Coatings of this design are still used today for multigas cavity...Photonics HandbookOptical System Design: Keeping the Coatings in Mind: The design of optical systems should balance the coating constraints with the optical and mechanical requirements. Understanding the key properties and limitations of optical coatings enables the system designer to improve the performance of the optical system.An optical coating engineer is frequently confronted with a difficult specification for a coating. Often the difficulty in the specification results from the particular form of the optical system. If...Photonics HandbookLens Aberrations: Avoiding Defects in Imagery: A perfect lens can produce a perfect image. But seven primary lens aberrations can blur or distort the image instead, and they should be considered when creating an optical system.A lens collects light from a point on an object and focuses it to a corresponding conjugate point on an image.
