Laser Welding System

The new Coherent (Santa Clara, CA) ExactWeld 230 is a turnkey solution for automated, precision laser welding of metal parts. It includes a 200W (400W optional) fiber laser, part clamping, up to four-axis (x, y, z, c), user friendly software, an optional vision system, and factory automation capabilities (Industry 4.0/IIoT ready). These features combine to maximize weld quality, and increase production yields, process consistency and operator productivity.

ExactWeld 230 also incorporates Coherent’s innovative SmartWeld™ technology for producing complex “beam wobble” patterns, including circular and zigzag paths. SmartWeld™ enables bridging of larger gaps, which relaxes tolerances, increases process flexibility, and delivers welds with higher quality and reproducibility.

24-Lane Rugged Transceiver

Reflex Photonics (Kirkland, QC, Canada) announced that its LightCONEX™ LC 150G (12TRX) blind mate optical interconnect will power a new generation of 3U form factor VPX cards developed by Interface Concept. The LightCONEX LC 150G is a full-duplex active blind-mate optical interconnect with 24-lane transceivers. It provides bandwidth in excess of 150 Gbps. Based on the OpenVPX™ standards, the LightCONEX frees up critical board space by integrating the optical transceiver into the board edge connector.

The compact 150G full-duplex (12+12) 12.5 Gbps/lane LightABLE™ LL optical transceivers are incorporated to the LightCONEX™ interconnect as per the VITA 66.5 forthcoming standard. The backplane connector, also part of the LightCONEX solution, has a floating head mechanism that ensures optimal optical mating meeting VITA 66.0 requirements.

3D Scanner

Exact Metrology (Cincinnati, OH) announces its Artec LEO 3D scanner, the first scanner to offer onboard automatic processing with an integrated touch panel viewer. The scanner has a 3D reconstruction rate of 80 frames per second, and features data acquisition up to 4 million points/second, with a working range of .35-1.2 m. The 3D resolution on this scanner is up to .5 mm and 3D point accuracy up to .1mm. State-of-the-art technologies including the NVIDIA® Jetson™ platform, which is the scanner’s internal computer, featuring Quad-core ARM® Cortex® -A57 MPCore CPU and NVIDIA Maxwell™ 1 TFLOPS GPU with 256 NVIDIA® CUDA® Cores; a built-in 9 DoF inertial system- accelerometer, gyro and compass.

LEO has the ability to scan in sunlight, as well as capture dark and shiny objects. The texture resolution is 2.3 mp. This handheld scanner is equipped with a 4'' LCD screen to capture images of the data. The 3D light source is provided by state-of-the-art VCSEL (Vertical-Cavity Surface-Emitting Laser) technology. There are 2 cameras on this scanner. One is a range camera for 3D geometry and another is a color camera. The color camera captures color texture data.

Fiber Laser System

Prima Power Laserdyne (Champlin, MN) has reintroduced the 890 LASERDYNE® Multi-Axis Laser Processing System. This is an all-new LASERDYNE 890 system with a powerful, efficient fiber laser, the latest highly flexible BeamDirector®, and the S94P control loaded with a full portfolio of Smart Techniques™ operating capabilities. Featuring a large 96 × 72 × 36 inch (2440 × 1830 ×400 mm) work envelope for the X, Y, and Z axes – along with the latest BeamDirector and a complete flexible five-axis work envelope – the modern LASERDYNE 890 is designed for large part welding, drilling and cutting processes.

The QCW fiber laser delivers maximum peak power equal to 10 times that of average power. The S94P controller delivers precise and controlled pulses for consistent and reliable manufacturing processing. Fiber lasers are more efficient and provide significant cost savings over CO2 and Nd:YAG lasers. The Prima Power Laserdyne BeamDirector features direct drive design, optical encoders for high accuracy (+/- 15 arc-second) and repeatable, high assist gas pressure and flow, and adjustable mirrors for easy and accurate beam alignment. Rotary (C axis) motion is 900 degrees about the vertical axis while tilt (D axis) travel is ±150 degrees about the horizontal axis

Femtosecond Laser

LXR 100, the first femtosecond laser from Luxinar (Kingston Upon Hull, UK), has been added to the company’s product portfolio, meaning Luxinar now produces ultrashort pulse lasers in addition to sealed CO2 laser sources. The LXR 100 is capable of a large dynamic range of average powers, pulse energies and operating modes. The pulse width is between 900 ± 100fs, with a pulse repetition frequency between single shot and 40 MHz, and a maximum rated pulse energy of 100μJ. Burst mode and pulse on demand are available. The controller has been developed to ensure the necessary functionality is available whilst ensuring high precision can be achieved.

The extremely short pulse width of the laser virtually eliminates heat diffusion to the surroundings of the processed region, minimizing the formation of a heat-affected zone (HAZ), and enabling ultrahigh precision micro- and nanofabrication of various components. The high peak power also enables novel modes of processing within the bulk of the material rather than restricting interaction with the material surface. Most applications for ultrafast lasers are currently found in consumer electronics, medical, automotive, research, aerospace and defence.

Programmable DC Loads

SIGLENT Technologies (Solon, OH) introduced the SDL1000X and SDL1000X-E series of programmable electronic DC Loads designed for battery, solar cell, and power supply testing. The SDL1020X/X-E models offer an input range of 150V/30A with 200W total power dissipation, while the SDL1030X/X-E’s have an input range of 150V/30A up-to 300W. The X type provide a measurement resolution of 0.1 mV/0.1 mA, whereas the economical X-E type offers 1 mV/1 mA.

All models come standard with a 3.5-inch TFT-LCD display and user-friendly interface. As part of this functionality, operators can use the Program function (maximum 50 groups) and List function (maximum 100 steps) to create complex discharge profiles, which can be useful in battery charging circuitry design. The SDL1000X/X-E series is equipped with additional features that include an LED-test mode (CR-LED) designed specifically for LED driver testing.

Objective Scanner

Prior Scientific (Cambridge, UK) has released the NanoScan OP400, a piezo-based objective scanner. Prior Scientific acquired Queensgate in 2018 and the NanoScan OP400 combines Prior’s expertise in delivering microscopy solutions with Queensgate’s nanopositioning technology. The OP400 is compatible with most microscopes and objective lenses, has a range of optimized settings for different objective sizes, weights, and performance needs - the user simply selects the best setting for their application.

Coupled with the Queensgate NPC-D-6110 digital controller the system is easy to use and quick to set up using standard 0-10V analog input and output. The digital control technology allows control of stage movement with variable acceleration/deceleration algorithms, which improves step settle time by reducing overshoot and prevents stage ringing. The system can be used as a standalone objective positioner or can be interfaced with other Prior products via Prior’s ProScanTMIII controller.
