Anitoa Ultra-low Light Bio-optical Sensor in Volume Production

PRNewswire: Anitoa, a Menlo Park CA startup since 2012, announces the volume production of its Ultra-low-light CMOS bio-optical sensor, ULS24. Capable of 3x10-6 lux low-light detection, Anitoa ULS24 is said to be "the world's most sensitive image sensor manufactured with proven low-cost CMOS image sensor (CIS) process technology."

Until now, molecular testing such as DNA or RNA, and immunoassay testing (e.g. ELISA) rely on traditional bulky and expensive Photon Multiplier Tube (PMT) or cooled CCD technologies. "Following the trend of CMOS image sensors replacing CCDs in consumer cameras, many customers are exploring this CMOS Bio-optical sensor to replace CCD or PMT designs for new products," says Anitoa SVP Yuping Chung. With Anitoa ULS24 now in volume production, it's low-light sensitivity is said to rival PMTs and CCDs used in molecular and immunoassay testing devices. ULS24 achieves this high level of sensitivity through the innovation of temperature compensated dark current management algorithm.


  1. Is this a single point detector or imaging array?

    1. I've added the data from the company's product brief. It has 24 x 24 pixel resolution.
