Abstract:
An imaging optical system includes a plurality of lens groups each moving such that spaces between each one of the plurality of lens groups change during a zooming. The imaging optical system conjugates a conjugate point on a magnification side and an intermediate imaging position, and conjugates a conjugate point on a reduction side and the intermediate imaging position. The imaging optical system includes a first lens group located at a furthest place on the magnification side and a rear group in this order from the magnification side toward the reduction side. The first lens group includes a field curvature correction lens group moving along an optical axis when an amount of a field curvature is changed, and a focusing lens group. The imaging optical system satisfies condition (4) below: |{(1− βcw 2 )×β crw 2 }/{(1−β fw 2 )×β frw 2 }|<0.2   (4)

Claim (Index 15):
The imaging optical system according to  claim 13 , wherein the lens of negative power located farther on the magnification side than the high transmittance lens has an absorption coefficient equal to or greater than 0.008 at the wavelength of 400 nm of the transmitted light.
