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.

Laser Radiation Detector Screens

The path of invisible laser radiation can be verified using detector cards from Laser Components (Hudson, NH). These cards are ready for immediate application and do not have to be activated or optically charged. The cards for wavelengths from 1.5m to 5m and 5m to 20m can localize the beam path of Hol:YAG, Er:YAG, and CO2 lasers, for example.

Deep UV Luminescence Spectrophotometer

McPherson (Chelmsford, MA) has announced a new vacuum ultraviolet universal spectrophotometer, an optical test system optimized for emitting samples like phosphors or photo- and electro-luminescent crystals. It can measure reflectance, transmission and fluorescence emission over its complete working range, 120 nanometers to 2.2 microns. The sample chamber includes high efficiency toroidal optics for focused excitation and sensitive detection. It can operate purged or under vacuum and can interface to commercial cryogenic and heated sample mounts.

Samarium Oxide Glaze

Developed for high-energy pulsed Q-switching infrared laser applications, a new, high-absorption samarium oxide glaze from Morgan Advanced Materials (Windsor, UK) means it is now able to offer three grades of glaze for laser systems. The samarium glaze absorbs radiation at the Nd-YAG lasing wavelength of 1064nm, and its further transitions near 940nm, 1120nm, 1320nm and 1440nm. A significant amount of fluorescent radiation at the lasing wavelength escapes laterally from the laser rod into the surrounding pumping cavity. Absorbing this radiation prevents it from being reflected back into the laser rod, which would in turn stimulate decay from the upper laser transition level, thereby limiting the number of excited ions which can occupy that level.

Shock-Sensing Apparatus

This apparatus enables easy and reliable shock detection and localization in high-speed inlets of aerospace vehicles. John H. Glenn Research Center, Cleveland, Ohio Acompact shock-sensing device, which employs an innovative light sheet generator, has been created. The device may be used either as a solo aerodynamic shock detector or in combination with a scanning mode shock sensor. This permits easy detection and tracking of unstable and traveling shocks in supersonic inlets.
