The Day and Night Cameras which function as Color cameras in the daytime and high-sensitive monochrome cameras in the night, now come onstage as the surveillance systems expanded in their applications from the daytime to the night. However, ordinary lenses do not reproduce crisp images under IR Illuminations as sharp as the images under visible lights during daytime. That is due to chromatic aberration that causes the shift of focusing points under visible lights and IR Rays. Cosmicar/Pentax Day/Night Lenses are chromatic aberration corrected extensively in a wide range from visible lights to near IR Rays and are designed to reduce the focus shift to the unrecognizable level. The lenses display outstanding optical quality and performance in the range from visible lights to near IR Rays.
