Photoreaction apparatus
An object of the present invention is to provide a photoreaction apparatus which can inexpensively and quickly prepare a micropattern. The photoreaction apparatus comprises an LCD projector which irradiates an LCD panel for displaying an input image with light to thereby project the image; a sample laying stage on which a photoreactive sample is laid; a reducing projection lens which reduces the projected light from the LCD projector to form an image on the sample; and a zoom adjustment mechanism for adjusting a projective magnification of the image to be formed on the sample. The zoom adjustment mechanism comprises a first adjustment section for adjusting a distance between the LCD panel and the reducing projection lens; and a second adjustment section for adjusting a distance between the reducing projection lens and the sample.
