About the Author
Kevin Carmichael is Senior Marketing Product Manager for Lake Shore Cryotronics responsible for material characterisation systems and instrumentation. This includes the company’s new line of high-performance, simple-to-use MeasureReady™ I/V sources for engineers and scientists requiring a very precise, low-noise source of current or voltage in the lab.
We are exhibiting at Photonex – the UK’s premier annual event dedicated to the science of light – from tomorrow.
On Wednesday, October 11th and Thursday the 12th, members of our team of engineers and scientists will be on hand to discuss Elliot Scientific’s Solution Science capabilities. We will also be demonstrating our world-famous Elliot|Martock XYZ Flexure Stages and smooth backlash-free miniature slides, and you can also experience some of the many products we offer manufactured by the North American and European companies we represent.
So visit Stand B10 at Photonex in Coventry this week and discover how the equipment, systems and instruments we offer support the UK and Ireland’s scientific, research and industrial communities.
If you cannot make it to the show, have a look at our latest newsletter instead…
The Elliot Scientific October newsletter is now available. In this issue we feature a number of products that we will be exhibiting at Photonex. Elliot|Martock flexure and miniature stages take pride of place alongside equipment from Energetiq Technologies, HOLOEYE Photonics, Mad City Labs, Vescent Photonics and many more…

Photonics Ireland is a biennial conference that this year is being held from tomorrow (13th September) at the Radisson Blu Hotel in Galway.
Elliot Scientific is exhibiting at this premier event for Photonics research in Ireland, and we will be demonstrating a broad range of products; both our own and from companies we represent – some exclusively – in the British Isles.
High profile national and international speakers will showcase some of their latest research and achievements in Photonics. Topics will include:
- Biophotonics and Optical Sensing
- Laser-Materials and Laser-Plasma Interactions
- Nanophotonics and Plasmonics
- Optical Communications and Networks
- Photonic Integration and Packaging
- Photonic Devices and Photonic Materials
- Quantum Optics and Technologies
Gamma Scientific, in conjunction with Laser Focus World magazine, are delivering an exciting Webinar presentation on Tuesday, September 12th that will provide in-depth product information, typical applications, and visual demonstrations of the flexible software and production interface capabilities that give the RS-7 SpectralLED™ Tunable LED Light Source so many advantages over traditional halogen and other LED light sources.
Register for the Webinar here.
The RS-7 SpectralLED™ delivers superior spectral resolution and accuracy with higher brightness and a broader colour gamut than any other currently available halogen or LED-based source for camera and image sensor calibration.
The RS-7 features 35 discrete LED channels, each having 16-bit resolution in intensity settings enabling it to be programmed to produce a uniform output that closely matches virtually any illuminant source in a single compact and versatile instrument.
SpectralLED™ can sweep through wavelengths to simulate a scanning monochromator, but with the advantage of no moving parts. In addition to superior spectral resolution and accuracy, the SpectralLED™ also offers about 10x higher brightness than any competitive product. This allows measurements over a much larger, linear dynamic range, and is sufficient to illuminate virtually any detector at levels up to saturation.

Fibercryst is the only manufacturer of short pulse lasers and amplifiers that utilise the innovative Single Crystal Fibre technology (SCF) – a technology that offers significant performance advantages over existing technologies.
The FEMTO-30 is Fibercryst’s latest and more powerful laser system. This 30 W laser can deliver pulse energies of 160 µJ (@ 100 kHz) in pulse widths of less than 800 fs, with repetition rates selectable between 100 kHz and 1 MHz.
A significant feature of this laser is the ability to easily and quickly change the repetition rate to favour the average power or the energy per pulse. This makes it ideal for:
- Cutting and drilling of hard materials
- Cold machining of polymers and composites
- Micromachining and structuring of surfaces, for example medical devices and semiconductors

HOLOEYE has launched a new enhanced electronics driver module for existing and forthcoming Spatial Light Modulator (SLM) panels. The PLUTO-2 features an HDMI interface for addressing phase functions, a USB connection for advanced calibrations, and a trigger sync output for synchronising with external devices – such as colour-switchable lasers. The driver’s faster addressing speed allows for a colour-field-sequential (CFS) mode at 180 Hz input frame rate with the matching new PLUTO-2 SLMs and, as a bonus, also offers a more stable phase response.
The PLUTO-2 driver is equipped with a dual-core processor and on-chip memory, enabling user-programmed (Ubuntu™) additional functionality. For example, a slideshow of images can played back from a USB stick or internal memory without the need for a PC.
HOLOEYE has also added to their newly developed dielectric mirror range of panels. These enable use with higher incident power lasers due to the SLM’s coating, which reduces absorption. The models currently available are:
- PLUTO-UV-043: 350 to 420 nm with 90% reflectivity and >2.3π; phase retardation up to 405 nm
- PLUTO-VIS-056: 450 to 650 nm with 93% reflectivity and 2.5π phase retardation at 530 nm, 2.1 at 633 nm
- PLUTO-NIR-049: 1000 to 1100 nm with 93% reflectivity and 2π phase retardation up to 1064 nm

IPG Photonics makes a number of fibre laser systems available specifically to the research community.
CW Green Fibre Lasers
A variety of science and medical research applications can benefit from a green laser and IPG’s GLR series of single-mode, single-frequency, linearly polarised continuous wave (CW) 532 nm fibre lasers with output powers up to 30 W are ideal for these purposes.
These highly efficient and reliable lasers feature a super-compact lightweight optical head connected to an air-cooled rack-mounted main laser console. The all-fibre construction allows for full range adjustment of output power without changes in power stability or beam mode parameters.
For more information about these or other lasers IPG offers through Elliot Scientific, please contact us.
A new turnkey, drop-in calibrated light source for custom and commercially available wafer level testing of CCD and CMOS sensors has been developed by Gamma Scientific from their existing digitally programmable, colour tuneable, RS-7 LED light source.
The new RS-7-4 can deliver virtually any arbitrary spectral power distribution of visible light over a wide range of output luminance. This makes it ideal for accurately characterising a detector’s dynamic range, uniformity, linearity and spectral responsivity.
The RS-7-4 outperforms rival systems due to highly stable DC drive current circuitry that varies the output luminance of manifold discrete LED channels, rather than using pulse width modulation (PWM). This is critical when testing high speed silicon detectors, which can easily time resolve PWM signals and thus give measurement errors.
