Visitors can see this and other instruments at our booth #1815
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 applications.
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.

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 ~ 550-1,000 nm. 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, 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 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.
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.
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 noise and high-power stability performance over the laser lifetime. It is ideal for biomedical imaging and metrology applications where repeatable performance and low signal-to-noise ratio are required.
Unlike traditional open-loop laser modulation, the iFLEX CLM maintains consistent output during both continuous-wave and modulated operation. The CLM feature enables analogue, digital and dual-mode modulation for reliable stability from 0.1 per cent to 100 per cent power and maximum repeatability for ultra-stable performance. IFLEX Lasers with CLM are also ultra-low noise in terms of RMS, RIN and periodic noise. They offer precision adjustment at all output power levels for applications where a stable, ultra-low noise source will improve signal-to noise ratio and data consistency over time.
The laser diode module for 3D vision systems to be showcased by Frankfurt Laser Company from its HAML-F Series is compact, reliable and delivers a highly uniform and stable line output beam. It comes in visible and IR wavelengths with up to 100mW power output and is graded at IP67 for industrial protection.

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.
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 color, quality and other characteristics on a process line.
In addition, the Ocean FX’s integration periods can be as brief as 10µs, effectively managing saturation intensity when measuring high-intensity sources and plasmas. Indeed, the Ocean FX acquires spectra with such speed that short-lived events can be measured confidently and otherwise undetected spectral effects made evident.
