It is difficult to gauge human beings regarding their likes and dislikes because everyone has his/her own mindset and perspective while the human psyche in itself is totally unpredictable as the interest over certain topics keeps on fluctuating from time to time.
So you can imagine what would be the interest rate if the topic involves something like quantum physics or chemistry with complicated mathematical equations and calculations and that is the last thing in the world that the current generation is interested in for obvious reasons.
Optical Coating is in the same mould but it is a mixed bag as people interested in physics would love to know more about it while those for whom rocket science is way beyond their capabilities are wary of it, not that they are any less in any manner just because they aren’t interested in this field of course.
Lighting up the Mind
Where to begin with a topic so complex that it boggles the mind but for starters, optical coating is a definitive set of thin layers that are deposited onto optical instruments like lens and mirror but in a very subtle manner so that they are properly altered so that the light can be reflected and transmitted from one layer to another.
It is most often used for camera lenses where the surface is cleaned with the help of antireflective coating which can be considered a subset of optical coating where it reduces the reflection on the lenses to give it a blurry look.
As is known that camera lenses are of different varieties to match with different models but the reflection has to be perfect so that the picture is clear enough to be visible to the naked eye.
This is very well known to photographers who take dozens of pictures each day through their cameras as they have sound knowledge about lenses, cameras, wide angles and other things.
So this information would light up the mind of many people especially people that are interested in taking up photography as a profession but optical coating is of many different types that we will now look into to further our knowledge.
Subset of Optics
Optical coatings are made from thin layers as mentioned above where metal is the natural alloy as it is easily available that are used as deposits on substrates of glass in order to conjure up a proper mirror surface and is called silvering.
Next comes silver where which are obviously costlier than metals but here the reflection is decreased so that ultraviolet regions are more visible but it has around 68-72% of electromagnetic radiation.
Finally there is gold which is the costliest of all where the reflection rate is nearly 99.99% and the radiation level is also quite strong but the wavelength is shorter at around 530nm which is the source of the bright golden color.
