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.

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.

Camera Sensor Module

The VRmTS-20 from VRmagic (Mannheim, Germany) is an external sensor module for the D3 intelligent camera platform. With its compact dimensions of 26 x 26 mm and the flexible cable connection to the camera base unit, the module is particularly suitable for applications with limited or angled space. The sensor module is available as OEM version and as COB S-mount M12 version with different lenses and filter glasses.

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.

Quantitative Analysis of Failure Mode in Adhesively Bonded Test Specimens

A fluorescence visualization technique is used. Langley Research Center, Hampton, Virginia After adhesively bonded mechanical test specimens have been tested to failure, the failure mode must be interpreted and quantified. Areas of the adherent that are bare (no residual adhesive remains) have undergone adhesive failure. The remainder of the surface has undergone cohesive failure. The ability to distinguish and accurately quantify the relative amounts of cohesive and adhesive failure on a failed bonding surface is of tremendous importance in the field of mechanical testing, and for the development of bonded assemblies. Some adhesives (and adherents) are fluorescent, meaning they re-emit light at a different wavelength after being irradiated by some lighting source. This property allows for quantitative analysis of the adhesive failure mode (adhesive and cohesive). A digital image of the fluorescing adhesive or adherent can be analyzed and quantified using publicly available software to determine the relative areas of exposed and covered adherent surface.
