technology show review More from Munich Here are some more highlights from last month’s Laser World of Photonics
Aurea technology demonstrated time correlated single photon counting (TCSPC) measurements for quantum optics using its SPD_A_M2 all-in-one dual single photon counting module, along with a high- brightness photon-pair source and a commercial stand-alone TCSPC module.
Thanks to the combination of an exceptional low dark count rate below 5 x 10–6
per ns (< 5000cps)
and a photon efficiency of 20 per cent at 1550nm, the SPD_A_M2 module exhibits a coincidence to accidental-coincidence count ratio (CAR) better than 10,000 in continuous pumping regimes. The SPD_A_M2 is the latest generation of compact dual ultra- low-noise and high quantum efficiency single photon counting modules for near IR wavelengths (900-1700nm). The SPD_A_M2 integrates twin Geiger-mode InGaAs avalanche photodiodes, an efficient low temperature thermoelectric cooler, the electronic control and its intuitive interface in a compact box. The SPD_A series can also be used for other single photon counting applications.

Docter optics’ three business units presented at the show - Express Glass Services (EGS), Optical Systems (OSYS) and Precision Glass Components (PGC). The PGC unit produces molded optical glass components to meet
24 electro optics l june 2011
customer specifications, such as aspheres, arrays and free-form lenses. The business unit has just put a new glass furnace into operation to support the use of inline-fast- molding technology, which will permit large-scale production of optical components such as concentrators/ light pipes from the material immediately as it comes from the furnace. The company’s EGS provides
industry worldwide with precision, semi-finished optical products. The EGS unit recently enlarged its facility in Triptis, Thuringia, and is now poised to meet the most sophisticated customer requirements. The company’s Optical Systems business unit offers an array of services.

edinburgh instruments launched its MTL-5 laser at the show – a compact, user-friendly bench-top, mini-TEA (transversely-excited atmospheric-pressure) CO2
laser
capable of megawatt peak powers at 10.6µm. The MTL-5 is an upgraded version of the company’s MTL-3, and offers users enhanced functionality, reliability and built-in acoustic noise suppression. The laser is supplied with a separate 19-inch rack power supply, enabling users to optimise space without compromising their experiments. The laser is self-diagnosing, and has built-in fail safe mechanisms designed to support system integrity. An optional wavelength selection unit with precision grating control also enables users to step-tune easily between wavelengths. Pulse width is typically
50ns, with optional manual grating tuning and high repetition rates.

evatec demonstrated its enhanced capabilities for infrared thin film deposition, using either evaporative or sputtering technologies. Using a wide choice of coating
materials, Evatec’s enhanced GSM monochromatic and broad band monitoring capability can be used to accuratly terminate layer deposition for even the most complex IR
coatings.The company’s Optics Toolbox software further simplifies production by allowing seamless
translation of a thin film design into a coating recipe, and to the coating process itself. Optical pyrometry in evaporation systems further ensures temperature uniformities down to +/-3 per cent across the calotte for the best uniformity of process conditions.

Fianium released four new 8W supercontinuum lasers: SC450-8, SC450-8-PP, SC450-8-VE and SC450-8-PP-VE. The lasers offer excellent brightness over the spectral region of 450 to 2000nm. The VE systems are visible- enhanced, offering greater than 1.5W output power in the 400 to 750nm visible spectrum in a single-mode beam. An average visible brightness of more than 5mW/nm allows the VE systems to be used for applications
requiring high power visible light. The PP versions offer variable repetition rates which are useful for FLIM, FLIM-FRET and steady lifetime measurements. All of the company’s supercontinuum lasers are compatible with its plug-and-play supercontinuum accessories, including the new high power wavelength selecting AOTF-HP tunable filter module with standard visible, near-IR and IR crystal options.
