“…Optical lenses, biochips, and fuel cells, which are used as core components in various high-tech industries, are fabricated in a form that consists of a microstructure on the surface [1][2][3][4][5][6]. In particular, a head-up display device mounted on an aircraft or a vehicle, or a head-mounted display device for realizing a VR (virtual reality) and an AR (augmented reality) requires a high-performance lens.…”

The shape accuracy of microstructures is an important factor that directly affects the quality and performance of products. Nevertheless, it is difficult to find a study for the shape accuracy of microstructures below several microns. This study aimed to reduce the shape error in the precision machining of microstructures with a repeated triangular cross-sectional shape with a width of 5 µm or less. Two important factors in this study were the morphological features of the microstructure to be fabricated and the cross-sectional shape of the chip. The tool path was modified in consideration of these two factors. Before the tool path change, the shape error due to the deformation of the triangular micropattern in a DOC (depth of a cut) of 1 µm was about 0.39 µm. However, after the tool path was modified, the shape error due to deformation did not occur while maintaining the DOC at 1 µm.

“…Finally, due to the extreme different dispersive characteristics of DOEs, compared to refractive lenses, they allow an advantageous combination of both to form hybrid imaging systems with optimized performance and compactness. To name a few, the imaging hybrid concept was applied to eyepieces [1][2][3][4][5], head-mounted displays (HMDs) [6][7][8], inspection systems for semiconductor manufacturing industry [9,10] and also for new concepts of space telescopes [11,12]. In this field, the activities of the Japanese company Canon attracted very high interest.…”

Abstract:In the last 20 years, diffractive optics experienced a strong research interest and was in the center of many development projects in applied optics. To offer a side view for optical engineers, here, we discuss selected, businessrelated aspects of the current status of the transfer process to bring diffractive optics into commercial products. The contribution is divided into two parts. Here, in part I, we focus on the patent landscape of diffractive optics with a closer look on the temporal development and the distribution over main players. As an important result, currently, new strong patent activities are observed especially in the context of imaging systems. In the second part, the business volumes of selected market segments are discussed.
