M3-F Focus Module
Miniature micro-mechatronic
smart module for precision focus
FEATURES
 Small: complete, compact system with integrated controls
and firmware – no external control board needed
 Superior image quality: micron-precision lens movement
with very low tilt
 Low Voltage, low power use: runs on 3.3 V DC input,
holds focus with power off
 Simple system integration: accepts high-level motion
commands over standard serial interface (I2C or SPI)
 Flexible, production-ready system: compatible with M8 to
M12 lenses and standard imager formats (e.g. 1/2" and 1/1.8")
APPLICATIONS
Miniature, high-resolution
cameras
 Biometric systems
 Infrared cameras
 Medical diagnostic and
inspection systems
 Miniature video cameras
and computer cameras
 Projectors
 Targeting systems
 Cost-effective system solution: single-lens system with
embedded closed-loop drive circuit for high repeatability with
low external processing requirements
Precision lens control; superior image quality
M3-F focus modules add high-resolution lens motion to the smallest
OEM cameras. A complete closed-loop motion solution, the M3-F focus
module is no larger than a fixed lens holder and has low power
requirements for use in battery-powered devices.
The M3-F smart module gives you a single-lens focus solution with
minimal external processing requirements, making it simple and costeffective to integrate focus into your camera system. Precise lens
position control (0.5 micron resolution) and best-in-class bi-directional
repeatability enable you to capture the sharpest images from your
board-mounted camera system.
M3-F modules are designed for long life, with high performance that is
not susceptible to temperature or power variations.

Flexibility and Precision: M3-F
modules are easily integrated with
your camera board and lens. The
M3-F is a complete, drop-in focus
solution that requires no more
space than a fixed lens holder.
The M3 micro-mechatronic platform
New Scale’s M3 Micro-Mechatronic Module technology platform
provides the smallest, highest resolution and most repeatable closedloop micro-mechatronic systems available –in easily integrated,
customizable packages. M3 smart modules include a patented
SQUIGGLE® RV piezo micro motor, an NSD-2101 drive ASIC, an NSE5310 high-resolution magnetic position sensor, and a microprocessor.
These combine to create the world’s smallest closed-loop linear motion
systems, with performance comparable to much larger systems.
