imaging, the KAI-04022 shares key design and performance features of the existing KAI-4021 image sensor. By incorporating a new high sensitivity output amplifier, however, the read noise of the KAI-04022 has been reduced by 25% compared to the current KAI-4021, enabling new uses for low-light imaging while simultaneously expanding the dynamic range of the new sensor. To facilitate adoption of the new part, the KAI-04022 shares the same package and pin-out configuration as the current KAI-4021, allowing existing designs to be easily modified to make use of the new part.

Engineering samples of the KAI-04022 image sensor are now available, with volume production planned for early 2008. For customers that do not require the new low-noise features of the KAI-04022, the KAI-4021 image sensor remains available.-Kodak
