Polytec introduced the MMA-300, describing it as the world's first integrated laser Doppler vibrometry and stroboscopic video microscopy system for full-field 3-D characterization of MEMS dynamics. The MMA-300 combines the MSV-300 scanning laser vibrometer with the new PMA-300 planar motion analyser. It maps out-of-plane vibration while PMA-300 measures in-plane motion simultaneously. The analyser exploits the advantages of both techniques: the extreme accuracy, speed, and broad application of laser Doppler together with video microscopy's ability to measure in-plane motion of virtually any surface.
MSV-300 offers a measurement frequency range from near-DC to 30 MHz, including FFT and time domain processing. Whole-field vibration response is animated for specific frequencies or in the time domain. A laser vibrometer measures any vibration waveform in real time, including transient and random.
Applications include modal analysis, impulse response, settling times, resonant frequencies, Q-factors, calibration, FE model verification and reliability of MEMS, telecoms arrays, gyroscopes, and other "micromachines."

Alfautomazione expanded its product offering for the optoelectronics industry with the launch of its AlFiber3000 fibre-optic alignment system. The system is configurable for fibre-device, multifibre-device, and mulitfibre-device-multifibre processes, providing automatic control of the alignment process and flexibility to implement custom alignment routines. Imaging, motion control, and data acquisition are fully integrated into the system, which has a scan rate of 300 points/sec during alignment. The vision system of the AlFiber3000 allows for coarse alignment resolution of up to 5 mm controlled by imaging and allows shorter cycle times and higher setup flexibility. Alfautomazione's optical power tracking algorithm enables a rapid multi-axis alignment process. The AlFiber3000 supports automatic loading and unloading of components. Glue dispensing and UV curing as well as laser welding are available as options.

Limo is presenting its complete range of micro-optics for collimation, beam-shaping, and fibre-coupling for industrial high-power diode lasers at the forthcoming Laser 2003 Expo in Munich. The significant advantages of diode lasers can be widely deployed by using LIMO's optics in industrial applications. The collimation optics also benefit the beam-shaping of excimer lasers. Thus, LIMO is offering new homogenisation optics for lithography, material processing and medicine. LIMO's new M3 optics will be presented in Europe. They are already the basis for optical communications technologies for next generations of passive and active modulators, switches, and amplifiers.
For the first time, a "highest brightness" laser with 25 W at the output of a 100-µm fibre will be introduced. The offer of lasers with high power now also includes passively cooled lasers with output power up to 120 W.www.limo.deCommunication By Light (CBL) launched its scalable FiberMultiplier family. Highlights of the range are coarse wavelength-division multiplexer with four and eight channels. Up to eight independent channels can transmit different signals simultaneously over a single fibre pair. With its modular design the FiberMultiplier can be customised. Management occurs via the Web or simple network management protocol agent.
FiberMultipliers offer a range of parameters and diagnostic functions as well as monitoring the power level of incoming signals during operation. With interface adaptation of once-purchased modules as well as software and firmware upgrades, CBL offers its customers high investment protection. The FiberMultiplier transmits applications in wavelength ranges between 1470 and 1610 nm over one pair of fiber. Each single channel can transmit a maximum data rate of 1,250 Mbits/sec over distances up to 30 km.

Two new models have been added to Agilent's N4900 serial bit-error-ratio (BER) test series. The instruments are claimed to be the industry's first to provide built-in differential inputs/outputs, clock data recovery (CDR), and enhanced jitter, analysis, and measurement capabilities to enable R&D, design verification, and manufacturing engineers to perform full parametric measurements across a wide range of technologies and applications. The new testers cover frequency ranges of 150 Mbits/sec-13.5 Gbits/sec (N4901A) or 150 Mbits/sec-7 Gbits/sec (N4902A).
The N4900 test series can be used for design verification and characterisation of components, semiconductor chips, and modules as well as general-purpose applications in R&D and manufacturing.www.agilent.comKD Optics' range of fibre-optic test equipment, from handheld equipment to bench fibre testing products, are distributed by Tritec Developments, developer of fusion splicers and testers. "KD Optics' test kit is matched to our range of fusion splicing equipment," notes Jonathan Hunt, sales and marketing manager at Tritec. The multimode portable loss test sets (including the LTS23) consists of multimode power meters and LED sources designed for testing LANs. This design is carried over to the range of singlemode portable loss test sets that are ideal for testing all singlemode links. A cable TV option is available on all models. The range of visible light sources available for fault tracing in both multimode and singlemode fibre-optic cables includes the VLS40 visible laser source, which can be used with singlemode or multimode fibres. Both singlemode and multimode portable talk sets are also included in the range to provide a convenient communications link during installation or maintenance of optical fibre.
