2 Image Quality A good image must look sharp, brilliant, and must be stable. Sharpness means that the image has well-defined black and white edges, and that even fine details 23 24 Advanced Optics Using Aspherical Elements are resolved with good contrast. The image must look “fresh” and brilliant, and the colors should be undisturbed. We accept an image as “stable” if we observe no color shading when moving the object slightly out of the plane of best focus. Our eye would react very negatively if a slightly defocused image gets colored “comatic” errors.

There is a principal trend that higher density materials have higher refractive indices and dispersion values (Fig. 6). There is also a large price variation for optical materials. 20 Euro/kg, are at the low-cost side. Together with injection-molding techniques, one obtains lens costs more in the cent than in the Euro region. Glass aspheres for consumer applications produced by precision molding cost several Euros. Aspheres of larger diameter for industrial optics cost more than 100 Euro per lens.

Polymers in general have low transmission in the UV. Additionally, they show solarization effects at lower wavelengths, causing further transmission losses due to degradation effects during light exposure. , YAG, Yttria), high transmission values are obtained. In the UV region below 250 nm, fused silica, phosphate glasses, CaF or LuAG crystals, as well as Spinel optoceramics can be used. In the three IR bands (1–14 μm), for example, germanate glasses, chalcogenide glasses, ZnS, ZnSe crystals, or optoceramics such as AlON, YAG, yttria, or Spinel show advantageous properties (Fig.
