PRODUCT UPDATE Positioning equipment DALi 3
Elliot Scientific has introduced the latest generation of DALi for automated photonic device alignment. The DALi 3 system is a natural evolution of the popular DALi 2, and is ideal for the following applications: fibre-to-laser diode alignment, fibre-to-waveguide alignment, fibre- to-fibre coupling, fibre array-to-device alignment, compensation for epoxy drift during pig tailing, compensation for drift during long-term characterisation, simultaneous alignment of input and output fibres (or arrays) to waveguide device.
A typical DALi 3 system consists of Elliot Scientific’s new 3-channel E1100 piezo controller, the matching E2300 USB-equipped DALi 3 interface, and a PC or laptop for driving the software. The system it is also suited to other piezo devices working on 0 to 150V.

IXFs series
A new series of OEM, single axis, optical mounts from Siskiyou offer high stability at a low price point. The IXFs series use Siskiyou’s monolithic flexure construction, in which the entire mount – both plates and springs – are fabricated from a single piece of metal. This configuration yields improved heat transfer through the mount over the traditional kinematic construction, resulting in significantly better pointing stability in the presence of temperature changes. And limiting the mount to a single axis of adjustment simplifies its construction, thus reducing cost.
IXFs single axis mounts are available for optics in the 12.7mm to 50.8mm diameter range.

LEDs and illumination
Hi-QE photocathodes Photonis has released of a new photocathode designed to provide a combination of extremely low dark counts, fast response time, and high quantum efficiency. Hi-QE Photocathodes are engineered to offer heightened spectral sensitivity in specific wavelength ranges for use in photon-starved applications, making them ideal for use in extremely low light level applications, including astronomy, biology, fluorescence, and plasma research. The Hi-QE Photocathode increases quantum efficiency (QE) by 50 per cent when compared to standard S20 photocathodes, while lowering dark counts as much as 10X with near- symmetrical pulse height distribution.

Spectroscopy Flame-NIR
Ocean Optics has launched the Flame-NIR, delivering powerful near infrared spectroscopy in a compact, affordable instrument. With a cost about one-fourth that of a traditional NIR system, Flame-NIR pairs a high performance uncooled InGaAs array detector with a small optical bench for spectral response from 950-1,650nm. Flame-NIR is sensitive, fast and easy to use.
Unlike other lower-cost NIR spectrometers, Flame- NIR uses an InGaAs diode array detector for high sensitivity with concurrent measurement of all wavelengths. Spectrometers come preconfigured or custom configured, with a replaceable slit design that
Aryelle 400
LTB Lasertechnik Berlin, a developer and manufacturer of short-pulse lasers, high- resolution spectrometers and laser-based measuring systems, has launched a new setup based on its high-resolution Aryelle 400 spectrometer in combination with a 2,048 x 2,048 pixels scientific grade CCD detector. The echelle spectrometer Aryelle 400, whose reliable optical setup was developed by the ISAS Berlin, has already been so far on top of high- resolution broadband spectrometers offering the
enables users to adjust resolution and throughput on demand. Complete systems, including accessories such as fibres and light sources, can be
configured for under US$10,000. Because its design is not dependent on
thermo-electric cooling, Flame-NIR has relatively low power consumption. This design, coupled with a small footprint (89.1 x 63.3 x 31.9mm) and low weight (265g), make it convenient to integrate into handheld and portable systems.

perfect solution for challenging measurement tasks like LIBS measurements on ferrous and non-ferrous metals.
The scientific grade CCDs with 2,048 x 2,048 pixels allow LTB to achieve a new
level of high resolution over a broad simultaneous wavelength range. For the range from 190-900nm a resolution of 15,000 is achieved, whereas for the range from 250-900nm LTB has realised a spectrometer setup with a resolving power of 50,000.

Sensors and detectors PowerMax-Pro HP
Coherent has extended its series of large area, high speed, PowerMax-Pro laser detectors to enable power measurement of laser beams of up to 375W continuously, 600W for shorter durations, and modulated peak powers as high as 15kW in intermittent (long pulse) operation. PowerMax-Pro detectors are based on Coherent’s proprietary thin film sensor technology that combines the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile, with the response speed
PML16 GaAsP, PML-SPEC GaAsP, and MW FLIM GaAsP
The new Becker & Hickl (BH) PML16 GaAsP, PML- SPEC GaAsP, and MW FLIM GaAsP multichannel, multiwavelength detectors are six times more sensitive than their multi-alkali predecessors. Using BH’s multi-dimensional TCSPC process, the detectors record 16 fluorescence decay
of a semiconductor photodiode. The new PowerMax-Pro HP model sensors will be particularly useful for materials processing applications based on high power fibre lasers, CO2
lasers, solid state lasers and
direct diode lasers, including welding, drilling, engraving and heat treating. Another important application area is with the pulsed lasers used for various aesthetic and surgical medical applications, such as
skin resurfacing, scar treatment, tattoo and pigment removal and hair removal.
