SPIE PHOTONICS WEST 2018 PREVIEW


San Francisco will once again play host to two major international exhibitions in early 2018 – the BiOS Expo on 27 and 28 January, and the Photonics West exhibition from 30 January to 1 February – which will showcase the latest photonics components and systems. Here we preview some of what to expect at the event


unlike other filters that work on absorption. This feature allows the LOMA filters to withstand high laser power, as it attenuates the laser with no absorption of the input power.


The laser beam is transmitted without


Avantes will feature its expanded line of compact spectrometers at booth 1815, which includes the first-ever CMOS spectrometer with a 4,096 pixel detector. The Mini4096CL has both speed and sensitivity packed into a small footprint. Like all other AvaSpec instruments, the Mini4096CL is affordable, compact, and ideal for OEM integration. The Mini4096CL permits less than 0.2 per cent stray light and delivers a signal-to-noise ratio of 319:1. www.avantes.com


A new laser attenuator has been developed, which utilises an ultra-hard coated, Laser Optical Multilayer Attenuator (LOMA) filter from Delta Optical Thin Film. The laser attenuator enables computer-


controlled attenuation of a monochromatic light source from 1 to 99 per cent within the wavelength region of ~ 550-1,000nm. It provides the user with safe, repeatable, and real-time control over the attenuation by combining the LOMA filter with a linear drive, controlled electronics, and dedicated software. This filter is based on an optical thin film coating that works on reflection,


Cobolt, a part of Hübner Photonics, will highlight new wavelengths of 457nm, 473nm, 515nm, 660nm and 1,064nm on its 08-01 series, complementing the already available wavelengths of 405nm, 532nm, 561nm and 785nm. The 08-01 series of single frequency and narrow linewidth lasers are ideal for Raman spectroscopy. The 08-01 series consists of high


performance, ultra-compact, single longitudinal mode (SLM) diode pumped lasers (08-DPL) up to 400mW and narrow linewidth diode lasers (08-NLD) up to 500mW, all having very good wavelength stability and spectral purity. With integrated electronics, an integrated optional optical isolator and clean up filter, the lasers from the 08-01 series are easily integrated into high-end,


Raman-based systems or other analytical instrumentation. All Cobolt lasers are manufactured


using proprietary HTCure technology, and the resulting compact hermetically sealed package provides a very high level of immunity to varying environmental conditions along with excellent reliability. www.coboltlasers.com


distortion of the beam profile, and no extra optics are required. No pulse broadening is observed, even with short laser pulses down to 70fs. The optical coating works independently of polarisation, and it is designed for a wide range of laser wavelengths between 550 and 1,000nm. www.deltaopticalthinfilm.com


Edmund Optics will be exhibiting at booth 823 with a strong focus on laser optics, showcasing its new Nd:YAG laser line mirrors at UV wavelengths, divergence adjustable beam expanders and monolithic reflective beam expanders, in addition to a selection of its regular portfolio. Also at the booth will be product expos on a UV laser materials processing system, drone-based imaging for analysing the health of crops, well-plate inspection for advanced medical diagnostics and an exhibit visualising the firm’s manufacturing capabilities. The company will also be at Bios,


booth 8620, where it will present products specifically addressing the life science market. www.edmundoptics.eu


Excelitas Technologies will be debuting Qioptiq’s closed-loop modulation (CLM) feature for the iFLEX-iRIS and iFLEX- Gemini laser systems at booth 1031. The innovative CLM feature provides modulation capabilities without the need for recalibration, combined with ultra-low
