Abstract

PURPOSE:To realize a hologram lens having less aberration even when wavelength differs by arranging a light source at an adequate position. CONSTITUTION:A hologram lens converges laser light L of wavelenght lambda, which is incident to a hologram H from a point P1 at a distance f1 from the hologram H, to a point P2 at a distance f2 from the hologram H. In this case, light sources P3 and P4 which emit light of wavelength lambda0 are arranged at a distance fA from the lens H on one side and at a distance fB from the lens H on the other side, and 1/lambda(1/f1+1/f2)=(1/fA+1/fB)1/lambdaO, and 1/lambda(1/f1<3>+1/f2<3>)= (1/fA<3>+1/fB<3>)1/lambdaO.
