A bandpass filter that selectively transmits near-infrared light at 940nm!
The 940nm bandpass filter is a bandpass filter that selectively transmits near-infrared light at 940nm. It has spectral characteristics that minimize the transmission (and maximize the reflection) of visible light and some infrared light. The film is formed using ion-assisted deposition (IAD), resulting in a shift-free and dense film. For more details, please contact us or refer to the catalog.
