Open Up the Future with LIGHT
Even in unknown fields, our wealth of knowledge and experience in the pursuit of the possibilities of optics and LIGHT, along with our spirit of never giving up and our will to overcome the most difficult challenges, enables us to help guide your development to a successful conclusion. Let’s work together to create the norms of the future with LIGHT.
HSFR, MSFR and LSFR controlled surfaces provide better reflectance in EUV and X-ray.
Our proprietary smoothing technologies reduce surface waviness and roughness.
Our optics support high efficiency and high performance in various fields including chip manufacturing and inspection in DUV range.
NATSUME signature optics.
Not only high precision surfaces, but also shapes such as cross-axis cylindrical surfaces and
composite monolithic cylinders with a spherical rear surface are also available.
Craftsmanship - Continuously refined grinding and polishing techniques for high-precision surfaces
Production started in 1977 - Sharp apexes and concave surfaces achieved through our polishing ability.
More than 15,000 of our axicons have been installed in a wide variety of manufacturing equipment.

Markets where NATSUME’s Optics are Installed
More than 90% of the DUV optics we manufacture and export are for the semiconductor market.
We work together with our customers from the development phase and communicate closely with them to take on the most difficult challenges.
We have a clean room and provide clean packaging.
Application: Lithography System, Defect Inspection System
Using the know-how garnered through our experience with optics for semiconductors, we manufacture high-precision mirrors for Space Observation.
Precision irregularity provides high strehl ratio.
High precision optics with low thermal expansion glass is available.
Application: National Space Observation Missions
NATSUME, in collaboration with the University of Tokyo, has developed a manufacturing process for soft X-ray mirrors that combines precision machining and precision replication technologies.
We have succeeded in highly efficient soft X-ray focusing with precision capillary mirrors at SPring-8.
Furthermore, we are a pioneer in the practical application of monolithic Wolter mirrors for soft X-ray.
We exhibit at trade shows as a place to hear the needs of our overseas customers directly.
We listen carefully and lead the challenge to a breakthrough.
Please feel free to consult with NATSUME about difficulties for which you have not yet found a solution.
We look forward to seeing you at the exhibition.
