Heading to the MRS Fall Meeting next week? We welcome you to booth 423 to chat to our US Sales Managers who are eager to hear about your latest research and show you our latest lasers.
We are happy to present a poster at this years 27th International Conference on Raman Spectroscopy (XXVII ICORS). In our poster we will present the advantage of our 08-NLDM 785 nm narrow linewidth laser and how it can be applied to low frequency Raman Spectroscopy.
Title: Novel narrow linewidth 785 nm diode laser with enhanced spectral purity faciliates low-frequency Raman Spectroscopy
Authors: Magnus Rådmark, Gunnar Elgcrona, Håkan Karlsson, Peter Jänes and presented by Jetinny Ngo.

If you are interested in reading more about our 08-NLDM 785 nm narrow linewidth laser, about its design and application especially in low frequency Raman spectroscopy, then you will enjoy our white paper below on how low frequency Raman spectroscopy can be used in pharmaceutical inspection:
Analytica is drawing closer and we are looking forward to once again visit in person to see all of our customers and collegues on the floor again after the pandemic.
As a big player on the global industry for biotechnology, analysis and laboratory technology, Analytica remains an event we look forward to attending every year. Meeting new people and getting inspiration for new development projects is always an encouragement for us to make sure we can meet new expectations and innovative ideas.
This year we will be present in hall A2 booth 326 to show off some of our laser products, optimal for use within life science such as flow cytometry and fluorecense microscopy, to mention a few. You will be able to take a closer look at our VALO femtosecond lasers, the C-FLEX laser combiner as well as a range of Cobolt lasers, including the nanosecond Cobolt Tor and the narrow linewidth Cobolt 08-01 series.
We will have sales engineers present to show you all the capabilites and guide you through our sortiment, so feel free to send us a meeting request or request a visitors ticket to come see our products up close.
We look forward to seeing you there!
Thanks to rapid technology advancements in recent years, Raman spectroscopy has become a routine, cost-efficient, and much appreciated analytical tool with applications in material science and in-line process control for pharmaceutical, food & beverage, chemical and agricultural industries. Improvements in laser technology, detectors, and spectral filters, along with developments of new schemes for signal generation and detection, have aided Raman instrument manufacturers in overcoming the challenge of weak signals, which has accelerated instrument development and market growth.

CEO and founder Cobolt AB, a part of HÜBNER Photonics. Dr Håkan Karlsson founded the high performance laser manufacturer, Cobolt AB, in 2000. With a strong reputation for excellent quality cw lasers serving the life science and analytical instrument markets, Cobolt was acquired by HÜBNER to form HÜBNER Photonics in 2016.
WARSTEIN, April 29, 2021: S&I Spectroscopy & Imaging GmbH, a developer of high-performance spectrometers, today announced it has qualified the C-WAVE tunable laser from HÜBNER Photonics for use with their TriVista spectrometer system. The combination of the C-WAVE widely tunable continuous-wave (cw) single frequency lasers (covering wavelengths from 450 nm up to 3.5 µm) with the triple-grating spectrometer TriVista is expected to become a new standard for resonance Raman spectroscopy and microscopy.
“We are delighted to work with a renowned partner like S&I in order to help them advance the state of the art in resonance Raman spectrometers. The TriVista spectrometer with its exceptional resolution, sensitivity, and linearity over wide spectral ranges is a powerful instrument that revealed deep insights about the C-WAVE’s spectral performance. We are thankful for the excellent collaboration and the valuable feedback,” says Korbinian Hens, Chief Operating Officer and R&D Manager at HÜBNER Photonics Kassel.
“The combination of the TriVista spectrometer with the C-WAVE is a powerful and flexible solution for resonant spectroscopy methods, especially for the challenging low-frequency Raman range < 10 cm-1. The extremely narrow linewidth and very stable emission frequency of the C-WAVE paired with its outstanding spectral purity allows recording impressive Raman spectra: we were able to measure low frequency Raman bands at or below 5 cm-1 from the excitation wavelength even without filtering the excitation beam,” says Nils Timpe, Head of Sales at S&I.
For applications in Raman spectroscopy, most tunable lasers require elaborative filtering to suppress unwanted amplified spontaneous emission (ASE) which can cover the weak Raman signals. Cleaning up the laser’s emission spectrum can be challenging especially for the low-frequency Raman range close to the excitation wavelength. During qualification, the C-WAVE revealed no detectable ASE. Figure 1 shows a Raman spectrum of an L-Cystin sample recorded at excitation wavelengths of 455 nm and 520 nm.
Figure 1: Raman spectra of L-Cystine recorded at two excitation wavelengths employing the TriVista spectrometer from S&I with triple monochromator system (Teledyne Princeton Instruments Spectra Pro 750 HRS) in the high-resolution, subtractive mode with three gratings (2400 lines/mm), Princeton Instruments Pixis:256E detector cooled to -70°C (-90°F), and C-WAVE tunable laser from HÜBNER Photonics as the excitation source. The L-Cystin sample placed in a glass cuvette was measured in a non-confocal macro chamber at an incidence-angle of 60° to the resulting Raman beam path. The C-WAVE laser and TriVista spectrometer are shown to the right.
“The integration of the C-WAVE with our TriVista system went smoothly. The user-friendly software and automatic tuning functionality made it easy to control the laser. It is impressive that the C-WAVE’s beam position and pointing is so stable even after tuning over a range of 200 nm across the visible spectrum. This fact in combination with the perfect Gaussian beam profile reduces the complexity of the optical setup and helps speed up experimental work,” says Jannick Saatz, R&D engineer at S&I.
