BPF (Band Pass Filter)
Band Pass Filters (BPF) are widely used in 3D sensing (ToF: Time of Flight) and biometrics.
Optrontec's BPF offers a variety options to choose the suitable filter type for the application.
The BPFs transmit specific wavelength bands while blocking others bands.
These types of the width of the BPF represent wavelength ranges and vary up to hundreds ㎚s, and are classified with three important characteristics: Center Wavelength (CWL) value of the passband, FWHM (Full Width Half Maximum) and maximum transmittance value.
