The OV6948 from OmniVision Technologies is the Smallest (size of 0.575 x 0.575 x 0.232 mm) Commercial CMOS Image Sensor for Medical Applications. Initially developed for small-outer-diameter medical endoscopes and catheters, the OV6948 can be designed into a wide range of applications, including dental, veterinary, internet-of-things (IoT), industrial, wearable and forensic devices. It has a 1/36-inch optical format and an image array capable of capturing 200 x 200 resolution video at up to 30 frames per second (fps). The image sensor offers exceptional low-light sensitivity of 1000 mV/lux-sec, and using OmniVision's proprietary sensor technology, delivers excellent image quality in terms of color fidelity, sharpness, and low noise.
Due to the sensor's low power consumption, less heat is generated at the distal tip of the endoscope, improving patient comfort and thus permitting longer-duration procedures. The sensor enables easy integration, with a 4-pin interface and analog data output, capable of data transmission of up to 4 meters with minimal signal noise.
