New electronic Polarisation Controller/Scrambler from OZ Optics

OZ Optics now offers a high speed electrically operated Polarisation Controller (EPC) that provides continuous polarisation control with negligible insertion and return losses in a compact, easy to operate package. Four birefringence transducers, each controlled by an analogue input signal, modify the polarisation in orthogonal directions. The device can be operated from 1260 to over 1650 nm (custom wavelengths available) with the response speed of each transducer surpassing 30 kHz.

EPC-1276-2016-01

Applications include polarisation controllers for optical networks, Polarisation Dependent Loss (PDL) control, Polarisation Mode Dispersion (PMD) compensation modules, and polarisation scramblers for polarisation parameter characterisation systems. The redundant transducer design allows continuous control of polarisation without having to ‘reset’ voltages.

High Speed Polarisation Controllers are offered as base modules requiring external electrical signals to operate, OEM modules with driver electronics and control interface, or stand-alone benchtop test instruments. For more information, please contact us.

Both systems also offer 2 mm of manual adjustment in each axis.

E2323_1200AThe Elliot Scientific DAli 3 is the latest version of our popular automated photonic device alignment system 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 pigtailing
  • Compensation for drift during long-term characterisation
  • Simultaneous alignment of input & output fibres (or arrays) to waveguide device

A typical E2300 DAli 3 system now consists of our new 3-channel E1100 piezo controller, the USB-equipped DAli 3 interface, and a customer-supplied PC or laptop for driving the easy to use software. Although designed to complement the piezo-driven versions of the Elliot Gold™ Series range of flexure stages, such as the MDE123 and MDE125 described above, it is also suited to other piezo devices working on 0 to 150 volts.

  • Output noise: < 50 µVRMS
  • Output stability: <0.01% over 16 hours
  • Includes software drivers, LabVIEW examples & tutorial, and C# GUI
  • Rack mounting option

Please contact us for full specifications and pricing information.


New Model 372 AC Resistance Bridge/Temperature Controller

372blogLake Shore is now offering their new Model 372 AC Resistance Bridge/Temperature Controller for experiments requiring precise and accurate AC resistance measurements.

The Model 372 has a number of improvements in design and performance for greater accuracy when making temperature measurements at very low temperatures. The streamlined front-panel keypad interface and a customisable front display along with control, configuration, and monitoring software, make the Model 372 easy to use no matter what the application.

Monitor and frequency reference outputs for direct connection to external devices or equipment are supplemented with Ethernet, USB, and IEEE-488.2 connectivity. (LabVIEW™ drivers are available)

To complement the new controller, Lake Shore have also introduced the Model 3726 scanner option designed for connecting up to 16 ultra-low temperature measurement points. With lower input noise and DC bias current, the new scanner takes full advantage of the performance improvements built into the Model 372 and offers superior performance to previous generations.

Lake Shore Model 336/350 Low Temperature Controllers Get 4 Additional Inputs Option

Lake Shore is now shipping its new Model 3062 4-channel option card for the Model 336 and Model 350 temperature controllers, doubling the number of inputs by means of an inexpensive plug-in board.  These widely used Lake Shore controllers use cryogenic temperature sensors for monitoring or control, and can be configured for diode, negative temperature coefficient resistor, or positive temperature coefficient resistor sensors.

The new Model 3062 scanner card can easily be installed in the lab, so there is no need to send the controller back for upgrade. The card is supported by Model 336 firmware version 2.3 and later, and the Model 350 firmware version 1.1 and later. To update either model, you can download the free Firmware Updater software along with the latest firmware release.

Visit our Lake Shore pages for more information on this and their other products, demo videos, and application notes. Alternatively, contact us for pricing and detailed specifications.

Materials characterisation using the Vibrating Sample Magnetometer

Materials characterisation using the Vibrating Sample MagnetometerLake Shore Cryotronics are exhibiting at the Materials Research Society (MRS) Fall Meeting from November 26th to 30th at the Hynes Convention Center in Boston.

They will be highlighting their wide range of sensors, instruments, and systems used for high-precision materials characterisation research, including their line of cryogenic and cryogen-free probe stations, the new 8404 Hall effect measurement system and Model 336 cryogenic temperature controller.

Lake Shore experts will be on-hand in Booth 800 to discuss recent research developments, talk through any applications issues that scientists are encountering, and help suggest solutions to these issues.

Lake Shore Model 350 Ultra-low Cryogenic Temperature Controller now available

Lake Shore announced their new ultra-low cryogenic temperature controller – the Model 350 – back in February, but now the physics community can actually start to receive their orders as the first models roll off the production line in Westerville. The Model 350 is designed for the demands of pumped He-3 refrigerators, adiabatic demagnetization refrigerators (ADRs) and a number of other dilution refrigerators, providing excellent measurement performance, superior control accuracy, and convenient operation for a wide range of advanced research applications.

Patented noise reduction input circuitry is just one reason why this controller works so well for ultra-low temperature (ULT) applications, all the way down to 100 mK. When combined with precision Cernox sensors, this performance-optimised design allows as little as 10 nA of excitation current to be used, minimising self-heating effects, and ensures best possible measurement accuracy throughout the entire temperature range. The instrument offers extraordinary capability and flexibility, often eliminating the need for additional instrumentation in a refrigeration control system. Its four input channels and four independent control outputs are configurable to support a broad range of I/O requirements, including the heaters and auxiliary devices typical of ULT refrigeration systems, as well as other cryogenic sensor types like ruthenium oxide and platinum RTDs.

For more information and pricing of this and other equipment in the Lake Shore range, please contact us.
