Day/Night is a popular term for lenses and other products which are optimized for operation in both daylight and low-light conditions using an infrared illumination source. Such products require specialized design and manufacturing techniques to provide good image quality under this broad range of spectral conditions. Using a Day/Night lens under these circumstances can improve focus, brightness and resolution over conventional lenses. Sunex also offers specialized Day/Night filter products which can further optimize your application.
Day/Night Filters
These are special IR cut-off filters (IRC40 type) designed to allow both visible
light and narrow band of NIR band to pass through. Please refer to
Day/Night filter page for details.
Day-Night IR Exchanger
The M12-EXM-IRC21 is an IR cut-off filter exchanger with integrated lens mount
that allows true day/night (TDN) operation with the Pixim DPS chipsets. For
daytime operation an absorptive color filter provides true color rendition. At
night, an AR coated window allows maximum light transmission.

Day/Night Lenses
The following lenses are designed to cover an extended spectral range of visible
to near-infrared wavelength (NIR). The designs are achromatized over the entire
visible and NIR wavelength so the focal shift between the visible spectrum and
NIR is minimized.
