It is used for the design and analysis of optical systems.

This can be used to determine the state of the optical system at any point in time.

Older systems used a microscope optical system with a back light.

Optical systems typically fall into one of two different categories.

We'll get to the new stuff in a minute, but let's begin with a look at why current optical systems are hitting the wall.

Low energy electron optical systems are also hard to design for high resolution.

An error of that magnitude is considered huge for a complex optical system.

Other optical systems do not use the "mirrors" technology, and are considered more robust.

Two such points are called a stigmatic pair of the optical system.

Single beam machines have simple optical systems and are more compact.

Rather than illuminating objects, they simply measure what is received through the optical system.

The resolution of all optical systems is limited by diffraction.

Details of a specific TV set with its optical system can be found here.

Today this technology seems old hat, with only an optical system and no thermal imaging.

This effect is often used deliberately in complex optical systems, especially certain types of telescope.

Catadioptric combinations have been used in many early optical systems.

Detailed knowledge of the optical system used to produce the image can allow for some useful correction.

He thought this would create a sealed and rugged optical system suitable for use in schools.

The optical system consists of two mirrors and, generally, a low power telescope.

Etendue is important because it never decreases in any optical system.

Their poor transparency is a concern in case of optical systems and solar panels.

Starting in 1965 a large optical system was added to the spacecraft for military reconnaissance.

The company produced range-finders and other optical systems for the German military.

He carried out fundamental work for the theory of aberration in optical systems.

"At one point in his life he worked at a company that made optical systems.
