E2300 - DAli 3 Automatic Alignment Unit
Device Automatic Alignment System with USB Interface
DAli 3 Automatic Alignment Unit
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 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, 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 (see below). 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.
