ams OSRAM: Providing the world's smallest digital camera module "NanEyeM" for disposable endoscopes | Motor-FanTECH.

NanEyeM offers high resolution in the smallest size that meets current market standards in the field of camera modules for digital endoscopes. In endoscopy such as bronchoscopes, the shift from reusable bronchoscopes to disposable bronchoscopes has been accelerating in recent years, but the epidemic of the new coronavirus has led to further demand for disposable bronchoscopes. It is increasing. Developed for disposable use, NanEyeM ensures a high level of sterility and reduces the possibility of secondary contamination. This is essential for critically ill patients who develop the new coronavirus. With a small size of 1.0 mm x 1.0 mm x 2.7 mm, the module can be used in a very narrow space. Dina Aguiar, Marketing Manager at ams OSRAM, said: "NanEyeM's space savings make it suitable for use in areas of severe size restrictions, including disposable applications such as bronchoscopy, urinary endoscopy, and renal endoscopy. Essential. Combined with high image quality, this camera module is a unique and attractive solution for the fast-growing disposable endoscope market. "

■ Structure of NanEyeM

This module uses the so-called "Chip-on-tip" method. Here, the image sensor and the optical system are located at the tip (distal end) of the device. This significantly improves image quality as compared to the case where the camera module is located at the other end, i.e., the proximal end. NanEyeM is a fully integrated image processing module that achieves high image quality with a wafer-level multi-element optical system. It is specially designed for optimal performance at close range. A lens that combines a wide field of view (FoV) and a wide depth of field (DOF) suppresses distortion and achieves clear and accurate images. The camera uses a digital LVDS (Low Voltage Differential Signaling) serial interface to provide a high signal-to-noise ratio (SNR). This allows the camera to transmit over long cables without compromising signal integrity or increasing noise. In addition, NanEye M boasts a frame rate of up to 49fps (frames per second), enabling smooth, low-latency display over a wide range of standard interfaces while maintaining low power consumption. The image sensor requires less illumination due to the high-sensitivity pixels. As a result, heat generation at the tip of the device is suppressed. This module comes with a cable that can be customized up to a length of 3m according to customer requirements. By using this attached cable, smooth and seamless integration into endoscopic equipment can be ensured. It is also possible to add an LED light source to the tip.

■ NanEyeM saves space and cost

NanEyeM's fully digital output eliminates the cost of an external ADC because the analog-to-digital conversion (ADC) is done on the chip. This module is less susceptible to magnetic interference (EMI / EMC) from medical devices in the surgical environment, eliminating the need for coaxial or shielded cables. Since the cable is connected in advance, additional acquisition cost can be avoided and the manufacturing cost of the endoscope can be reduced. Using NanEyeM for disposable endoscopes not only makes it very hygienic, but also reduces the cost of maintenance, reprocessing and repair of reusable endoscopes that are common in everyday clinical practice. can. Moreover, it does not need to be sterilized before the next use, so it can be used at any time. This module is designed for mass production to ensure cost competitiveness and supply capacity. NanEyeM is the second generation of NanEye2D from ams OSRAM. This camera module is in production and is accepting orders.
