To maximize the performance of a coating for a given application, a better understanding of coating design and deposition technique is a must.

STEFAAN VANDENDRIESSCHE, EDMUND OPTICS INC.

Optical coating design and performance are critical for a growing number of applications in fields as diverse as biomedicine and astronomy. Coatings can perform a variety of functions, from imparting high reflectivity on telescope mirrors, to controlling polarization and removing unwanted reflections. As laser usage continues to increase globally, the use of laser-specific optical coatings increases in tandem. The ongoing improvements in laser power, pulse length and wavelengths have resulted in new coating requirements, spurring the development of novel coating technologies. TECHSPEC...Read full article

    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    optical coatings
    Optical coatings are thin layers of materials applied to optical components, such as lenses, mirrors, filters, and prisms, to modify their reflective and transmissive properties. These coatings are designed to enhance the performance of optical systems by controlling the way light interacts with the surfaces of the components. The primary purposes of optical coatings include: Antireflection coating: This type of coating is designed to reduce reflections from the surfaces of optical...
    ion-beam sputtering
    Ion-beam sputtering (IBS) is a physical vapor deposition (PVD) technique used for depositing thin films onto substrates. It involves bombarding a target material with a beam of energetic ions, typically inert gases such as argon, to dislodge atoms from the target surface. These dislodged atoms are then deposited onto a substrate, forming a thin film. Here is a breakdown of the process: Ion bombardment: In ion-beam sputtering, ions are accelerated to high energies and directed towards a...
