Neutral density filter "Diffraction type diffusion plate"

Various diffusion levels available! Filters that are optimal for adjusting light intensity when measuring the optical properties of light sources.

The "diffraction-type diffusion plate" is not only used to diffuse light, but also offers various degrees of diffusion, making it ideal for adjusting light intensity when measuring the optical characteristics of a light source. The diffusion plate is used to spread light from the source, providing uniform light without unevenness. In particular, it contributes to improving the repeatability concerning reproducibility during color measurement of the light source. The diffraction-type diffusion plate (hereafter referred to as LSD) effectively reduces the measurement dispersion of chromaticity compared to standard diffusion plates and ND filters, and it allows for variable light intensity by selecting the divergence angle. 【Features】 ○ Equivalent effect to lenses ○ Freedom of light source selection ○ High transmittance ○ Light distribution control For more details, please contact us or download the catalog.
