Title: Kan Ohtsuki - Innovator in Lens Meter Technology
Introduction
Kan Ohtsuki is a notable inventor based in Toyokawa, Japan. He is recognized for his contributions to optical technology, particularly in the field of lens measurement. His innovative approach has led to the development of a unique lens meter that enhances the accuracy of refractive power distribution measurements.
Latest Patents
Ohtsuki holds a patent for a lens meter designed to measure the refractive power distribution of progressive power lenses. This device features a lens rest with an aperture, an optical system that includes an axis, and a light source that projects a light bundle along the axis. The lens meter also incorporates a plate with targets and a two-dimensional image sensor that detects images as the light bundle passes through the lens, aperture, and plate. The device calculates the distribution within a measurement region based on detection results and can detect the lens position in a two-dimensional direction orthogonal to the axis. It guides movement on the rest to shift the measurement region, allowing for the analysis of distance, progressive, and near portions. The distribution is stored in association with the detected position, and the display part controls the visualization of the distribution map within the analysis region.
