Abstract
  HfO2 thin films have gained much significance in recent years as a promising dielectric material for semiconductor electronics added to their wide applications in the field of optical filters as a high index material. The resistance of HfO2 films to impurity diffusion and intermixing at the interface ...  Read More

Single point diamond turning of silicon for flat X-rays mirrors

Neha Khatri; Rohit Sharma; Vinod Mishra; Harry Garg; Vinod Karar

Volume 2, Issue 7 , 2017, , Pages 425-427

https://doi.org/10.5185/amp.2017/704

Abstract
  Silicon Mirrors are essential components for guiding the X-Ray beam and focusing it to a particular location. Due to lower X-ray wavelength, these mirrors require super smooth surface finish to avoid the strong scattering from surface. Single Point Diamond Turning is used to examine the fabrication possibility ...  Read More

Surface finish and subsurface damage distribution during diamond turning of silicon

Rohit Sharma; Neha Khatri; Vinod Mishra; Harry Garg; Vinod Karar

Volume 2, Issue 7 , 2017, , Pages 433-435

https://doi.org/10.5185/amp.2017/706

Abstract
  Subsurface Damage (SSD), which is introduced to optical materials by diamond turning processes, affects the performance in optical, laser and infrared applications. For optical applications, SSD can be the source of component instability (e.g., surface stress) and flaw. The objective of the present study ...  Read More

Design and fabrication of multilayer dichroic beam splitter

Vinod Karar; Amit L Sharma

Volume 2, Issue 6 , 2017, , Pages 398-401

https://doi.org/10.5185/amp.2017/610

Abstract
  Beam splitters are primarily used for applications like avionic displays, optical storage, fluorescence applications, optical interferometry, semiconductor instrumentation where some of the information needs to be reflected as well as transmitted. They operate on the principle of light being ...  Read More
