Portable Laser Scanner

Hexagon Manufacturing Intelligence (North Kingstown, RI) has announced the Leica Absolute Scanner LAS-XL, a new ultralarge scale portable laser scanner. Designed for industries and applications where both speed of measurement and metrology-level accuracy are necessary, the expanded measurement field and point acquisition rate of the LAS-XL means large parts and surfaces can be fully digitized in far less time than ever before.

Operating on the same flying-dot scanning technology as the Leica Absolute Scanner LAS, the LAS-XL benefits from a scan-line width of up to 600 millimeters (24 inches) and a measurement stand-off distance of up to a full meter. The extreme flexibility this delivers makes the LAS-XL as ideal for mapping large blade surfaces as it is for digitizing aircraft and rail carriage interiors. Accurate to within just 150 microns, the LAS-XL is suitable for the wide range of applications for which increased measurement speed is extremely valuable.

Confocal Imaging Platform

Andor (Belfast, Northern Ireland), an Oxford Instruments company, has launched Dragonfly 200, the latest model of its highspeed confocal imaging platform. Dragonfly integrates Andor's cameras, with patented illumination technologies and optimized optical design, to produce images characterized by low noise, wide dynamic range, high resolution, and exceptional sensitivity. The Perfect Illumination Delivery™ system (Borealis) used for confocal and widefield imaging provides exceptional stability, uniformity, and spectral range, which enables imaging in the NIR region, where natural autofluorescence of the sample is dramatically reduced.

Up to twenty times faster than conventional confocal microscopes, Dragonfly also boasts superior spatial and temporal resolution, often revealing previously undetected information in microscopic specimens. It also comes with enhancements to the included Fusion image capture software. For super-resolution, the novel SRRF-Stream technique, recently introduced to the iXon EMCCD camera range, can enhance resolution down to 50nm at live-cell frame rates.

Industrial Video Camera

IO Industries (London, Ontario, Canada) has introduced new CMV50000 CMOS image sensors to its line of Flare™ industrial video cameras. The sensors feature high pixel counts, producing images with a 7920 × 6004 resolution with frame rates up to 30 frames per second. Multiple region of interest settings (up to 10 windows) allow lower-resolution output formats at much higher frame rates. This flexibility makes the Flare series effective in applications including automated optical inspection systems, space launch imaging, wide area surveillance and more.

The sensors used in the Flare 48MP camera feature pipelined global shutter technology, which allows the sensor to expose a frame during readout of the previous frame. The global electronic shutter exposes each pixel in the frame at the same time, as opposed to rolling shutter designs, which sequentially expose rows of pixels.

Thermally Stable Laser Module

This IMM single mode laser diode module from Electro Optical Components Inc. (Santa Rosa, CA) is cooled solely using a passive system — no TEC (thermoelectric cooler) is required. The fiber-coupled single mode module can be used wherever a high degree of temperature stability and robustness is required but space and power supply are limited. Wavelengths include: 450 nm, 515 nm, 635 nm, 640 nm, 655 nm, 660 nm, 785 nm, 830 nm and 850 nm. Applications include: measurement technology, medical, engineering, research, and surveying.

XRF Coating Measurement System

Bowman (Schaumburg, IL), has introduced its P Series, benchtop XRF coating measurement instrument. It simultaneously identifies elements Al13 through U92 on the periodic table in each of up to 5 coating layers, with high precision and speed. Standard system configurations include a four-position collimator assembly, variable focus camera for applications with recessed areas, extended-life micro-focus X-ray tube, and solid-state PIN detector. The detector has well-defined element peaks, eliminating the need for secondary filters. Minimal peak position drift assures high stability over time and extends the interval between recalibrations.

The intimate proximity of the X-ray tube and detector produces more than three times the photon counts of conventional XRF equipment, and in a shorter measurement time. The extended programmable X-Y axis, suits it for measuring small features, or parts such as fasteners, connectors, and PCBs. Table size is 25” × 25”; travel is 10” × 10”.

Laser Power/Energy Meter

MKS Instruments (San Francisco, CA) has announced the Ophir® Centauri, a compact, portable laser power/energy meter for precise measurements of laser performance over time. It features a large, full-color, seven-inch touch-screen for visual review of data using graphical display formats, such as Digital with Bargraph, Pulse Chart, and Real Time Statistics Displays. Advanced math functions include Density, Scale Factor, and Normalize Against Baseline. Available in single and dual-channel versions, the Centauri is compatible with all standard Ophir thermal, photodiode, and pyroelectric sensors, including the BeamTrack power/position/size sensors. The dual channel option supports split and merged graphical displays. Every power and energy point can be logged at up to 10kHz. The Centauri's math functions can be mixed together and the results displayed graphically and logged.

Outputs include USB and RS232 for real-time integration into larger systems and USB Flash Drive output for nearly unlimited data storage. A TTL output can be used in conjunction with Pass/Fail limits to inform an outside controller when the source is out of bounds.
