High-speed laser cutting
Cincinnati (Cincinnati, OH; has added two models to is family of linear-motor-drive laser cutting centers. The CL-840 and CL-825 enable users to tailor machine performance to specific cutting requirements for optimal processing efficiency. Both models feature Fanuc fast-axial flow resonators-4000W continuous power for the CL-840 and 2500W for the CL-825. Each machine is available in 5 x 10 and 6 x 12 ft cutting table sizes and comes standard with full guarding. Dual-pallet quick-change design enables one pallet to be unloaded/reloaded while the second is being processed.

The CL-840 processes mild steel up to 1 inch and stainless steel and aluminum up to ½ inch, while the CL-825 cuts mild steel up to 5/8 inch and stainless and aluminum to ¼ inch. An enhanced beam system with distributed purge air enables high-precision and high-productivity cutting both thick and thin material.


User friendliness is the focus of the new version of TRUMFP’s (Farmington, CT; TruTops software, and improvements include a new user interface, increased productivity through Product Data Management, a more efficient nesting processor, and the elimination of redundant data management. The software has been created specifically for the company’s fabricating equipment, including 2D laser machines, punching machines, and press brakes.

Wire marker

The Nova 880 is the highest-speed wire marker developed to date by Spectrum Technologies (Bridgend, UK; The product uses a high-power UV laser and optical system based on the company’s proprietary Longbow UV solid-state laser to achieve marking speeds up to double those of the company’s current top-of-the-range marker. The Nova 880 is available as either a manual system or with fully automated wire handling for selecting and loading wires. The new auto-select and load (ASL) system doubles the number of wires that can be handled automatically from the previous 16 to 32 wires or cables. Wire loading times also have been reduced.

Focused spot accessory

Ophir-Spiricon (Logan, UT; announces a new accessory for use with its Laser Beam Analyzer profiler software that enables direct measurement of many laser beams at and near the focus. The accessory is retrofittable to most of the company’s existing systems. The device attaches to the front of all of the existing “C” mount CCD cameras and attenuates the beam so that when the focused spot reaches the focal plane of the camera, it is attenuated enough that the energy density can be successfully imaged. The beam profile and quantitative ISO-compliant calculations can then be displayed in real time on the user’s computer display.

PCB fabrication

The Paladin Compact 355-4000 from Coherent (Santa Clara, CA; is a solid-state, UV laser that delivers 4 watts of quasi-CW output (at 355 nm) in a small package. Specifically designed for OEMs, the laser can be either air-cooled or water-cooled, and its beam parameters are identical to the larger-sized 4W Paladin model. The new unit requires only a single, long-lived pump diode (the main consumable in this type of laser), rather than two pump diodes. According to the company, this unit excels at applications in the Laser Direct Imaging of high-density printed circuit boards, as well as semiconductor wafer inspection.

Field replacement optics

Field replacement CO2 laser optics that meet OEM specifications for low-power lasers used in cutting, marking, and de-gating plastics are available from Laser Research Optics (Providence, RI; The lenses and mirrors meet OEM and ISO-10110 specifications for optical elements. Optimized for use at 10.6 µm, they are compatible with Amada, Coherent, Continuum, Cincinnati, Epilog, Lambda Physik, Mazak, Synrad, Universal Laser Systems, and similar lasers.
