California-based OmniVision, a well-known developer of image sensors, said that one of its latest developments, the OV6948 sensor, is included in the Guinness World Record as the smallest commercially available image sensor in the world. Derived from this ultra-small imager, the company also announced its OVM6948 CameraCubeChip, a fully packaged, wafer-level camera module measuring 0.65 mm x 0.65 mm, with a z-height of just 1.158 mm.
This record is not surprising given the dimensions of the OmniVision OV6948 – 0.575 mm long and 0.575 mm wide, for 0.232 mm high. In other words, its size is smaller than that of a grain of rice! With its help, you can get an image of 200 x 200 or 40 thousand pixels with a size of 1.75 microns. The viewing angle of the lens is 120°.
OmniVision OV6948 captures video at 30 frames per second, and its analog output can transmit over 4 meters with minimal noise. The camera consumption is no more than 25 mW. The OmniVision camera can withstand temperatures ranging from -20° C to +70° C.
Its resolution may seem low, but it was not created for professional filming. It is designed to help doctors in medical examinations. With such a camera, the diameter of the endoscope will not exceed 1 mm, which will allow you to visually examine even small blood vessels in the patient’s body. Traditional endoscopes are too large and can cause discomfort during medical procedures, and also not always effective.
