Nova is scalable for R&D projects, high volume production, and the rigours of high- reliability field installation. Wireless tablet control with a familiar


Android interface provides the programming flexibility required for research, as well as simplified step-by-step operation for manufacturing technicians. Workholder fixtures are easily interchangeable for each task, and optional videoscopes are available for real-time process monitoring and in-line surface inspection. Whether developing new optical devices,


improving component performance or manufacturing Telcordia-compliant cable assemblies, Nova is the ideal polishing system.

At booth number 5137, Laser Beam Products (LBP Optics), a worldwide manufacturer of industrial and


scientific metal laser mirrors and infrared optics, will be co- exhibiting with new owners ULO Optics. ULO Optics will be showcasing its new Compact2 range of CO₂ beam delivery equipment, along with the first of their range of fused silica collimators for fibre lasers. Compact2 is a cost-effective, low maintenance, modular solution to CO₂ beam delivery. Offering twice the power handling of the existing Compact range, the Compact2 range is suited to lasers up to 1kW with beam sizes up to 38mm.


Conference details


Talks by two Nobel Laureates will be among more than 5,200 technical presentations held alongside the Photonics West exhibition in San Francisco. The symposium is expected to attract an international audience of more than 20,000. Conferences are organised


into tracks on biomedical optics (BiOS), industrial laser sources and applications (LASE) and optoelectronics and photonic materials and devices (OPTO). Stefan Hell (Max-Planck- Institut Göttingen) and William Moerner (Stanford University), who shared the 2014 Nobel Prize in Chemistry with Eric Betzig (Janelia Research Campus) for their work in ultrahigh-resolution fluorescence


microscopy, will give details on the latest advances in the field. A comprehensive training


programme is set to offer more than 70 courses in lasers and applications, sensors, imaging, IR systems, and optical and optomechanical engineering, plus professional development seminars and industry workshops. Receptions and other


networking events will provide many opportunities to share ideas, connect around community issues such as diversity and inclusion, or to meet new potential collaborators.


HIGHLIGHTS New among this year’s 44 BiOS conferences – comprising


38 Electro Optics December 2017/January 2018


2,400 presentations – is the theme, ‘Photonic Diagnosis and Treatment of Infections and Inflammatory Diseases’. Nine talks in the popular BiOS


Hot Topics session will cover topics such as biophotonics for low-resource settings (Katarina Svanberg, Lund University and Sune Svanberg, South China Normal University) and near-future developments in photodynamic therapy (Tayyaba Hasan, Wellman Centre for Photomedicine). A multi-speaker


Neurotechnologies plenary session will include topics such as strategies for observing and controlling neural circuits (Ed Boyden, MIT) and in-vivo imaging of the brain (Na Ji, University


of California, Berkeley). Track chairs are David Boas (Martinos Centre, Massachusetts General Hospital, Harvard Medical School) and Raphael Yuste (Columbia University). A Nano/Biophotonics


plenary talk on shaped light will be presented by Kishan Dholakia (University of St Andrews, Scotland). The Translational Research


forum will present outcomes- based studies on technologies, tools and techniques with high potential to change the lives of patients. Organisers are Bruce Tromberg (Beckman Laser Institute and Medical Centre, University of California, Irvine) and Gabriela Apiou (Wellman Centre for Photomedicine,

LBP Optics will be exhibiting a range of


precision metal mirrors including gold- coated copper and aluminium. LBP mirrors are chemically polished to a unique, super- smooth finish and examples of these fully tested, super-polished metal substrates ready for coating will be on display. www.lbp.co.uk www.ulooptics.com


Lew Techniques will be showing its capabilities in the precision custom manufacture of submounts and carriers for laser diodes, laser bars, laser stacks and photodiodes. Product types include tungsten/copper (WCu) submounts with super-sharp edges (<5µm radius), allowing precise mount-edge positioning of laser diodes. WCu inserts brazed to solid copper bodies maximise heat-sinking, while minimising expansion mismatch between carrier and laser die.


Submounts in aluminium nitride (AlN)


with photo-patterned metallisation provide high-precision circuits. Metal structures can be tailored to meet individual requirements for soldering, wire bonding, electrical and thermal performance. WCu- and AlN-style mounts selectively


coated with a thin layer of AuSn solder allow accurate and consistent mounting of the laser die. Strict maintenance of metal coatings and solder alloy consistency ensure optimum reflow results.


Mounts for photodiodes on ceramics with


wrap-over conductors are also available. Circuits can be defined on multiple faces allowing greater interconnect flexibility, and ceramic can be precision-machined for the greatest functionality. www.lewtec.co.uk/


At booth 723, Ocean Optics’Ocean FX versatile spectrometer will be on show, distinguished by an acquisition speed of up to 4,500 scans per second, onboard processing for favorable SNR and reduced transfer time, and robust communications via USB, Gigabit Ethernet and Wi-Fi. The Ocean FX is an ideal choice for high-speed process applications, measurement of transient events and reaction monitoring. The Ocean FX is available in application-


ready, custom and OEM spectrometer configurations. The spectrometer can be integrated into other devices as a component, subassembly or turnkey solution. It is well suited for environments where fast sampling rates are necessary, such as monitoring sample colour, quality and other characteristics on a process line. In addition, the Ocean FX’s integration
