Fast Axis Collimator Arrays

Description+

PowerPhotonic’s range of fast axis collimator arrays (FAC) is designed to interface to complete laser diode stacks.  They allow the entire diode stack output to be collimated with a single element, providing an ultra-compact and robust solution that radically simplifies the cost and time of assembly of the complete system. 

The FAC array can either be specified with a standard bar pitch or, for optimal performance, matched to the diode bar stack using bar pitch data provided by the customer.  As a further optimization, PowerPhotonic offers customers the ability to customize the FAC array to tailor the far field profile to meet specific application requirements.
