Title:
LIQUID CRYSTAL EXPOSURE DEVICE
Document Type and Number:
Japanese Patent JP2011013513
Kind Code:
A
Abstract:
To prevent interference between the periphery of a mirror and a holding plate when a flat mirror is heated to a high temperature by a reflected light and is deformed.
A groove is provided at a face that interferes with the periphery of the flat mirror of the holding plate, which in turn holds a first flat mirror that bends a direction of light from a lamp and selects a wavelength of the light from the lamp. Further, a member for providing a space between the periphery of the first flat mirror and the holding plate is provided. Alternatively, a holding face whose size is smaller than the size of the flat mirror is provided at the holding plate. Alternatively, a tapered shape is provided at the periphery of the flat mirror.
