Achromatic Doublet

The history of the achromatic doublet

 

There's a lot of aspects of the scientific process which are wrapped in heavy debate. But of all of the subjects which people might apply that to one of the last on most people's minds would be lens design. But in reality there's a vast amount of debate and discussion wrapped up in the subject. One of the first was the creation of the basic telescope. It might not seem like a huge discovery to the modern mind. But the telescope was an amazing way to show the curvature of the landscape as ships sailed the sea. This, in turn, was proof that the world is a globe. Though of course one of the biggest milestones of debate within lens design came from the creation of the basic microscope. For the first time people were able to look through a lens and see a whole world of life which had previously been invisible. It's not hard to imagine how controversial that was at the time. And it continued as the microscope shed further light on the nature of biological life itself when applied to animal tissue. But surprisingly, many lens systems which seem innocuous from a modern perspective were also subjects of heavy debate.

 

Newtonian physics and the achromatic system

 

These days any achromatic lens such as an achromatic doublet can be designed and ordered online. But there was a time when no less important figure than Newton himself insisted that such systems were impossible. It wasn't until an ameteur, unaware of the theoretical limitations, tried his hand at it that the system could come into being. And this led to a revolution in how people not only see lenses but also some aspects of physics itself. And those lenses would themselves be used to expand that influence even further.
