Simple integration

Integration with camera processor

Both the M3-FS and M3-F smart focus modules feature embedded

closed-loop control. You provide simple, high-level motion commands

from the camera processor over a standard I2C or SPI interface.

Lens installation and alignment

Install your lens using the threaded inside diameter of the M3 module.

The M3-FS accepts a maximum M16 diameter lens, or an M12 lenses

with a standard adapter. Smaller lenses may be feasible depending on

the optical design. The M3-F accepts a maximum M12 lens directly.

For typical camera integration, “active alignment” is required to align

the optical centerline of the lens orthogonal to the image sensor by

moving the M3 module and lens as a single assembly.

After alignment, the base of the module is typically secured to the

image sensor board using shims, adhesive and screws. The lens

back focal distance is then set by rotating the lens in the threads and

securing it with a small amount of adhesive in the threads.

Note 1: Fixed orientation may allow for heavier lens operation. Please consult the factory.

Note 2: Power depends on input voltage, speed & load.

Note 3: Consult the factory for lower temperature requirements.

Note 4: M3-FS specification corresponds to 10 million moves with average random move of 120 µm. Lifetime depends on application and use case. Please consult factory to discuss your

specific system design.

Specifications

The M3 Advantage: New Scale’s M3

micro-mechatronic module platforms

provide the smallest, highest resolu-

tion, and most repeatable closed-loop

positioning solutions available. These

“all in-one” smart modules require no

separate electronics and are ready to

plug-and-play directly with your

system processor and power supply.

You achieve the fastest time to market

with the lowest total cost.

Each M3 smart module is a fully en-

gineered solution that integrates our

patented and proprietary motor, drive,

sensing, guide and control technolo-

gies. These unique components com-

bine to create the world’s smallest

closed-loop motion solutions.
