Lasercut Inc. (Branford, CT; has developed the Lasit FlexyMark, a 20-watt maintenance-free air-cooled, fiber laser marking system. This system is used for marking metals and plastics with reliability exceeding 100,000 hours. This marking system is available as an OEM component or a Class One Enclosed turnkey system, and provides reduced operating costs and high throughput. It is compact, high speed, modular, flexible, and is available with a full range of ancillary equipment such as XY tables, rotary attachments, rotary indexers, automatic Z axis, on-the-fly marking capability, and conveyors. This fiber laser system allows for easy integration for in-line production by interfacing to an existing PLC system.

Goggle accessories

New from LASERVISION GmbH (Fuerth, Germany;, anti-fog inserts and polycarbonate filters for laser safety goggles have been introduced. The anti-fog inserts are plastic sheets coated with nanoparticles that absorb humidity and avoid saturation of the air with water vapor. With these easy-to-use inserts, fogging of the goggle is impossible. In addition to the anti-fog inserts, a polycarbonate filter has also been developed. These absorbing polycarbonate filters are more economic and light-weight as well. Goggles with this polycarbonate filter are available with curved lenses, which open a wider field of view. In addition to the polycarbonate filter, absorbing mineral glass filters and mineral glass filters with coatings on have also been developed.

Coding system

The MACSA K-1000, a laser coding system from ID Technology (Fort Worth, TX; has recently been launched. The K-1000 laser coder is compact and has an adjustable marking head. This system is ideal for clear messages that must be delivered at minimal operating costs, and marks easily on labels, cardboard, PET, glass, or wood. This user friendly laser can be controlled via hand-held terminal, remote touch screen, or from a remote PC.

Laser weld process monitor

The MML-11 A, from Miyachi Unitek Corporation (Monrovia, CA; records time and magnitude data on actual incident and reflected IR energy in real-time. This laser weld process monitor provides process control for aerospace, automotive, computer peripheral, and other specialty devices. For each weld pulse, the MML-100 A measures actual incident instantaneous laser power delivered to the workpiece as well as the reflected power in real time. The material threshold is evident, and can also be correlated to weld penetration and other weld quality characteristics for many materials and weldment geometries.

Glass optical components

New from MOULDED OPTICS GmbH (Schoffengrund, Germany; is a complete high-performance line of standard and custom precision molded glass optical components in sizes from 2mm to 100mm, coated or uncoated, including: aspheric, bubble, cylindrical, fly’s eye array, free form, Fresnel, half-ball, integrator play and wedge, light pipe and tunnel, multi-array, plano, prismatic, relay and spherical lenses; aspheric, concave first surface, flat, spherical and free form mirrors; dispersing, dove, folding, penta, porro, roof, and wedge prisms; ellipsoidal, multi-facetted, parabolic and prismatic reflectors; flat, free form, and spherical windows.

Repair system

New from Electro Scientific Industries (Portland, OR;, a dual-beam infrared laser link-processing system for DRAM and NAND Flash memory applications, Model 9850, a laser repair system, has been introduced. Utilizing two beams from a single laser, the new Model 9850 system is able to process two links at the same time, with potential throughput of up to 95 percent over single-beam systems. The system is designed to handle 300mm wafers, with typical monthly capacity of up to 4000 wafers.

Diode-pumped Q-switched lasers

The NL200 series nanosecond diode-pumped Q-switched NL200 series lasers, developed by EKSPLA (Lithuania; offer 2 mJ per pulse at 1000 Hz, and in addition a version providing 0.7 mJ per pulse at 2500 Hz is also available. The end-pumped design ensures compact size of this nanosecond laser. Featuring short pulse duration, variable repetition rate, and external TTL triggering, nanosecond diode-pumped NL200 series lasers are cost effective and useful for applications such as pulsed laser deposition, ablation through mark, or intravolume marking of transparent materials.

Gas-saver regulator

CONCOA (Virginia Beach, VA; released a new gas-saver regulator that eliminates surge and lowers shielding gas costs. Designed for high-pressure/liquid cylinder or pipeline use, the Gas-Saver regulator enables the user to remove the key after the appropriate flow rate is set, in order to control process quality. The Gas-Saver technology couples a non-compensated flowmeter to an adjustable regulator. The flowmeter accurately displays the gas flow rate, even when the regulator is adjusted to as low as 3 or 4 psi. This tamper-resistant feature reduces not only excess gas usage, but also weld defects.

Commercial grade optics

Anchor Optics Surplus (Barrington, NJ; introduced a newly expanded line of commercial grade optics. They have standard designs and are suitable for production, prototyping applications, and volume users as well as OEM use. The new product lines are as follows: PCX lenses, RA prisms, mirrors, and windows. To accompany the new commercial grade optics are optical tools and bench equipment, diffusers, fiber optics, microscopes, magnifiers, magnets, spectral analysis, books, and educational optics.

Label cutting/marking

New from Rofin-Baasel UK (United Kingdom;, the Label Marker E has been developed. An integrated system for high-speed marking and cutting of labels, this method of marking utilizes full parametric control enabling the marking of graphics and machine-readable symbols, while ensuring maximum flexibility. The design of the machine ensures a small footprint for minimum required floor space and maximum operating comfort due to process visualization via HMI and touch screen. Manufactured to IP 54 standards, the Label Marker E can be operated in tough industrial environments.

Cutting/scanning systems

New from Robotic Production Technology (Auburn Hills, MI;, the FLACS RT-C-series Flexible Laser Cutting System with second generation RoboCut A600 laser robot has been introduced. The laser system incorporates support structure, guarding, and part positioning equipment, as well as robot, laser, and ventilation support equipment, into a pre-engineered package. The system includes a second generation RoboCut robot, which is the first robot with integrated 100- to 1000-watt CO2 lasers and power control. The laser system incorporated in the A600 model is 20 percent lighter and beam control components are reduced by 50 percent, resulting in greatly improved reliability and durability.
