Module assembles directly to board-mounted camera,
accepts a standard threaded lens, operates on 3.3V and accepts
high-level digital motion commands
Victor, NY - June 7, 2010 – New Scale
Technologies, Inc. today announced its M3-F
focus module for miniature OEM cameras used in handheld
products; portable biometric sensors; targeting, surveillance and
security systems; and medical diagnostic and imaging devices. At
only 20 x 22 x 18.5 mm – about the same dimensions as a fixed lens
holder – the M3-F focus module improves image quality over a wide
range of focus distances without adding volume or significantly
increasing power usage.
All lens motion functions are fully integrated in the M3-F module
including actuator, position sensor, guide mechanism, drive and
control electronics and software. This extreme level of
miniaturization and integration highlights New Scale’s
micro-mechatronics capabilities.
With on-board closed-loop PID control, M3-F modules are designed for
ease of integration. The microprocessor accepts PID closed-loop
system tuning commands, as well as high-level input commands such as
“move specified distance,” via standard serial interface (I2C, SPI
or USART). No external controller is needed.
Modules provide millimeters of lens motion with 0.5 µm position resolution, better than 30
µm accuracy, and better
than +/-0.5 degree angular alignment. Based on New Scale’s
M3
micro-mechatronics module design platform,
the M3-F modules are quickly customized to OEM specifications for
lens (from M8 to M12 size, up to 5 grams mass), image sensor, focal
length, board camera PCB mounting pattern, and other requirements.
M3-F modules accept 3.3V input voltage for battery-powered
operation. They draw approximately 470 mW of power while moving and
130 mW quiescent. Weight is approximately 6 grams without lens.
“The M3-F incorporates New Scale’s state-of-the-art precision
miniature mechatronics into a focus module for the precise
positioning required by today’s high-resolution camera systems,”
said Ralph Weber, product manager at New Scale. “Integrating the
motor driver, position sensor and microprocessor right into the
module dramatically simplifies system integration for our customers,
and our flexible M3 design platform enables us to create customized
modules very quickly for each OEM.”
M3 Platform advances New Scale’s focus technology
The M3-F modules advance New Scale’s custom focus module technology
by:
- Integrating the drive electronics in the module, reducing system
size and weight.
- Adding a microprocessor in the module for closed-loop PID control,
simplifying system integration for OEM users.
- Building on New Scale’s new M3 Micro-Mechatronic Module Design
Platform, facilitating rapid customization.
Each M3 Micro-Mechatronics Module incorporates a patented
piezoelectric SQUIGGLE micro motor, a motor drive ASIC, a TRACKER
magnetic position sensor, a microprocessor and a motion mechanism in
a compact housing. M3 modules are smaller, more powerful, more
precise and even easier to integrate than traditional
electromagnetic motor systems.
Price and availability
M3-F production modules are customized to OEM specifications.
Pricing and delivery depends on specifications and volume. Custom
prototypes are typically available 8 to 10 weeks after acceptance of
proposal. RFPs can be submitted online at
http://www.newscaletech.com/contact_AF-RFP.aspx.
M3-F Developer’s Kits include an M3-F focus module along with a USB
key and New Scale Pathway PC software. This gives designers a
graphical user interface to drive the lens holder and evaluate its
motion. Lens and image sensor are not included in the kit. For more
information, including a lens and image sensor compatibility
checklist, visit http://www.newscaletech.com/M3-F.html.
Developer’s Kits are $750 and will be available in July 2010.
