Latest Patents
Kawada holds two patents, showcasing her expertise in lens technology. Her latest inventions are:
1. **Zoom Lens**: This innovative zoom lens features a sequential arrangement starting from the object side with a stationary first lens group possessing positive refractive power. It includes a second lens group that has negative refractive power and moves along the optical axis to change magnification. The design ensures effective correction of distortion and off-axis aberration on the wide-angle side, resulting in a high-performance and compact zoom lens with a significant variable magnification.
2. **Fisheye Lens Unit**: In this invention, Kawada provides a technique for creating a fisheye lens unit with a minimal number of lenses. The lens unit uses a predetermined projection method, ensuring that the variation in image height relative to incident angle is maintained. The structure consists of a first lens group on the object side, a second lens group on the image side, and an aperture stop in between. The final lens in the second group is an aspheric lens designed to improve optical performance.
