Avantes ( will be showing its new AvaSpec SensLine range of high performance, high sensitivity spectrometers. The Sensline spectrometers feature high quantum efficiency (QE) back-thinned CCD detectors along with the company's low stray light optical bench. The initial products released in this line are the AvaSpec-ULS2048x16-USB2 and AvaSpec-ULS 2048x64-USB2.

The AvaSpec-ULS2048x16-USB2 features a high-speed backthinned CCD detector with high QE for measurements in the UV to NIR range (200-1,160nm). The effective detector height with 16 pixels of 14µm is 224µm, and the pixels are vertically binned. Relative to the AvaSpec-ULS2048x14-USB2, Avantes first back-thinned CCD spectrometer, the new AvaSpec-ULS2048x16-USB2 supports much faster integration times (min 0.91ms), has improved dark noise, better etaloning, better anti-blooming and better dynamic range. The new AvaSpec-ULS2048x64-USB2 has an even higher detector height with 64 pixels of 14µm, vertically binned to an effective detector height of 900µm, resulting in four-times higher sensitivity. The AvaSpec-ULS2048x64-USB2 supports fast 1.75ms integration times and has similar dark noise, reduced etaloning, anti-blooming and dynamic range specifications as the 2048X16.

Common applications for the AvaSpec Sensline spectrometers are those requiring high sensitivity light detection such as fluorescence spectroscopy and low light-level detection applications.

Hamamatsu Photonics

Hamamatsu Photonics ( will introduce a new range of silicon detectors and image sensors that offer enhanced near-infrared sensitivity. Using unique laser processing technology, MEMS structures can be fabricated on the silicon surface, which act to reduce reflections and increase the surface area of the active element. This process drastically increases the sensitivity in wavelengths longer than 800nm.

The S11498 and S11499 series are a family of PIN photodiodes utilising this new technology, offering a high sensitivity of 0.4A/W at 850nm and 0.6A/W at 1,060nm respectively. The S11498 is twice the sensitivity and the S11499 three times the sensitivity of a typical silicon photodiode, making them ideal for a wider range of applications.

Also on show, the new S11500-1007 and S11510 series of Full Frame Transfer CCD (FFT-CCD) image sensors with ultra high sensitivity in the NIR region. By using our unique technology in laser processing, it is possible to form a MEMS structure on the rear side of the CCD, which allows the S11500-1007 and S11510 series to have a much higher sensitivity at wavelengths longer than 800nm.

Other products on display include the S11518 and S11519 silicon avalanche photodiodes (APDs), offering ultra high sensitivities at 1,000nm of between 70-75A/W at a gain of 100. Compared to conventional APDs designed for YAG laser detection, the S11518 and S11519 offer an additional 15-20A/W photo sensitivity, under the same operating conditions.

Specialised Imaging

Specialised Imaging ( will be displaying its latest product innovations and applications advances in ultra high-speed imaging.

Visitors will have the opportunity to review the latest revision of the SIM ultra fast framing camera, which is now capable of capturing up to 32 images at 1 billion frames per second. In addition all SIM series are now able to undertake multi-spectral imaging experiments allowing colour images to be taken at 3ns with interframe times of 1ns.

Unlike traditional ultra fast framing cameras the optical design of SIM cameras provide the choice of up to 16 separate optical channels without comprising performance or image quality. Effects such as parallax and shading, inherent in other designs, are eliminated and the high spatial resolution (>36 lp/mm) is the same from frame to frame and in both axes.

Individual ultra-high resolution intensified CCD detectors, controlled by state-of-the-art electronics, offer excellent control over gain and exposure allowing researchers total freedom to capture images of even the most difficult transient phenomena. The ability to mount individual filters on each optical channel provides the SIM with flexible spectral selectivity. An integral TFT monitor allows users to 'see what the camera sees' in real-time, thus allowing users to optimise focus and lighting easily.

Also on display will be wide range of new application data for review and discussion in areas including ballistics, combustion research, failure dynamics, elasticity, crack propagation, hypervelocity impact studies, shock resistance, medical research, detonics, impact studies, spray/particle analysis, PIV and nanotechnology.


Toptica Photonics ( will introduce a compact frequency-domain terahertz spectrometer.The system combines Toptica's new TeraBeam, a highly integrated two-colour diode laser, with newly developed InGaAs/InP emitter and detector technology (Fraunhofer Heinrich-Hertz Institute, Berlin, Germany). The new CW THz system features a fast scan option, which reduces the acquisition times in CW THz spectroscopy by more than two orders of magnitude and acquires a complete THz spectrum (e.g. 50-1200 GHz, sub-GHz resolution) in less than a minute.

Thus far, research in the field of frequency-domain (CW) terahertz has largely been carried out with GaAs photomixers, requiring laser wavelengths below 870nm. While excellent results in terms of bandwidth and signal quality have been obtained, the complexity of the optical source and a variety of non-standard optical components resulted in a price level inadequate for widespread industrial use.

Teaming up with the HHI, Toptica is now able to present an alternative solution: lasers and antenna packages for CW THz at the telecom wavelength of 1.5μm. The new TeraBeam represents a compact two-colour laser, with a footprint of only 161 x 130 x 61 mm³. Making use of highly integrated DFB laser diodes and fiber components, the laser provides 30mW per two-colour output and is thus ideally suited to the power requirements of the CW THz emitters and detectors. These modules, developed by HHI, are based on InGaAs/InP semiconductor material. The emitter utilises a high-bandwidth photodiode with an integrated waveguide structure, and provides output levels in the microwatt range. The receiver employs an InGaAs photoconductor and achieves excellent SNR values up to 80dB. The modules are fully packaged with SM/PM fibre pigtails.


Vytran ( will demonstrate its precision optical fibre processing equipment at the show. Vytran's product line-up includes a fully integrated workstation and discrete process tools for optical fibre stripping, cleaning, cleaving, splicing, re-coating and testing.

The company's director of technology, Dr Baishi Wang, will present a course on 'Splicing of Speciality fibres and Glass Processing of Fused fibre Components' during the conference, covering the fundamental principles of speciality fibre splicing and glass fusion processing.

Exhibitor image


Z-Laser ( will present its latest developments, including a green laser diode (515nm) with a power of 40mW integrated with the company's established M18 packaging and designed for industrial applications. The company states that the use of a laser diode eliminates the power fluctuation problems which can be typical of DPSS sources. Another benefit is the possibility of simultaneous digital and analogue modulation up to the MHz range, allowing for instant control loops under real-time conditions.

Applications can be found in structured light projection, as well as in biological and medical applications such as cytometry, microscopy or fluorescent applications where many markers are sensitive to the 515nm. Fibre coupling and an industrial grade temperature stabilized module will also be available at the show.
