The next-generation OH08A and OH08B complementary metal-oxide-semiconductor image sensors ― the first 8 megapixel (MP) resolution sensors for single-use and reusable endoscopes ― have been launched by OmniVision Technologies Inc.
The medical-grade OH08A image sensor features a 1/2.5 inch optical format, incorporates 1.4 µm PureCel Plus-S pixel technology and offers 4K2 K resolution in a small 7.1 mm x 4.6 mm package, which is ideal for chip-on-tip endoscopes. The OH08B has a 1/1.8 inch optical format, uses a larger 2.0 µm PureCel pixel in a 8.9 mm x 6.3 mm package and features OmniVision’s Nyxel technology, which allows enhanced visualization in the near-infrared spectral range.
Other key features include a 15.5° chief ray angle (CRA) for the OH08A and 11° CRA for the OH08B, enabling the use of lenses with large field of view and short focus distance; pulse width modulation output LED drivers; and four lane MIPI output with raw data. These sensors are stereo ready with frame synchronization to support a host of depth perception applications. Additionally, they are autoclavable for reusable endoscope sterilization.
