Proposal for masks with ultra-fine slits, coded masks with high aspect ratios, and collimators.
◆Proposal for Masks Using our fine pore processing technology with a minimum hole diameter of φ0.1μm, we propose precision fine masks through continuous irradiation without cutting the beam, allowing for straight and curved slit processing. The thickness between slits can be made adjacent up to about 2μm, and by utilizing our available equipment, the slit width can be freely selected. However, there is a relationship of work thickness/slit width ≦ 5. ◆Proposal for Coded Masks By leveraging metal 3D printing technology, we propose collimators and coded masks that, while not in the ultra-fine area of beam processing, do not have the constraint of work thickness/slit width ≦ 5, allowing for free design of complex shapes.

basic information
Long Pulse Laser By adding heat more efficiently, it enables high-speed and high-quality processing of micro-holes and porous materials. Furthermore, by combining it with preceding and subsequent processing steps (precision machining technology), it allows for low-cost processing. Ultra-Short Pulse Laser Processing A processing method that uses lasers with very short pulse widths (picoseconds, femtoseconds, etc.) for fine machining. It has minimal thermal effects and results in high-quality finishes. Focused Ion Beam Device (FIB) By scanning a focused ion beam, which is concentrated to a few tens of nanometers, across the sample surface, it can detect secondary electrons and observe microscopic images or process the sample surface. Laser Powder Bed Fusion (L-PBF) A method where a laser is irradiated onto a bed covered with metal powder, causing melting and layering. It is suitable for high-precision shaping of relatively small and complex shapes. Direct Energy Deposition (DED) A method where a laser is irradiated onto metal powder that is being sprayed, causing melting and layering. It is suitable for large-scale shaping, partial shaping, and repairs of existing products.

Company information
Precision micro-machining technology is increasingly recognized as a common foundational technology that supports modern advanced industries. Since its establishment in 1955, Toray Precision Co., Ltd. has manufactured spinnerets, which are key technologies for synthetic fiber production, and has contributed to the development of the synthetic fiber industry by providing them to fiber manufacturers worldwide, including Japan and Europe and the United States. Meanwhile, the experience and technology gained during this time in precision micro-machining have been widely applied to other industrial sectors. Precision machined components are incorporated into critical parts of aircraft, industrial robots, measurement and control equipment, etc. Additionally, the specially developed and designed fluid nozzles have demonstrated their functionality as important components in various industrial machines. The ultra-precision micro-machining technology, boasting sub-micron precision, is also utilized in the optical communication field, which is essential for realizing a highly information-oriented society. We have also commercialized various optical devices, including optical components such as ferrules and adapters. As a pioneer in ultra-precision micro-machining technology, we will continue to contribute to society by delivering high-precision, high-quality products.
