OmniVision is introducing the world’s first RGB-IR medical image sensor – OH02A1S! It provides simultaneous white-light RGB captures and infrared monochrome captures in a single CMOS sensor. While endoscopic precancer and cancer detection procedures are performed using IR light, surgeons also need RGB light to confirm any abnormalities detected using infrared. Previously, this could only be accomplished by integrating two independent imager sensors, which resulted in endoscopes with a larger size, higher cost and higher power consumption, thereby excessively heating the tip of the endoscope.
The new OH02A1S enables the designers of chip-on-tip endoscopes for cancer detection to eliminate a second image sensor, thereby overcoming the drawbacks of a two imager design. These improvements allow the development of small outer diameter (OD) endoscopes for cancer detection and diagnosis procedures such as indocyanine green (ICG), and fluorescence, chromo and virtual endoscopy.
“Until now, the need for two image sensors made the size and heat of endoscopes excessive for many areas of the body. Additionally, the added cost was too high for disposable scopes.”
- 1.4 micron PureCel® pixel architecture offers high quantum efficiency for excellent low-light performance
- 4×4 binning for the highest image quality
- Consumes just 90 milliwatts at full power, generating less heat for greater patient comfort
The OH02A1S image sensor is available today in an RW package and the chip-scale package will be available based on project demand.
