1025nm PM Band Pass Filter
      1025nm PM Band Pass Filter is a fiber passive component which is based on thin-film filter technology, it can block the 
unwanted wavelength signal and pass the specific wavelength band. It's widely used in fiber amplifier and fiber laser field, 
the high power type is also available upon request.
