Revolutionary MEMS autofocus actuator for active athermalization in embedded vision cameras
Problem
Sheba Microsystem’s revolutionary MEMS autofocus actuator for active athermalization in embedded vision cameras used in drones, action cameras, automotive, machine vision, and mobile robotics. Embedded vision cameras often face challenges in maintaining image quality and focus stability during temperature fluctuations as the optics undergo thermal expansion. While smartphones use electromagnetic autofocus actuators, they are not reliable for embedded vision cameras due to extreme environmental conditions and larger optics. Other autofocus systems in-market such as tunable lenses lack thermal stability and compromise optical quality.
Solution
Active athermalization and autofocus MEMS actuator
Provides consistent highest-quality imaging for drones, action cameras, automotive, machine vision, and mobile robotics regards of temperature fluctuations and mechanical shocks
- Thermally stable (-40 to 150 deg.) Fast < 2ms response time
- Low power
- High precision <0.5 um
- Less sensitive to mechanical shocks
- No hysteresis
- No electromagnetic interference
Use Cases
Automotive
Unleashes potential of highest resolution imaging possible in forward-facing cameras.
Sheba’s technology ensures accurate object detection, enhances safety, and is ideal for autonomous vehicles and AI image processing, where image quality is paramount, and split-second decisions based on those images matter
The extreme test conditions of automotive environments made it challenging for any autofocus technology to penetrate.
Sheba AF actuators are highly thermally stable actuators for the automotive market.
Action Cameras
Provides autofocus and active athermalization even in high action scenarios. The high mechanical shocks (in the range of 10’s of g’s) in action cameras (such as dirt bike driving) makes it challenging to use autofocus actuators.
However, Sheba AF actuator has extremely low sensitivity to mechanical shocks while providing autofocus.

Solution Two
Compact Cameras
Smartphone selfie cameras, AR / VR, laptops, tablets, and notebooks.
Sheba MEMS autofocus actuators are well suited for the use in compact cameras as they extend the battery life, enables the use of high quality optics- as the sensor moves instead of the optics- and offers high speed autofocus feature.

Use Cases
Smartphones
VCM driven AF selfie cameras rapidly consume the battery of smartphones with heavy use of streaming (e.g. video calls).
Since the VCM is placed around the optics, it occupies a relatively wider space of the front display.
