Liquid Lens CM – AF and OIS Integration
The integration of AF and OIS within a liquid lens module offers photographers and device manufacturers a powerful tool for capturing exceptional visuals. Whether you’re taking a snapshot or recording a video, this technology ensures clarity and stability.
Key Features
Auto-Focus (AF)
-
The mechanical motor adjusts the curvature of the liquid lens.
-
By changing the lens shape, the focal length can be modified rapidly.
-
This dynamic adjustment ensures precise focus on the subject, whether it’s near or far.
Combined Benefits
-
Premium lens coatings minimize flare, distortion, and chromatic aberrations.
-
Ensures sharpness across the entire frame.
Optical Image Stabilization (OIS)
-
The same mechanical motor can also apply controlled pressure to the liquid lens membrane.
-
When the camera experiences shake or movement, the liquid lens compensates by adjusting its shape.
-
OIS minimizes blur caused by camera shake, resulting in sharper images and stable videos.
Applications
Smartphones: High-speed focusing and improved image stability.
Industrial Cameras: Precise imaging in manufacturing and inspection.
Medical Devices: Endoscopes, diagnostics, and surgical imaging.

OIS Evaluation System
What is OIS?
Optical Image Stabilization (OIS) is a technology used in cameras and lenses to reduce blurring caused by camera shake during exposure.
It compensates for unintentional movement of the camera or imaging device, resulting in sharper photos and steadier videos.
How Does OIS Work?
OIS systems use mechanical or optical components to stabilize the image during capture.
Common methods include:
-
Lens-Based Stabilization:
-
Lens elements are physically shifted to counteract camera shake.
-
Commonly found in high-end cameras and stabilized lenses.
-
-
Sensor-Shift Stabilization:
-
The image sensor itself is moved to compensate for motion.
-
Often used in mirrorless cameras and some DSLRs.
-
-
Hybrid Systems:
-
Combine both lens-based and sensor-shift stabilization for optimal results.
-
Why Is OIS Important?
Low-Light Performance:
-
OIS allows longer handheld exposures without introducing blur.
-
By stabilizing the image, it enables cleaner, crisper low-light photos.
Versatility with Long Lenses:
-
OIS helps photographers shoot at slower shutter speeds, especially with telephoto lenses.
-
It eliminates the need for a tripod in many situations.
Video Stability:
-
OIS reduces jitter and frame-to-frame shake in recorded videos.
-
Ensures smoother, more professional-looking footage.
Viewfinder Stability:
-
OIS stabilizes the view through the viewfinder, aiding composition and focus accuracy.
-
Particularly useful with long telephoto lenses.
In summary, OIS enhances image quality, expands creative possibilities, and ensures better results in challenging shooting conditions. Whether you’re capturing stills or recording videos, OIS is a valuable tool for every photographer and videographer.
