Day/Night Imaging in Color Applications
A dual bandpass filter pass visible light and a specific portion of the visible (VIS) and near-infrared (NIR) spectrums. They are ideal for color camera applications that utilize daytime sunlight and NIR illumination at night. These filters achieve accurate color rendition by blocking interfering wavelengths and eliminate the need for dual sensor imaging.
Mount & Size Options:
- Threaded mount sizes: M22.5 to M82
- C/CS mount, slip mount for lenses without filter threads, step-up/step-down adapter
- Custom shapes and sizes; mounted and unmounted versions available
