High Power Narrow Bandpass filter (BPF)
Neptec’s high power Narrow Bandpass Filters (BPF) are used to selectively transmit 1064nm wavelength light. Narrow Bandpass Filters block out unwanted noise signals in EDFAs and fiber laser systems. Without a Band Pass Filter, the laser produced will be inaccurate and experience inconsistent power delivery.
Neptec offers a wide range of customization options including power handling, fiber type, polarization maintaining (PM), and packaging. If the standard BPF below does not fit your application, we would be glad to review your specifications and quote a custom BPS for you.
