high-speed gating at internal or external frequencies up to 100MHz surpasses the performance of existing detectors by 10 times, according to the company. Photons can be detected with probability up to 25 per cent at 1,550nm, while maintaining the dark count rate at low levels. A timing resolution as low as 250ps can be achieved. The id210 provides adjustable delays, adjustable gate duration from 1ns to 20ns and adjustable dead time up to 100µs. For applications requiring asynchronous detection scheme, the id210 can operate in free-running mode with detection probability from 2.5 to 10 per cent. Thanks to a practical user interface, all parameters can be intuitively adjusted with direct access buttons. Also on display are the family of visible photon counters and a short-pulse laser source.

lightpath technologies is a leading OEM manufacturer of optical components and assemblies. It specialises in bringing high-performance aspherical optical designs
Laser Components will show its Count line of single photon counting modules developed in partnership with PicoQuant. The modules achieve a quantum efficiency of more than 70 per cent at red wavelengths, and a higher QE at blue wavelengths than competing models. The Count series is based on a specially developed silicon Geiger-mode APD – one of the lowest-noise APDs on the
and assemblies into volume production for biomedical, industrial, defence, and communication applications. LightPath Technologies has developed a series of moulded infrared lenses using its BD-2 glass. The company is exhibiting its expanding catalogue of infrared imaging lenses for low cost thermal camera systems. On display will be MWIR/LWIR laser collimating lenses used
Laser Quantum will have its
in environmental analysis and infrared countermeasures (IRCM). The company’s technologies cover the spectral range from UV to long wave infrared (LWIR) and include advanced moulded aspheric optics, thermal imaging infrared lenses, fused fibre optic collimators, optical isolators, high- power gradium lenses and optical assemblies.

solutions will be showing its recently introduced OptoCooler HV37 module, the next product in its high-voltage (HV) line of thin- film thermoelectric coolers (TECs) for photonics applications with large heat pumping requirements.
market. Standard modules are available with dark count rates ranging from 20 to 250 counts, and modules with fewer than 10 counts per second are available upon request. The modules are available
with a fibre-coupled connection suitable for fibres with core diameter of up to 105µm, or alternatively as free-beam devices.

high-power Opus and Finesse lasers on display that are ideal for Ti:Sapphire pumping. The Opus laser is a ruggedised and compact package that delivers up to 4W of power at 532nm. The Finesse system is Laser Quantum’s established laser of choice with power up to 12W, noise at <0.15 per cent RMS and stability at 0.1 per cent
At 85°C, the OptoCooler HV37 can pump 4.5W or 107W/cm2 heat in footprint of only 6mm2
.
The device is 0.6mm high, making it one of the thinnest heat- pumping TECs on the photonics market today.
At 85°C, the OptoCooler HV37 can create a temperature differential (∆T) of up to 60°C between its hot and cold sides, and operates at a maximum voltage of 7.7V, making it
RMS along with a full five-year warranty for our scientific customers. Laser Quantum will also have its Ciel laser; at 473nm this laser can generate up to 350mW of blue CW. With that amount of power at 473nm, along with good collimation and a compact package, the Ciel is ideal for Raman and fluorescence materials imaging.

compatible with commonly found board-level currents and voltages. At 25°C, the device can create a ∆T of up to 50°C with a maximum voltage of 5.9V. The OptoCooler HV37 is RoHS-compliant and is manufactured using gold-tin (AuSn) solder, which enables assembly temperatures as high as 320°C. These assembly temperatures make the HV37 module compatible with industry
