Focusing on the Field of View

May 7, 2021

When magnification was as simple as one eyepiece and one objective, finding your total magnification was as easy as multiplying the two values together. The addition of film brought a third value to the equation, but the result remained a static, concrete number.

And then along came the computer.

With a huge variety of video camera chips and monitor sizes and camera couplers and screen resolution, suddenly viewing something at 500X magnification became much more challenging. There was no way to take into account all of the permutations possible. For example, even if two systems were otherwise exactly the same, but one had a 23" monitor and the other had a 24" monitor, the magnification would be different.

It was time to replace the magnification focus with a different way of looking at things: the Field of View (F.O.V.)

A Tip on Met Tips

October 10, 2019

Let's be honest, metallography is not exactly the biggest field out there. If you're struggling with your computer, you can ask the internet "why did this error message come up?" and get some troubleshooting advice, but if you try typing "Why do I have radial cracks?" into a search engine, you'll more likely end up with an article about tomatoes than you will an explanation of what could cause a radial crack in a prepared mount and how to prevent it.

That's where we come in.
