Circular Variable ND Filters

Reynard Corporation (San Clemente, CA) recently announced the complete customization of their Circular Variable Neutral Density (CVND) Filters. This technology is best used in high quality optical systems to change the intensity of light from 100% to less than 0.1%. As the filter rotates, the beam intensity is customized due to the density variation of a gradient metallic coating around the filter. Used from the UV to the far infrared, density neutrality can be achieved for narrow band applications, such as lasers, to wide band applications, such as the spectrum of white light.

High-Shock Sensors

Diversified Technical Systems (Seal Beach, CA) has released the 6DX PRO, a high-shock sensor with six degrees of freedom. The three angular rate sensors (18000 or 50000 deg/sec) deliver position data, while the three accelerometers (2000 or 20000 g) are rated for high-impact environments. The 19 × 19 × 14.5-mm enclosure weighs 12 grams. The 6DX PRO is also sealed, IP67 rated, and compliant with NHTSA, FAA, ISO 6487, and SAE J211 practices.

NASA Spinoff: NASA’s UV Radiation Research Keeps Sun Worshipers Safe

Studying radiation effects on spacecraft led to a personal Sun exposure monitor. To understand the Sun’s impacts on Earth, NASA initiated the Living with a Star program in 2001, and began developing a key research satellite: the Solar Dynamics Observatory (SDO). One of the instruments created for the SDO was the Extreme Ultraviolet Variability Experiment (EVE), tasked with measuring extreme ultraviolet (UV) radiation, which plays a key role in atmospheric heating and satellite drag. In 2005, Goddard Space Flight Center scientist Shahid Aslam joined other researchers in developing EVE.
