PURPOSE: An image taking lens is provided to prevent a phenomenon which darkens the peripheral part of a screen by adjusting the maximum angle of emergence of main light radiated to a light receiving unit. CONSTITUTION: A first lens(10) includes plus refractive power. A second lens(20) includes minus refractive power. A third lens(30) includes minus refractive power. A fourth lens(40) includes minus refractive power. A fifth lens includes plus refractive power. The objective side of the first lens is convex shape. The objective side of the third lens is concave shape. The phase side of the fourth lens is convex shape. The objective side of the fifth lens is convex shape. |
