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