Latest Patents
Kitamura's latest patents include a rod lens array and an image sensor head that utilizes the same technology. The purpose of this invention is to provide a rod lens array that features a deep depth of focus and a small depth of focus spot. This rod lens array is designed with at least one line of rod lenses positioned between two substrates. The line consists of multiple columnar rod lenses, where the refractive index decreases from the center to the outer periphery. The arrangement ensures that the center axes of the rod lenses remain substantially parallel to each other. The average depth of focus (DOFave) is at least 0.9 mm, while the depth of focus spot (DOFcv) in the scanning direction does not exceed 12%.
Another significant patent involves a light guide for a light source device, which includes a core layer made from a transparent resin. This core layer has a refractive index, with cladding layers on both surfaces that possess a lower refractive index. A light reflecting layer is incorporated to scatter and reflect light, enhancing the device's functionality. The design also features a light-emitting face and a recess that connects the cladding layer to the core layer.
