Abstract

SiOnyx has demonstrated imaging at light levels below 1 mLux at 60 FPS with a SXGA backside illuminated CMOS image sensor in a compact, low latency camera. Sub mLux imaging is enabled by the combination of enhanced quantum efficiency in the near infrared, backside illumination for 100% fill factor, and state of the art read noise of 1.1 e/pix. The quantum efficiency enhancement is achieved by utilizing SiOnyx’s proprietary nano and microtexturing processing technology in a backside illuminated architecture for high fill factor and enhanced near infrared absorption. The sensors can be configured with Bayer color filters for color imaging below quarter moon.
