TECHNOLOGY PRODUCTS Lasers and diodes Boresight accuracy is cool


Z-Laser, a manufacturer of lasers and laser systems, has announced the release of its re-designed ZQ family of laser sources. The new versions offer higher power and outstanding beam and laser line quality for several types of projections: fibre, homogeneous lines, collimated beam and structured light. The new ZQ2 high-precision laser source system boasts a boresight accuracy of less than 3mrad and outputs up to 7000mW at wavelengths between 600- 1100nm.


The Z1000Q1-F-808 has an output of 1W at 808nm and is accurate to 300μm (FWHM; in 1500mm focus), making it ideal for applications that require high measuring resolutions. The internal design of the ZQ1 is laser coupled with an integrated thermoelectric cooler that allows a high level of stability and minimum bore sight error. Both products feature integrated optics, electronics and active temperature control in a self-contained enclosure and support a variety of communication interfaces: RS-232, USB, Ethernet, PLC, each of them galvanically isolated. www.z-laser.com


Compact heads are name of the game


Laser Quantum has announced a redesign of its popular Ventus laser range into more compact heads with significant improvements in beam quality. Noise levels are down from two per cent to 0.5 (0.15 per cent for the higher powers) and power stability from 2 per cent to 0.4 per cent. M2


, divergence, and weight have also been


improved. The Ventus was first launched in 2001 as a mid-powered green laser for scientific laboratories. The family has grown to offer


Gaussian light distribution lasers get homogeneous


Laser and laser system manufacturer Z-Laser has announced that its ZM12 family of small lasers now supports homogeneous light distribution (HLD). Following the integration of the new Powell lens technology into its ZM18 laser family, Z-Laser has adapted the improved HLD technology for these products, which were previously only available with Gaussian light distribution.


a range of power from 50mW to 1.5W in a number of different laser heads. www.laserquantum.com


Encased in a 45mm housing, the ZM12 laser projects a line with +/-5 per cent homogeneity of light distribution. The homogeneous light distribution means machine vision algorithms will produce results with greater accuracy than with Gaussian light distribution.


When using slightly longer camera exposures for applications that previously might have required a speckle-reduced laser this kind of homogeneity can produce excellent results, according to Z-Laser. www.z-laser.com


Spectroscopy


Triggers at the ready for CCD miniature spectrometer


Ocean Optics has added triggering functions to its Maya2000 Pro back- thinned CCD miniature spectrometer to provide accurate timing and synchronisation between the spectrometer and other devices. Triggering provides precise timing


between devices. The Maya2000 Pro can be triggered so that sending the spectrometer a pulse causes it to do something such as turn off or on a light, activate a pulse in a pulsed light source or start or end spectral acquisition in the spectrometer. For example, in the External Triggering mode, an event outside the sampling system (such as a button push, lever activation or laser) electronically pulses the spectrometer’s trigger pin and starts acquisition of the spectra with microsecond accuracy. With the triggering functions, three low-jitter trigger and normal operating modes are now possible. Applications include pulsing a light source to occur when acquiring a spectra and synchronising spectral acquisition to coordinate with samples moving through a process stream

Supercontinuum could have modular future


Newport has introduced its SCG-02 Wavelength Extender to its line of nonlinear microscopy and spectroscopy application solutions. The Wavelength Extender is specifically designed as a modular solution for supercontinuum generation when used with femtosecond Ti:Sapphire lasers, such as Newport Spectra-Physics’ Tsunami, MaiTai DeepSee, and MaiTai ultrafast oscillators. The SCG-02 is pre-aligned and can be integrated easily into ultrafast light sources. The laser input is split into two parallel


or sensors reaching a certain temperature level. In addition to triggering, Ocean Optics has enhanced Maya2000 Pro performance with support for RS-232 communications and improved optoelectronics that increase dynamic range (to 15,000:1), lower trigger jitter (to 100ns) and decrease dark noise (to 6 RMS counts). www.oceanoptics.eu


beams, the fundamental pump, and the parallel, unfiltered broadband supercontinuum. This flexibility allows for both the external selection of particular spectra of interest, and the independent use or recombination of both beams. The fundamental beam passes through an integrated attenuator to enable precise control of the output power. www.newport.com
