DK-M3-FS and DK-M3-F Focus Module Developers Kits Tiny, all-in-one smart motion modules for positioning optics in OEM cameras FEATURING ams ICs: Tiny all-in-one solution: no external control board needed NSD-2101 piezo motor driver Superior image quality: sub-micron lens movement with very NSE-5310 linear position sensor low tilt. Now with higher dynamic stability APPLICATIONS Low voltage & power: 3.3 VDC input, zero power position hold High-resolution cameras for Simple system integration: accepts high-level motion miniaturized systems and handheld, commands over standard serial interface (I2C or SPI) portable or mobile instruments Flexible, production-ready system: compatible with M8 to In-vitro diagnostics (IVD) M16 lenses and with typical image formats from 1/3 to 1/1.8 Robotic inspection Lowest cost, fastest time to market: Fully-engineered plug Miniature microscopes and play solution Surveillance & remote sensing Biometric identification Imaging arrays Precision lens control for highest image quality Process control & machine vision M3-FS focus modules add high-resolution lens motion, with excellent Guidance, targeting & UAVs dynamic stability, to the smallest OEM cameras. Each module is a complete closed-loop motion solution and requires no more space than Your Camera a typical fixed lens mount. Very low power is needed to move the lens Board M3-FS and zero power is needed to hold the lens in any position, making the Module M3-FS ideal for battery-powered devices. Your M8 to M16 All M3 smart modules have embedded closed-loop control. They need only simple high-level motion commands from the camera processor, making system integration fast, simple and cost-effective. Precise lens position control (0.5 m resolution) and best-in-class bi- Small, precise and smart: M3-FS directional repeatability enable you to capture the sharpest images in and M3-F focus modules are easy to integrate. The complete, drop-in the shortest time. Designed for long life with high performance, M3 focus solution requires no more modules are not susceptible to temperature or power variations. space than a fixed lens holder. New aluminum construction with ball bearings for improved dynamic stability and precision The new M3-FS focus module is a drop-in replacement for the original M3-F focus module. The aluminum structure and innovative ball bearing guide mechanism deliver a 3x improvement in tilt and accuracy. The new M3-FS features superior dynamic stability, minimizing pixel shift with changing camera orientation. This makes it ideal for miniature handheld, portable and mobile systems. Maximum lens diameter is M16. All-in-one motion modules run The original M3-F focus module, with molded polymer construction and on 3.3 VDC and can be evaluated using a PC with USB adapter and a pin-bushing guide, remains an economical choice for lower precision New Scale Pathway software, requirements or fixed camera positions. Maximum lens diameter is M12. included in the Developers Kits. ams.com M3-FS and M3-F Focus Modules Simple integration Integration with camera processor Both the M3-FS and M3-F smart focus modules feature embedded closed-loop control.
