Fast Axis Collimator Arrays

Fast Axis Collimator Array

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.
