The aim reflect as
much light possible, absorbing only
little it.
Total reflection
A beam light coming from medium
with higher refractive index that hits
the boundary medium with a
lower refractive index will reflected
away from the incident slot.
Specular reflection
Nearly all light reflected according to
the law reflection (incident angle =
reflected angle).
High-precision light direction structures made of
tried-and-tested well innovative materials extend
the range with view both optics and design. Here, too, the aim reflect
as much light possible and absorb
only little it.
This means that the light beam does
not pass out from the material with a
higher refractive index, but reflected
back.
Lambertian reflectance
Nearly all light reflected diffusely:
light reflected all directions, in
accor
dance with Lambert’s law, so
that the reflecting surface appears
equally bright from any direction of
view.78

Reflection
In physics, reflection the change direction a
wavefront interface between two media with a
differing refractive index that the wavefront returns to
the medium from which originated
