Reflection coefficients of surfaces can be reduced to less than 0.2 %, producing an " antireflection " ( AR ) coating.
12.
Traditionally, DFBs are antireflection coated on one side of the cavity and coated for high reflectivity on the other side ( AR / HR ).
13.
Matte displays feature a light-scattering antireflection layer, which reduces reflectivity at the cost of decreased contrast and color intensity under dimly lit conditions.
14.
These modules are produced by depositing an antireflection coating and doped silicon onto textured glass substrates using plasma-enhanced chemical vapor deposition ( PECVD ).
15.
If the rod has an antireflection coating, or is immersed in a fluid that matches its refractive index, it can dramatically reduce these parasitic reflections.
16.
Practical antireflection coatings rely on an intermediate layer not only for its direct reduction of reflection coefficient, but also use the interference effect of a thin layer.
17.
In this case the grating forms the distributed mirror on the antireflection coated side, while the semiconductor facet on the high reflectivity side forms the other mirror.
18.
The Double Gauss became the preferred normal lens design in the 1950s with the availability of antireflection coating and new generation extra high refractive index rare earth optical glasses.
19.
The reflections inside the prism are not caused by total internal reflection, since the beams are incident at an angle less than the antireflection coating to reduce spurious reflections.
20.
The differences may include using calcite selected for low scattering loss, improved polish quality on the faces and especially on the sides of the crystal, and better antireflection coatings.
