High-Res CMOS Image Sensors Enable High-Performance Endoscopes

Sensor company ams latest NanEye family builds on its original miniature image sensor module for endoscopes, the NanEye 2D. The NanEyeM and NanEyeXS forecasts the production of high-performance, single-use endoscopes for use in minimally invasive surgery.

 

The 1-mm2 NanEyeM offers a 100-kpixel readout over an LVDS digital interface at a maximum rate of 49 fps at 62 MHz. It 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 >50% in the corners, lower distortion of <15%, and lower color aberration of <1Px.

 

The NanEyeXS has a 0.46-mm2 footprint, making it one of the world´s smallest image sensors. It produces a digital output in 40-kpixel resolution at a maximum rate of 55 fps at 28MHz. Like the NanEyeM, the NanEyeXS is supplied as an MCM.

 

The NanEyeM is also available in surface-mount chip form. The NanEyeXS and NanEyeM image sensors will be available for sampling in January 2019. More information is available by visiting ams.
