Abstract
PURPOSE: To obtain a long distance between the object surface and the front surface of lens system, and the rear surface of lens system and the spectrum surface as the Fourier tansformation lens, by constituting in eight groups with eight lenses and satisfying the specific conditional formulae.
CONSTITUTION: Sequentially from the object field side, the first group comprises a poitive single lens L1 having the convex face directed to the object field side, the second group comprises a meniscus negative lens L2 having the convex face directed to the object field side, and the third and fourth groups comprise negative single lenses L3, L4 having the concave face directed to the object field side, and the fifth and sixth groups comprise meniscus positive single lenses L5, L6 having the concave face directed to the object field side, the seventh group comprises a positive singla lens L7 having the convex face directed to the image field side, and the eighth group comprises a positive single lens L8 having the convex face directed to the object field side, thus constituting in eight groups with eight lenses. At the same time, conditional formulae 1 to 6 are satisfied. (f is the focal length; d is the distance on the axis; and n is the refractive index).
