Classical Optical Filters,h range at normal incidence. Hence, each glass optical element (lenses, waveplates, etc.) working at transmission mode is responsible for at least 8% of the losses in transmitted power. The situation is even worse for optical elements made of higher refractive index materials. Therefore, the total t

Omnidirectional Dielectric Reflectors,disadvantages despite very low losses, like a limited wavelength range of reflection bands and the dependence of the spectral position of the reflection band on the angle of incidence. However, very recently it was found (), that by using different design rules, it is possible to create a multila

Omnidirectional Short-Pass Filters,es. These applications include deep-UV focal-plane arrays for military applications, electrical spark imaging, water purification, blood chemistry analysis, and the chemical evaluation of foods, pollutants, and gases. As the wavelength of light becomes shorter in the ultraviolet range, existing opti

Classical Optical Filters,can (and usually does) reach the focal plane, which leads to the degradation of optical system performance. To solve these problems, . are used. Antireflection coating is usually understood to be the coating of the optical surface minimizes the reflection from the surface at some angles of incidence over a specified wavelength range.

Omnidirectional Dielectric Reflectors,multilayer dielectric reflectors. This chapter is devoted to the discussion of such a multilayer structure. To understand how such a structure works, it will be useful to understand Bloch waves and band structures of periodic multilayer media.
