The MidOpt LP645-25.4 is recommended for night vision applications using a filtered broadband light source; incorporating an LP645 filter blocks most visible light while passing deep red and NIR wavelengths. To block longer wavelengths, including the infrared, see our BP660 or BP695 Bandpass filters. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
