Types Of Optical Coating For High Performance

In this colorful world we are living in, one needs to properly see how everything looks like. One can only fully appreciate the beauty of this world if you can accurately see your surroundings.

However, there are times when one cannot achieve the desired effect due to a variety of factors. Among these factors, the most renowned of them all is reflection.

Technically speaking, a reflection is produced when light, instead of passing through two mediums with different refractive indexes, bounces of instead. The result? Lesser light making its way through the medium, hence, lesser visual acuity and image contrast.

However, thanks to the latest technology that ECI uses, one can already address this problem with the help of optical coatings.

What is an optical coating?

  • One or more thin layers of material that are deposited on any optical component available, like a mirror or a lens
  • It alters the way that optical component reflects and transmits the light passing through it

Types of optical coatings available in the market

  1. Metal coating
  • Simplest optical coating available in the market
  • Makes use of thin layers of metals (aluminium, silver, or gold)
  • Metal used is deposited on to the glass substrate in a process called silvering
  • The reflective properties of the mirror depends on the metal used
  • Dielectric coating
  • Application of materials with different refractive indexes to the substrate
  • Materials commonly used: magnesium fluoride, calcium fluoride, and other metal oxides
  • Commonly used method in producing scientific optical instruments (microscopes, telescopes, interferometers) and consumer devices (binoculars, spectacles, lenses)
  • Antireflection (AR) coating
  • Reduces the reflection given off from surfaces, hence, reducing reflection
  • High-reflection coating
  • Works the opposite of AR coating
  • Makes use of high-index (zinc sulfide, titanium dioxide) and low-index (magnesium fluoride, silicon dioxide) to enhance reflectivity through a band-stop.
  • Extreme ultraviolet (EUV) coating
  • Makes use of multilayer layers of mirrors  made of high-mass metals (molybdenum, tungsten) and a low-mass spacer (silicon, vacuum) to be deposited on a substrate
  • Transparent conductive coating
  • Used where coatings should conduct electricity or produce static charge

How To Tell If A Credit Card Number Is Real

There are many reasons why the used of credit cards nowadays are so popular. Aside from the fact that it is very convenient knowing that you don’t have to carry a big amount of money in your wallet instead you just have to present the card, credit cards also perform a big role when shopping online. However, make sure that you can identify the fake credit cards from the real ones knowing that it is possible to obtain free credit card numbers.

Guide to Identify a Fake Credit Card
If you are managing a store, for sure it would be necessary that you have an idea on how to identify real credit card numbers. Remember that free credit card numbers are widely available online so if you don’t want to become a victim, then you should educate yourself about how to spot a fake credit card number. This is when you should learn more about the Luhn check digit algorithm. This is a mathematical test wherein you will have to manipulate the number or follow an equation to check if the result is divisible with 10.

For a credit card with even number digits, you have to double the alternating numbers by starting with the first digit. On the other hand, for cards with odd number digits, you have to start with the second digit. If ever that the sum is a double digit number, you need to add the numbers to get a single digit result. After that, you have to go back to the real credit card number and change the doubled digits with the new number, then add them together. Once you get the sum, you will have to check if it is divisible with 10. If ever that the number is not divisible with 10, then it only means that the number is not valid.
