Phone Case with Lens Mounting Systems
99 patents in this list
Updated:
Mobile photography demands precise optical alignment between auxiliary lenses and phone cameras, with tolerances measured in micrometers. Current attachment mechanisms struggle to maintain consistent positioning through daily use, leading to image degradation, vignetting, and focus inconsistencies that become particularly noticeable in low-light conditions.
The fundamental challenge lies in creating secure lens attachment systems that maintain perfect optical alignment while allowing for quick lens changes and protecting the phone's built-in optics.
This page brings together solutions from recent research—including self-aligning lens interfaces, waterproof modular systems, integrated lens recognition systems, and optimized protective coatings. These and other approaches focus on practical implementations that balance optical performance with everyday usability and device protection.
