Color Dome

The ESD-380DR high-speed color dome from ELMO USA Corp. (Plainview, NY) provides 360° continuous pan rotation at a travel speed from 5° to 400°/second. It operates from presets with 180° auto turnaround. The ESD-380DR features tilt travel from -10° to 190°, and 256 programmable preset pinpoint target areas. Pan and tilt speed automatically adjust in proportion to the depth of zoom. The color dome includes an IP66-rated weather-resistant outdoor housing, and a day/night model that captures image details in glaring sunshine or darkness. Minimum illumination is 0.01lux. CCD color cameras with DSP circuitry provide resolution of 470 TVL images, and feature 23× optical zoom with 12× programmable zoom. A 24-position privacy zone-masking protects against intrusive monitoring. Other features include digital flip, auto/manual focus, auto iris, auto/manual white balance, auto/manual focus, backlight compensation, eight programmable alarm inputs, and an OSD display for setup.

Laser Ultrasonic Receiver

Lasson Technologies (Culver City, CA) has released the AIR-1550-TWM laser ultrasonic receiver for component inspection and nondestructive evaluation of material properties. Part of the AIR family of receivers, the AIR-1550-TWM operates at a wavelength of 1,550 nm. AIR receivers are based on a common platform with a modular design, offer fiber coupling to a selection of sensor heads, and use a chassis designed for benchtop use or compatibility with the standard 19" rack-mount systems. Common measurement applications include material thickness, weld inspection and dimensioning, inspection of electronic packages, and general defect location and characterization.

Laser Doppler Vibrometer

MetroLaser (Irvine, CA) has announced the VibroMet 500V single-beam laser Doppler vibrometer that features a sensitivity range of 2 microns/sec, and a vibration velocity measurement range of 1 meter/sec. The laser is collimated, so there is no need to adjust a focusing lens. Its solid-state laser diode ensures the system receives signals at distances of up to 5 meters. The system has a visible red laser beam for point and measure operation. The VibroMet 500V is suitable for quality assurance, product optimization, and other applications that require measuring vibration without touching the object being measured. Common measurement applications include turbine blades for aircraft and power generators, automobile engines, body parts and mufflers, computer disk drives and storage devices, and optical and laser systems.

Shortwave Infrared Camera

Sensors Unlimited, Goodrich Corp. (Princeton, NJ) has announced the SU640SDWH-1.7RT high-frame-rate, high-resolution, shortwave infrared (SWIR) camera. The indium gallium arsenide (InGaAs) camera has regions of interest (ROI) windowing capabilities with high-sensitivity SWIR spectral response from 900 nm to 1,700 nm. The 640 × 512 pixel focal plane array on a 25-micron pitch captures full-size images at 109 frames per second, or can image smaller regions of interest at over 15,000 frames per second with 100% fill factor.

Multiplexer

LightSmyth Technologies (Eugene, OR) offers an integrated, single-mode-compatible, coarse WDM (CWDM) multiplexer based on the company’s nanophotonic filtering technology. The unit is passively athermal and polarization insensitive to 0.2 dB. It is based on the silica-on-silicon planar waveguide format, and requires chips of only 1 square centimeter. It uses the Deep UV photolithographic patterning tools used in electronics. The multiplexer’s diffractive nanophotonic filtering engine combines the integration capabilities of gratings with the functionality of thin-film filters.

The Air Bearing Advantage in High-Precision Positioning

All moving objects possess six degrees of freedom — three linear and three rotary. The task of a linear motion guideway is to eliminate, as closely as possible, five of these degrees of freedom, leaving a single rotary or linear axis of motion. Air bearings are the purest and highest-performance means of defining linear or rotary motion, and have substantial advantages over conventional mechanical guideways. These advantages become more pronounced as the desired resolution increases, and many aspects of high-precision positioning are uniquely enhanced when air bearing guideways are chosen.
