TECHNOLOGY PRODUCTS Lenses and optics Water cooling delivers smaller HAZ


AdlOptica’s new Focal-piShaper has been optimised to operate with high power (>1kW) fibre lasers. This water cooled Focal-piShaper combines functions of collimation and beam shaping converting, with nearly 100 per cent efficiency. For example, a divergent Gaussian laser beam focused into a collimated beam can be optimised to create flat top, donut, and inverse gauss profiles near the lens’ focus.


Its advantages include efficient laser energy


usage, reduced heat affected zone, higher quality materials processing, compactness, easy integration in existing equipment, and operation


Good CO2 by copper


laser drilling conducted


Precision optical solutions manufacturer Reo now offers a range of copper high reflectors ideal for beam delivery and beam shaping tasks involving high power CO2


lasers.


These mirrors offer a combination of high reflectivity (>99.7 per cent at 10.6µm), excellent surface quality (40-20) and low scatter (surface roughness <50Å). They are produced from oxygen free, high thermal


Cut price deformable mirrors widen availability


Boston Micromachines has reduced the price of its deformable mirrors. The compact and affordable Mini-DM is ideal for low order wavefront control. Its mirror surface is controlled by 32 electrostatic actuators which


Fixed focus lenses get new focal length


Resolve Optics has introduced a new 15mm focal length lens expanding its range of fixed


with scanning optics. Potential applications include marking, selective laser melting, welding, scribing, dicing, micromachining, photovoltaics and drilling. www.pishaper.com

mirrors can be produced with plano, spherical or cylindrical surfaces over the 6mm to 150mm size range. Additional mechanical features can be easily accommodated. www.reoinc.com


in environments subject to radiation, the new f2 lens delivers high image resolution and minimal geometric distortion from 400- 750nm. Manufactured from cerium doped glass or synthetic silica, the Resolve Optics fixed focus radiation tolerant (non browning) lens range is able to withstand radiation exposure of up to 53kGy (53,000,000rads) and temperatures up to 55°C without discoloration. Available now in 6mm, 9mm, 15mm and 25mm fixed focus formats, Resolve Optics’ range of high performance radiation tolerant lenses have been designed for use with ½-inch, 2/3-inch and 1-inch closed circuit television cameras as well as Newvicon and Chalnicon tubes. www.resolveoptics.com


are individually commanded to achieve a desired shape. The Mini-DM is available in both continuous and segmented surfaces for adaptive optics or spatial light modulator applications. Mini-DM pricing now starts at $5,000. These new prices lower the barrier to entry for educators and allow them to demonstrate


adaptive optics in their classrooms. In addition, research labs will now be able to utilise MEMS technology with a reduced impact on their budget, which is hoped will stimulate innovation in applications including microscopy, retinal imaging and laser beam shaping. www.bostonmicromachines.com
