If the Samsung Lenses have DN at the end of the product code, the lens is suitable for day and night functions. Since the refractive index of visible light and the refractive index of infrared light are different from each other, the distance of the lens focusing on the CCD sensor is different from each other in day and night situations. When the camera is operating during daytime (color), it is released by adjusting the sharpness. However, from the moment of switching to night function (Black and White Image Capture), there will be a slight deterioration in sharpness due to the difference in refractive index. Since the lenses ending with the DN code have a lens structure that corrects the infrared rays, smooth images are obtained without loss of sharpness in both day and night functions.
