Aerotech has developed advanced user-friendly active alignment utilities for fast photonics component alignment. A scan simulator is included to quickly determine scan parameters based on device size and energy distribution.

Standard routines include:
• First Light Alignment   Routines
• Spiral Rough, Step, or   Continuous
• GeoCenter
• Power Optimization   Alignment Routines
• Fast Align
• Spiral Fine
• Hill Climb
• Centroid

Each routine has setup parameters that can be quickly configured and saved. The standard MMI software has pull-down menus for user configuration, or parameters may be read, set, and saved directly in the user application program.

Spiral Rough can be run in step or continuous mode for fast first light detection. It stops at a user-programmed power threshold.

GeoCenter performs a raster scan to determine center of available energy over a programmed area and then moves to the center.

Fast Align is a 2D, 3D, 4D to ND rapid power peak alignment routine. It determines power direction and increases or decreases step size and direction as necessary.

Parameters include number and order of search axes, soft axis travel limits, power saturation threshold, convergence, and delay for meter settling.

Spiral Fine is similar to Spiral Rough except it completes the programmed spiral and then moves to the maximum energy found.

Hill Climb is a single axis peak or threshold search routine.

Centroid is a two-axis search that looks for a symmetrical drop in energy along two axes and then moves to center.

Scan Simulator is used to determine motion parameters. Users just enter beam and target size, and desired overlap and the system calculates the proper motion parameters for the power scanning. The scan simulator then simulates the power scan and time.
