Dual Bandpass Filter Visible Blue
Midwest Optics SKU DB475. A Dual Bandpass Filter transmits two specific wavelength ranges while blocking shorter and longer wavelengths as well as some middle portion of the spectrum. These filters in particular pass visible light and some smaller portion of the near-infrared spectrum. Blocking most of the near infrared allows for excellent color rendition while retaining the ability to pass a specific LED or laser diode wavelength used for nighttime illumination.
