The filter is designed around a920nm center wavelength,
providing selective transmission within the near-infrared spectral region.
The10nm FWHM bandwidthcreates a relatively narrow
transmission window around the target wavelength.
This allows optical systems to isolate the required
920nm signal while reducing unwanted wavelengths outside the passband.
The10nm FWHMspecification provides controlled spectral
transmission around the 920nm center wavelength.
This bandwidth can be useful for applications requiring:
Custom bandwidths can also be considered for different optical system requirements.
The filter providesOD4 blocking outside the passband.
This deep blocking characteristic helps attenuate unwanted
wavelengths and reduce background signals that could interfere with optical detection.
The OD4 configuration is suitable for optical systems where
both narrow transmission and strong out-of-band suppression are required.
The filter provides a typical peak transmission of≥90%within the designed transmission region.
High transmission helps preserve the desired optical signal
while the narrow passband and OD4 blocking reduce unwanted spectral components.
