PRODUCT UPDATE LASER SYSTEMS
FS200M×2 Farsoon has introduced the FS200M×2 platform as a new addition to its medium- sized metal LPBF portfolio. The system is equipped with a versatile build volume of 425 x 230 x 300mm and a powerful dual 500W laser configuration. It is ideal for medium- to-high volume metal series production and prototypes, with fast manufacturing turn-over rates, versatility and impressive ROI. Equipped with powerful dual-laser
scanning technology and advanced calibration algorithms, the FS200M×2
TEST AND MEASUREMENT SmartSense+
Coherent has introduced the SmartSense+ process monitoring system, which enables improved results and better reproducibility in welding, cutting, marking, engraving and cleaning applications, while providing traceability and documentation data. This opto-mechanical accessory
incorporates optical detectors and (optionally) acoustic sensors, and includes all the required data acquisition and signal processing electronics and software. It is readily integrated into Coherent’s ExactCut, ExactWeld, StarCut, StarFiber, MPS, UW and PowerLine series laser systems, while also being compatible with several other Coherent fibre, diode and ultrashort pulse lasers. The SmartSense+ captures back-reflected laser light, plus light emitted by the process
BeamPeek
MKS Instruments has launched the Ophir BeamPeek, an integrated beam analysis and power measurement system for fast, accurate, real-time measurement of lasers in additive manufacturing chambers. The system provides simultaneous beam profiling, focal spot analysis, and power measurement in just three seconds. The system is a compact, ruggedised,
high-power laser measurement tool that measures powers up to 1kW for two minutes for both green (532nm) and NIR wavelengths (1,030 to 1,080nm). The active components (electronics, optics, camera and power meter) are located in a sheltered chamber whose temperature rise is not more than 2.5˚C per minute at 1kW. The system includes an innovative beam dump designed as a replaceable tray that eliminates the need to waste time letting the system cool down. As the main beam enters the system, it encounters a beam sampler that diverts
approximately 4 per cent of the laser’s power to the thermal sensor; the remaining 96 per cent is captured by the beam dump for faster cooling. This allows measurements to be repeated immediately, allowing for sustained work cycles. There is no need for water or fan cooling as the replaceable tray eliminates downtime between measurement sessions. The system is ideal for field service testing of additive manufacturing chamber powder beds.

offers exceptional build rates. The system offers precise tailoring of its processing parameters and is able to integrate multiple scanning strategies of different layer thickness in a single build, according to the application’s needs. The FS200M×2 is equipped with an
integrated, two-stage filter module, featuring a powerful back-flush function to ensure filter life and repeatable part quality. In addition, in-chamber cameras are used to monitor and record data for each layer during builds.

OPTICS
itself. This light is split into its visible, laser wavelength and near-infrared components, and sent to three separate detectors. Together, these signals deliver detailed information about the absorption of the laser light, the characteristics of the plasma (ionised plume) created
by the laser process, and the surface temperature of the part. The option for detecting acoustic signals, using piezoelectric contact sensors and microphones, enables acquisition of an even more
comprehensive process fingerprint, such as heat cracking in a joint during, or even
after, the welding process. The use of high data acquisition rates enables the SmartSense+ to work with both high- and lower-power continuous-wave and pulsed lasers.

Linos F-Theta Ronar
Excelitas Technologies has launched its Linos F-Theta Ronar 251mm Telecentric Lenses for laser material processing applications, including drilling, welding, cutting, structuring and additive manufacturing. Optimised for back reflection with an
entrance aperture up to 20mm, the new lenses, intended for 1,030 to 1,080nm wavelengths, feature a large, effective focal length with low spot variation. A low- absorption coating and interchangeable, coated protective glass made of fused silica equip the new lenses for ultrashort laser pulses and high-power applications up to 10kW. The product utilises a standard M85x1 connecting thread. It is dust-tight on the output side, including protective glass for extended lens life and cost savings. The 251mm telecentric lens product
joins Excelitas’ Linos F-Theta-Ronar family of lenses, which all have two main characteristics: when a beam is deflected by a scanning mirror in front of a lens, the scanned distance is proportional to the scanning angle; and the focus position over the entire scan field is always in the same plane. These lenses feature innovative optical designs, coupled with the highest- grade materials and precision manufacturing to ensure ultra-precise performance for laser material processing systems.
