Mark verification
IMP (Intelligent Mark Positioning) by Virtek Laser Systems (Ontario, Canada; www.virtek.ca) verifies positioning and orientation of a part prior to marking and is capable of accepting or rejecting marking of the part. Part verification, mark content, and laser control are accomplished through integrated software. The company says the one-time job setup can be transferred to other FOBA lasers to offer machine-to-machine consistency. Reportedly, typical changeover time also can be reduced by 40 percent or better when compared to laser systems without IMP.

Blackened optics

Edge-blackened optics from Edmund Optics (Barrington, NJ; www.edmundoptics.com) are designed to increase contrast and reduce noise in imaging and electro-optical systems The blackened edges prevent light from exiting a mounted optic, reflecting off the metal fixturing and being re-imaged through the optical assembly. According to the company, offering the edge blackening as a standard option eliminates a labor-intensive step in integrating the optics into OEM assemblies.

Drilling heads

As opposed to analog drilling heads of conventional servo technology, the settling time of the digitally controlled intelliDRILL 20 series, from Scanlab AG (Puchheim, Germany; www.scanlab.de), will not keep rising linearly with the increasing pitches, but turns into a square-root-function by the digital servo control algorithms. This results in a product that is capable of 2 kHz precise positioning over short pitches (1 mm). Typically, positioning of 10mm stroke can be minimized down to 1.5 ms within a settling accuracy bandwidth of +/-3 μm (defined at approximately f = 100 mm focal distance). Other smart functionalities include remote diagnosis saving maintenance costs, real-time monitoring of detailed operational states, and integration of multiple tunings in one system.

Conversion screens

With the help of the LDT-300B and LDT-300BG models, UV radiation from 190 to 390 nm can be made visible. The screens are designed for high power levels with a damage threshold of >10kW/cm2 (CW) or >10J/cm2 (pulsed). Typical applications include working with excimer, gas, and frequency-tripled Nd:YAG lasers.

Diode lasers

The Limo(Dortmund, Germany; www.limo.de) Limo25-F200-ADL9xx and Limo32-F400-ADL9xx diode modules operate without any thermoelectric or water cooling, which results in a compact and cost-effective diode laser system that requires only a fan to provide the necessary cooling. The output power of the two fiber-coupled devices are 25 watts and 32 watts, respectively, and they operate with a maximum pulse duration of 10 minutes. They can be used in the welding of plastics and soldering.

According to the company, the almost perfect beam quality with output power up to 25 watts and pulse rep rate to beyond 1 MHz make these UV lasers ideal for micromachining of silicon and various semiconductor processing applications.

Scribing machines

Built on the ChromaDice diode-pumped solid-state (DPSS) laser platform, the Class 1-enclosed laser scribing systems from JP Sercel Associates (Manchester, NH; www.jpsalaser.com) are designed for the isolation and series interconnection of thin-film solar cells. They employ high peak power, short-pulse DPSS laser sources to remove a variety of thin films from large glass, metal, or polymer substrates. A number of wavelengths suitable for different layer materials are available, including 1064 nm, 532 nm, 355 nm, and 266 nm.

Hard-cover linear stage

The ATS115 is Aerotech’s (Pittsburgh, PA; www.aerotech.com) smallest hard cover, side-sealed stage design. The aluminum hard cover is hard-coated for scratch resistance. The side seals keep dirt and particulates out of the stage, protecting the bearing surfaces from contamination and significantly increase stage bearing life. The product uses a NEMA 23 flange-mounting interface for attachment of a wide variety of Aerotech and third-party motors. The company can provide brush, brushless, and stepper motors pre-configured and mounted directly to the stage for integration with its controls. The base mounting holes are accessible from the outside of the stage for ease of integration.
