Day/Night Imaging using Dual-Bandpass Filters
To achieve accurate color rendition in applications using a color camera during the day and infrared (IR) illumination at night, a Dual Bandpass Filter is an ideal solution. Dual Bandpass filters pass visible light and a narrow wavelength range in the near-IR spectrum that directly corresponds to the emission wavelength of the IR illumination that is used. This helps to ensure imaging results that are clear and accurate under most lighting conditions.
