based on the result, if the optical system u design can fulfill the requirment, then we can discuss the cost. would you send me you phone number which I can reach u now? caodonggg@yahoo.com.cn
reply to :准直后的光斑需要多大?
如果你是要与200um的光纤耦合的话,LD出来的光直接用单个透镜汇聚就可以,而非需要准直。因为准直之后,你仍然需要将光汇聚入光纤。不过考虑耦合的难度,可以考虑先准直后汇聚的办法。
我实际需要的是准直光,耦合进光纤只是想用现有的光纤准直器技术,但现在看来用光纤准直器做到光束发散度<1mrad难度很大,所以如果采用方案2.也需要对光纤准直器进行单独设计! Have good idea or solution, Please contact me!
