Omnivision has developed the smallest camera module for three-dimensional (3D) intraoral dental scanners using a 2MP wafer scale stacked die image sensor.

The OCH2B30 in the 3D dental scanner uses a CameraCubeChip package in an ultra-small form factor of 2.6 mm x 2.6 mm with high image quality and MIPI interface for cameras in benchtop, standalone and portable intraoral dental scanners.

“Intraoral scanners are quickly replacing the use of traditional dental impression in dentistry today. We are leveraging our proven technology from the medical endoscopy market to help advance intraoral scanners for dentistry,” said Aaron Chiang, marketing director at Omnivision.

“Our CameraCubeChip technology enables the smallest camera modules for 3D intraoral dental scanners. Similar in size to the actual CMOS image sensor inside the camera, the CameraCubeChip enables ultra-compact, high-resolution cameras, which is especially important when there are multiple cameras in each scanning device. We expect the new OCH2B30 camera module to play an important role in driving the growth of the intraoral dental scanner market and, ultimately, in improving patient care.”

The growth in 3D dental scanners is being driven by the increasing demand for cosmetic dentistry, the prevalence of dental diseases and new technological advancements in dentistry. Intraoral scanners are used primarily by orthodontists, endodontists, periodontists, prosthodontists and general dentists.

SuperResolution added to world’s smallest camera module for medical imaging

The OCH2B30 camera module has a 2MP square-format CMOS image sensor with a 1.12-micron (µm) pixel built on Omnivision’s PureCel Plus-S stacked-die technology, which enables its ultra-small size. At 1500 x 1500 resolution, the OCH2B30 achieves 60 frames per second (fps), and at 720p resolution, 120 fps.

Omnivision is ISO13485-certified for medical applications and the OCH2B30 3D dental scanner is tested for EMC/EMI compliance and sterilization, and it is biocompatible and waterproof. Because it passes a rigorous production testing, it is guaranteed to be within the stated electrical, mechanical and optimal specifications, and hence does not require tuning or calibration.

Samples of the OCH2B30 CameraCubeChip are available now.
