M3-F Focus Modules

Precision focus for the smallest OEM cameras

M3-F customizable focus modules add precision lens motion to the smallest OEM cameras. M3-F modules are small enough to replace fixed lens holders and simple to integrate into your camera system.



Improve performance of miniature cameras for biometric detectionmedical devices and imaging, video cameras, computer cameras, projectors and targeting systems.

The application note M3-F focus modules in camera system design describes the use of the M3-F module in camera systems. It includes module details, comparison to other focus techniques, block diagrams and integration information, and discussion of bi-directional vs. uni-directional repeatability and other performance considerations.


Developer's Kits

The developer's kit includes an M3-F focus module that you can control from your PC using our New Scale Pathway™ Software. This provides a simple and powerful platform for easy evaluation of the module as well as for your system development. You can interface directly to the module via its serial interface for prototyping. 

The M3-F modules in the developer's kits can accept a broad range of lenses and accommodate image sensors up to 17 x 17 mm including 1/2" and 1/1.8" formats.  (The lens and image sensor are NOT included in the kit.) For lens recommendations and guidelines for determining your image sensor and lens compatibility, please read the design note “Checking Optical and Imager Geometry in DK-M3-F”.

Kits are available to qualified OEMs as part of a development program with New Scale, or for purchase from select distributors.
