1mm Acrylic Diffuser Sheet
1mm Acrylic diffuser sheet custom LED light frosted clear plastic
PMMA plate
1. Product Description
The biggest feature of the acrylic diffuser
sheet is that it causes a lot of interference to the light. No
matter how many degrees the light distribution curve of the
original design is, as long as the light passes through the
diffuser, it will change the beam angle to 160~176°. There is a
foggy feeling on the board surface. From this point, it can be
proved that the beam angle is as large as 160~176°. The best proof
is that the larger the beam angle, the lower the illumination, and
some will filter light, so that some wavelengths cannot be
penetrated. , resulting in color shift, such as re-light
interference treatment on the surface (for example: sanding,
embossing), the light transmittance is even lower due to the
natural phenomenon of geometric optics, so the base material used
to make the diffuser plate should choose the refractive index The
lower the better, the lower the interference with light.

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. Our country was proposed by
the former Ministry of Chemical Industry of the People's Republic
of my country, drafted by the former Ministry of Chemical Industry
Chenguang Chemical Research Institute and other units, and issued
by the State Administration of Standards. ". which are defined as
follows:
1. Light transmittance—the ratio of the luminous flux
(Luminous Flux) passing through the sample to the luminous flux
hitting the sample, expressed as a percentage.
2. Haze—the ratio of the scattered luminous flux
deviating from the incident light direction through the sample to
the transmitted luminous flux, expressed as a percentage (for this
method, only the scattered luminous flux deviating from the
incident light direction by more than 2.5 degrees is used to
calculate the haze) . The cloudy or cloudy appearance of the
interior or surface of a transparent or translucent material due to
light scattering. Expressed as a percentage of the ratio of the
scattered luminous flux to the luminous flux transmitted through
the material. It is an important parameter for the optical
transparency of transparent or translucent materials.
3. Refractive index-----no matter how your
transmittance or haze changes, it has already determined its optics
in terms of quality (density). The higher the refractive index, the
lower the transmittance, which has nothing to do with thickness.
Both light transmittance and haze are indicators to measure the
transparency of materials, which are not necessarily applicable to
diffusers. Generally speaking, there is an inverse relationship
between light transmittance and haze, and vice versa.
