When people thing of optical systems they usually think of the lens. It's a natural assumption since this is usually the focal point of less advanced devices. For example, consider eyeglasses. The frames certainly have some importance when it comes to fashion. And they do have some functional aspects to them as well. But for the most part they're just a simple structure which serves to keep the complex lens system on top of one's eye. Telescopes present a similar idea to people. With the lens being the focal point and everything else being about keeping them in place. And then there's things such as contacts which might well be said to consist of nothing but the lens. So it's easy to see why people might think of the lens as the totality of an optical system. But what people forget is that modern technology has had an immense impact on almost everything in the world. If people have created it than it's probable that high tech computational systems have been integrated into it to some extent. And the world of optical design is no exception. In reality there's a huge complexity to be found within modern day Optical components.
How to ensure that every component is up to spec
But there's one big issue with the modern day complexity of optical systems. That's the fact that testing them isn't nearly as simple as it once was. Back in the day testing an optical system could be either done within a few seconds by hand or through fully automated systems. But today the testing phase can require expert care. This is one of the reasons why companies that supply an around the clock staff of experts is so important for anyone who needs their Optical components put together and tested in a very short time span. It's only through expert care that one can be sure of the results.
