1mm Acrylic Diffuser Sheet
1mm Acrylic diffuser sheet custom LED light frosted clear plastic
PMMA plate
1. Product Description
The main feature of acrylic diffuser sheets is their ability to
scatter light, altering the beam angle to 160–176°,
no matter the original light distribution. This results in a foggy
surface effect, which reduces illumination
intensity. The wider the beam angle, the lower the light intensity,
with some wavelengths being blocked,
causing color shifts. Surface treatments like sanding or embossing
further reduce light transmittance.
Therefore, it's essential to choose a base material with a low
refractive index to minimize light interference and
optimize diffusion for displays and signage.

3. Optical eigenvalues
Generally, for the quality control of optical properties of
transparent and translucent plastics such as plate,
sheet, film, and tube, the indicators such as transmittance and
haze are mainly evaluated by testing.
a.Light Transmittance
The percentage of light passing through the material compared to
the light hitting the sample. It indicates how
much light is transmitted through a diffuser, directly affecting
display brightness.
b.Haze
The percentage of scattered light deviating from the incident
direction. A higher haze value means more
scattering, which can soften light, improving visual comfort but
reducing clarity.
c.Refractive Index
Affects both light transmittance and haze. A higher refractive
index lowers transmittance and increases
scattering. This is crucial for selecting materials that balance
light diffusion and transparency for optimal
display performance.
