For microassembly projects with an emphasis on product development desktop solutions are there to speed up the feedback cycles. Highly precise nanopostioning and microgripping technology is extended with supportive functions and modules such as the Lens Alignment Module.
Case Study: Automated FAC Alignment Station
The FAC Alignment Station automates the assembly of Fast Axis Collimation (FAC) lenses to laser diodes. The process starts with contacting laser modules and completes with the final measurements of beam collimation after adhesive curing. The alignment of the lens in front of a multi-emitter laser diode bar is achieved in less than 25 seconds.
Upon loading, the laser modules are centered and connected automatically. The laser mount serves as heat sink.
Controlled amounts of adhesive are dispensed. Here we employ a needle valve dispenser.
Sensor feedback from the beam analysis optics is used to precisely align the lens in front of the laser using a SmarPod.
After adhesive curing the final optical characteristics are measured.
The assembled module is released to be unloaded.
