Tunable Bandpass, Tunable Wavelength Filter Module
 |
Tunable bandpass, tunable wavelength filter modules (TBTFM) enable simultaneously varying the bandpass and center wavelength of the filter. It consists of two multi-cavity thin film filters with 18 nm bandpass with very steep walls. The bandpass can be varied from 2 nm to 18 nm, and the center wavelength can be tuned from 1525 nm to 1560 nm.
The TBTFMs are ideal for spectral slicing of supercontinuum generated by femtosecond fiber lasers to produce continuously tunable pulsewidths at the desired wavelength.
The modules are available with standard fiber or polarization maintaining fiber pigtails.
