k-SCAN AOS’s world-leading FBG interrogation system. k-SCAN can provide up to 10 independent, simultaneously accessed channels each of which can contain multiple gratings. With an unrivalled multi-kHz update rate capability and a sensitivity and resolution which is second to none, the k-SCAN system is uniquely capable of multiple-input static and dynamic strain measurement.

Unpack, plug in and switch on; with the AOS TKLx family of turn-key laser diode systems, that’s all there is to it. Based on a combination of our PCx and LDDx Peltier controller and laser diode driver, the TKL instrument operates under the control of a laptop or other PC computer via the USB interface. We will source a laser diode to suit your requirements or will incorporate ones you specify. For non-standard wavelengths, we can offer you a custom-wavelength device at very reasonable cost.

CUSTOM WAVELENGTH LASER DIODES

Ever tried to source a custom wavelength laser diode only to find that you had to buy 10, 100 or even a whole wafer of devices? If so, then AOS can help! We can provide you with Fabry Perot or DFB lasers anywhere from 670nm to 2600nm at 1-off prices you won’t believe! We can package in simple TO cans for free space applications or in industry standard 14 pin butterfly packaging with SM/MM optical fibre output, Peltier control, isolation and back facet power monitoring.

The AOS PCx Peltier controller range is suitable for applications with drive currents of up to 3A. Based on a switching mode design, the controllers can achieve  +/-0.005ºC temperature stability and drive full load currents in most cases without the need for external heatsinking. The PCx range is available in several variants, from a simple, low-cost OEM PCB, via standalone to 19” rack mount. A USB option is also available which allows PC control and monitoring via a simple LabVIEW interface

The LDDx family is AOS’s complementary range of laser diode drivers, also available in OEM, standalone and 19” rack variants with a full PC control (via USB) option. In all cases, hard limits are set on board, to avoid overdriving the device in the event of PC failure or operator error. Depending on the laser type, it can be driven in constant current or constant power mode and operated CW or modulated up to 1MHz

DERIVATIVE SPECTROSCOPY DETECTION SYSTEM (PSD)

Intended for use in lock-in f/2f/3f detection systems for spectroscopy applications, the PSDx series of OEM modules provides a four channel phase sensitive detector, a multi-harmonic frequency generator with digital phase control and an optional laser diode driver in three stacked PCBs measuring 100mm x 100mm
