Transparent ceramics have recently acquired a high degree of interest and notoriety. Basic applications include lasers and cutting tools, transparent armor windows, night vision devices (NVD), and nose cones for heat seeking missiles. Currently available infrared (IR) transparent materials typically exhibit a trade-off between optical ...
Large laser elements made from transparent ceramics can be produced at a relatively low cost. These components are free of internal stress or intrinsic birefringence, and allow relatively large doping levels or optimized custom-designed doping profiles. This makes ceramic laser elements particularly important for high-energy lasers.
Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.
Lumicera is a transparent ceramic developed by Murata Manufacturing Co., Ltd.. Murata Manufacturing first developed transparent polycrystalline ceramics in February 2001. This polycrystalline ceramic is a type of dielectric resonator material commonly used in microwaves and millimeter waves.
It can be made nearly transparent (15–20% loss in a typical cooktop) for radiation in the infrared wavelengths. In the visible range glass-ceramics can be transparent, translucent or opaque and even colored by coloring agents. However, glass-ceramic is not totally unbreakable.
Police in have revealed tragic new details behind the mysterious death of a 26-year-old Polish newlywed two years after she was found on the streets of Miami.
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with waves that are just longer than those of red light (the longest waves in the visible spectrum ), so IR is invisible to the human eye.
The search for missing hiker Susan Lane-Fournier, 61, took a tragic turn after her body was found over the weekend in Welches, Oregon, an unincorporated community at the base of Mount Hood.
