New Scale Technologies - M3-FS and M3-F Focus Modules
- Tiny “all-in-one” solution: no external control board needed
- Superior image quality: sub-micron lens movement with very low tilt. Now with higher dynamic stability
- Low voltage & power: 3.3 VDC input, zero power position hold
- Simple system integration: accepts high-level motion commands over standard serial interface (I2C or SPI)
- Flexible, production-ready system: compatible with M8 to M16 lenses and with typical image formats from 1/3” to 1/1.8”
- Lowest cost, fastest time to market: Fully-engineered “plug and play” solution
M3-FS and M3-F focus modules enable smaller instruments
M3-FS focus modules add high-resolution lens motion, with excellent dynamic stability, to the smallest embedded optical systems in handheld and portable instruments.
Each module is a complete closed-loop motion solution – including embedded controller – and requires no more space than a typical fixed lens mount. Very low power is needed to move the lens and zero power is needed to hold the lens in any position, making the M3-FS ideal for battery-powered devices.
M3-FS Focus Modules
M3 Focus Modules embed precision lens motion in miniature instruments. Input 3.3VDC and simple high-level commands from your system processor. No external control board needed.
M3-F Focus Modules
M3 Focus Modules incorporate a piezoelectric SQUIGGLE micro motor, built-in controller, position sensors and microprocessor on one tiny package.

All-in-one module, simple integration
All M3 smart modules have embedded closed-loop control. No external control board is needed. They take simple high-level motion commands directly from the camera processor, making system integration fast, simple and cost-effective.
Precise lens position control (0.5 µm resolution) and best-in-class bi-directional repeatability enable you to capture the sharpest images in the shortest time. Designed for long life with high performance, M3 modules are not susceptible to temperature or power variations.
New improved dynamic stability and precision
The 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 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.
The original M3-F focus module, with molded polymer construction and a pin-bushing guide, remains an economical choice for lower precision requirements or fixed camera positions. Maximum lens diameter is M12.
Developer’s Kits
The developer’s kit includes an M3-FS or 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 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”.
M3-FS and M3-F Developer’s Kits provide convenient engineering evaluation and demonstration of focus in your system.
New Scale Pathway™ software lets you easily evaluate the focus modules and validate your embedded software.
M3-F focus modules are easily integrated with your camera board and lens, and take up no more space than a fixed lens holder.

UV curing is a photopolymerization process in which UV energy is used to solidify liquids. UV LED curing systems are now the technology of choice across a wide range of applications including printing, 3D printing, coatings, and adhesives due to the inherent value of an LED solution. They offer vastly improved lifetimes, reduced maintenance costs, significant energy savings, and with no ozone emissions or mercury content, offer more benefits than traditional technologies. In addition, the “cold cure” offered by LED-based systems is ideal for heat-sensitive substrates or thin films.
