PRODUCT UPDATE


Spectroscopy Spectis 5.0 Touch


GL Optic, a manufacturer of spectrometers and light-measurement instruments, has launched the GL Spectis 5.0 Touch, a compact spectrometer that can take laboratory-grade measurements of the intensity and colour of light. Suitable for measuring the light output of individual LEDs and LED-based luminaires, as well as for photo-biological safety testing, the new instrument can replace bulky bench- top spectrometers with no loss of accuracy or resolution.

Spectroradiometer with improved stability


The ILT950 spectroradiometer from LOT Quantum Design has had a machined optical bench added for reduced stray light and improved thermal stability. A new CCD array also results in more sensitivity over the entire spectral


Fingertip-sized micro-spectrometer


Hamamatsu Photonics has developed what the company claims is the ‘world’s smallest’ micro- spectrometer. The fingertip-sized spectrometer is an ultra-compact, lightweight and low-cost device which, according to Hamamatsu’s research, provides nearly the same performance as Hamamatsu’s MS series mini-spectrometer while


Laser and diodes Thor and Odin lasers MatchBox series CW micro lasers


Elliot Scientific has introduced the MatchBox series of CW micro lasers, manufactured by Integrated Optics UAB, for applications in chemistry and biophotonics, in particular Raman spectroscopy and fluorescence imaging. The series includes both DPSS and diode


lasers with a range of output wavelengths from 405nm to 1,342nm. The series has a small, robust and easy to integrate form factor, which is enabled by the monolithic design and semi- automated precision assembly process. The sealed, all-in-one laser head is powered by a low voltage DC supply and includes the optical components, drive electronics and thermal management within a single enclosure. Integrated Optics UAB also offer the Surface Enhanced Raman Spectroscopy (SERS) or Surface Enhanced Fluorescence (SEF) ‘Randa’ substrate. In this substrate, the active SERS area is silver-coated. www.elliotscientific.com


Cobolt, Swedish manufacturer of DPSS lasers, has released a family of pulsed lasers. The lasers consist of two series: the Cobolt Thor series of Q-switched lasers and the Cobolt Odin series of compact and tunable mid-IR lasers. The Thor series lasers are compact Q-switched diode pumped solid state lasers. The laser cavity design provides a combination of high pulse repetition rates (>7kHz), high average power (up to 1W), short pulse lengths (<5ns) and pulse-to-pulse stability. In addition, the


EM750 narrow linewidth lasers


Gooch & Housego has introduced the EM750 which represents a new generation of OEM narrow-linewidth lasers.


The EM750 stabilises the phase noise of the EM650 with passive G&H fibre optics. The laser phase noise is reduced for frequencies below 15MHz. Linewidths of <10kHz are


emission is generated in a TEM00 beam and with single-frequency spectral characteristics. Applications include range finding, Raman-lidar, micromachining and micromarking. The Odin series lasers are industrial-grade mid-IR laser sources based on a fully contained temperature tunable Optical Parametric Oscillator (OPO) and integrated pump laser, in a footprint of 125 x 70 x 45mm. www.cobolt.se


measures 111 x 210 x 58mm and weighs 1.5kg. It is equipped with a colour 240 x 320-pixel touch- screen display, so the user can configure


test set-ups and see measurement results without being connected to a PC. GL Optic has a physical resolution of 0.5nm and optical resolution of 2.5nm over a spectral range of 200-1,050nm. www.gloptic.com


Ultraviolet microspectrometer


Ocean Optics has released the STS-UV microspectrometer. Measuring 40 x 42 and 24mm, the device is for applications in the ultraviolet (190-


region. Specifications include: 200-450nm spectral range; 1nm resolution (50µm slit); dual calibration for higher accuracy (deuterium and QTH); and USB powered. Typical applications include characterisation of solar simulation and LED illumination and colour analysis. www.lot-qd.co.uk


being roughly half its size. The new C12666MA micro-spectrometer offers measurement in the visible wavelength range, and can be used for applications such as colour sensing in printing machines and LED lighting, point-of-care testing connected to smartphones, and other types of portable measurement. www.hamamatsu.de


650nm) including absorbance measurements, point-of-care diagnostics, emission spectroscopy and laser characterisation. The high signal-to-noise and wide dynamic range make the spectrometer useful for measurements such as determining the absorbance from dilute solutions. A selection of configurations allows users to optimise optical resolution to a specific application. The STS-UV is anchored by a 1,024-element detector in a crossed Czerny Turner optical bench. High linearity, absorbance repeatability and wavelength accuracy ensure reproducible results in large production quantities. High thermal stability performance and low baseline drift ensure that the data stays accurate under changing environmental conditions.


The STS-UV can be integrated into other


devices or set up next to a process line for quality control measurements or as part of a lab station. www.oceanoptics.com


achievable, sacrificing little of the power. The first versions are rated at 35mW across the 1.55μm wavelength C-Band.


The noise reduction is not wavelength- sensitive, so the EM750 can operate over the full tuning range of the DFB (~±75GHz) without compromising linewidth. www.goochandhousego.com
