MgF2 on a crown glass surface provides reflectance around 1%, in comparison to 4% for bare glass. MgF2 coatings perform much better on higher-index glasses, especially those with index of refraction near 1.9. When the coatings are designed for a wavelength in the middle of the visible band, they provide reasonably good anti-reflection over the…
Carefully combining the stabilizer with the plastic can prevent this hazard, which explains why this method may be the most popular method of treating plastic with a UV absorber.
