Ann: BluGlass secures first order of alpha GaN DFB lasers, page-7

your looking at a 'set piece' run order for a prototype to be successfully manufactured & tested off an R&D design flow
Prototyping completes the 4th step in this design flow leading to manufacturing the initial version of the product.
This remains part of the product ideation creation - costs will be covered / shared and remain 'claimable' via the R&D tax rebate scheme'
clearly there has been significant customer engagement to this point of the process with both parties moving to manufacture runs
should the prototype test successfully for the customer in those 'cutting edge' defence applications initial order quantity and revenue will follow
