ABSTRACT:
The present invention provides a visible and infrared light photographing lens system. A color separating prism or the like divides an object light entering a photographing lens and then passing through a focus lens, into an object light in a visible light region and an object light in an infrared light region. A visible light image pickup element and an infrared light image pickup element are used to pick up images of the respective object lights. Further, a compensation lens can be used to adjust a position where an image of the object light in the infrared light region is formed. Consequently, visible light photographing and infrared light photographing can be simultaneously carried out by focusing on an object at the same distance.
