Control the "diffusion" of light. An optical sheet that efficiently improves lighting unevenness with a high transmittance rate of 85-92%.
"LSD" is a diffusion sheet and light diffusion film that shapes and diffuses light through the diffusion function of a micro-sized, randomly arranged lens array, eliminating lighting unevenness. It allows for efficient lighting by distributing light only in the necessary areas. We offer materials that can be used with ultraviolet, visible, and near-infrared light, making them suitable for any wavelength. Micron-sized lenses are arranged in a completely random state on polycarbonate or acrylic sheets. This completely eliminates the brightness unevenness of the light source while providing highly homogeneous light that diffuses at any angle. Additionally, its transmittance is very high (85-92%), allowing for the effective use of the light from the source without waste. [Features] ■ Very high transmittance of 85-92% ■ More than 8 types of circular diffusion and more than 4 types of elliptical diffusion available ■ Radiation intensity follows a Gaussian distribution, ensuring high uniformity ■ Compatible with LED, halogen, and laser light sources ■ No color separation even with white light *For more details, please refer to the PDF document or feel free to contact us.

Company information
Optical technology has become indispensable for advanced technologies and cutting-edge products. However, optical technology encompasses a wide range of fields, with specialized areas that are finely divided. Even when concepts realized through optical technology hit a wall, there are not many places to consult for solutions. We are experts in problem-solving specialized in optics. We provide solutions for the development of optical systems and optical units that respond to various properties of light, from the conceptual stage to prototyping and mass production, all in one go. Our goal is a society where "products that change the future" are created as envisioned by engineers. A society where "concepts that change the future" are realized in the shortest time possible. If such a society is realized, people's lives will become more convenient and prosperous. We believe in the diverse and great power of optics, and today, we continue to resolve the "troubles" of optics with clarity.
