DAli 3 Automatic Alignment Systems available with MDE piezo-driven XYZ Positioners
Elliot Scientific is offering the DAli 3 Automatic Alignment Systems with a choice of MDE123 or MDE125 Elliot Gold™ Series piezo-actuated XYZ flexure stages.
Two systems are available. The E2323 comprises a model E2300 2-axes automated feedback piezo controller plus MDE123 Elliot Gold™ Series XYZ flexure stage fitted with piezo actuators providing 25 µm of piezo adjustment in each of the three axes, or the E2325 with 100 µm of piezo adjustment. Both systems also offer 2 mm of manual adjustment in each axis.
The 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.

Elliot|Martock waveguide holders now with ‘in copper’ option
Elliot|Martock waveguide/device holders are now available manufactured from copper as a special order at additional cost. Any of the following MDE74x range can be supplied as such for applications requiring a heatsink capability.
- MDE741 – Basic, plain mount for tape or adhesive clamping
- MDE742 – Vacuum clamping
- MDE743 – Mechanical clamping
The new holders are mainly for use with Elliot Gold™ series flexure stages and the central workstations MDE881 and MDE883, but can also be mounted on the MDE147, MDE148 and MDE149 brackets. The MDE744, MDE745, and MDE746 models are special versions of the MDE741 to MDE743 models for use with the MDE717 and MDE718 fibre rotators.

New DAli 3: Latest in automated alignment for fibre optics and waveguides
The 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 fibers (or arrays) to waveguide device
A typical DAli 3 system now consists of our new 3-channel E1100 piezo controller, the USB-equipped DAli 3 interface, and a 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, it is also suited to other piezo devices working on 0 to 150 volts.
DAli 3 incorporates the latest in electronics and uses complex software algorithms to quickly deliver precision automated alignment. It does this by locating and optimising an optical feedback signal derived from the components being aligned. It then adjusts their relative position to optimise the signal and therefore their accurate alignment.
The software and hardware package includes many features to enhance use, while also providing the necessary flexibility to allow it to be incorporated into a wide range of photonic alignment tasks for development, test and production applications.
New THz-frequency contact probing for cryogenic applications from Lake Shore
Lake Shore have released details of their new THz-frequency contact probes. Compatible with Lake Shore’s CPX, CPX-VF, CRX-4K, and CRX-VF cryogenic probe station systems, the THz arm offers:
- Precise on-wafer contact THz probing of millimetre wave devices
- New measurement possibilities for next-generation electronics
- THz probes can be combined with standard DC/RF/microwave probe arms
- Features a low-loss THz waveguide
- Supports vector network analysers (VNAs) with suitable frequency extenders
- Enables calibrated S-parameter and other hf electrical measurements at cryogenic temperatures and in magnetic fields
Signal deterioration at frequencies above 75 GHz has limited high-frequency contact measurement of electronic devices at room temperature, let alone cryogenic ones. Now Lake Shore’s breakthrough technology of a specially developed low-loss THz-frequency waveguide delivers excellent signal integrity over longer distances, at lower temperatures, and with superior arm mobility. All without interefering with the other probes in the system.
