New tiny sensors for medical markets

13th November 2018


ams has announced the introduction of the latest products in its NanEye family. The NanEyeM and NanEyeXS will enable the production of high-performance, single-use endoscopes for use in minimally invasive surgery.

The new 1mm2 NanEyeM offers a high-resolution 100kpixel readout over an LVDS digital interface at a maximum rate of 49 frames/s at 62MHz. The NanEyeM, which is supplied as a Micro Camera Module (MCM) including a cable up to 2m long, features a custom multi-element lens which greatly improves the effective resolution of the sensor and reduces distortion. Compared to the earlier NanEye 2D sensor, which has a single-element lens, the new NanEyeM offers improved MTF (Modulation Transfer Function) of below 50% in the corners, lower distortion of less than 15%, and lower colour aberration of below Px. 

The new NanEyeXS has a 0.46mm2 footprint, making it one of the world´s smallest image sensors. It produces a digital output in 40kpixel resolution at a maximum rate of 55 frames/s at 28MHz. The sensor’s very small size offers significant advantages when developing ultra-small instruments for minimally invasive procedures, enabling the design of surgical devices with a very small diameter, or freeing more space for working channels in larger devices. Like the NanEyeM,the NanEyeXS is supplied as an MCM. 

The NanEyeM is also available in surface-mount chip form. 

In volume, endoscopes based on the new NanEye sensors will have a low enough unit cost to support the emerging single-use market. This has numerous benefits, including eliminating the risk of cross-contamination resulting from ineffective sterilisation, avoiding high maintenance costs and minimising the risk of disruption of operating theatre schedules when re-usable endoscopes are un-
available for use.
