Uniform flat-top light distribution for incident light! Usable in the visible to near-infrared range (400–1600nm).
The "FTD" is a diffusion plate with a micro-lens array formed on its surface that shapes incident light into a rectangular flat top (top hat). It is designed with a half-width at half maximum (FWHM) angle of 45°×35° and is mounted on protective rings of φ25mm and φ50mm. We offer the "FTD45x35PC30-D25/M" with a size of φ25mm and the "FTD45x35PC30-D50/M" with a size of φ50mm. 【Specifications (partial)】 ■ Diffusion angle (FWHM): 45°×35°±15% ■ Transmittance: >85% ■ Operating wavelength: 400nm to 1600nm ■ Operating temperature: -35℃ to 80℃ ■ Substrate: Polycarbonate ■ Thickness: 2.6mm *For more details, please refer to the related links or feel free to contact us.

Company information
Optical technology has become indispensable for advanced technologies and cutting-edge products. However, optical technology covers a wide range and is divided into many specialized fields. 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 to create a society where "products that change the future" are brought into the world just 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.
