Single Longitudinal Mode Blue-Violet Laser Diode for Data Storage
blue-violet laser diode source with a long coherence length and some level of wavelength tuning. Prior approaches, such as external cavities with diffraction gratings [1], have been used to generate single longitudinal mode tunable lasers near 405 nm. Such cavities require a very low reflectivity

affect critical dimension (CD) control and process yield, which inevitably eats away at a fab's profitability. Optics design is fundamental to a system's relative sensitivity to contamination. High-reflectivity systems, such as rear-view mirrors, must be. MICRO: Viewpoint

Ultrasonic sensors
ideal targets because of their high acoustic reflectivity. Porous targets such as felt, cloth, or foam rubber make poor targets because of their high sound-absorption properties. Liquids typically are excellent targets for ultrasonic detection because of their smooth, reflective surface. However

Security: A Four-Step Approach
to which it is applied (a rough surface can result in poor reflectivity) and also adding, say, a hologram foiling machine to the production line may have an unacceptable effect on throughput. Pilot production also provides samples with properties that are very close to the final specification

Monitoring residual and process gases in PVD processes: The importance of sensitivity How much quadrupole mass analyzer sensitivity should be required for meaningful monitoring of residual gas levels in sputter deposition processes?
monitoring of residual gas levels based on the available data and the normal residual gas background levels that have been measured during hundreds of hours of deposition in a production multichamber sputter system. Metallization film quality is monitored by measuring the reflectivity and resistivity

, electrical, and mechanical properties. Reflecton epoxy meets the demand for dense packaging and components by reflecting "good" light and keeping out unwanted light, thus enabling thinner package designs. By balancing high reflectivity with opacity, Reflecton makes it possible for design engineers

Introduction to Prisms
that is greater than a special angle of incidence called the critical angle. When light has experienced total internal reflection at a surface of glass, it is completely trapped inside the glass at that point. The efficiency of total internal reflection is so high that no coating can equal its reflectivity
