Patent ID: 8796011

Claim:
An apparatus for fabricating a biochip, the apparatus comprising: a reaction chamber which encapsulates the biochip to be sealed from an external environment; an exposure system which has a light source and a spatial light modulator, the spatial light modulator receives light from the light source and forms an optical image utilizing the received light, the optical image being received by the biochip; a detection system which detects light proceeding from the biochip; an optical path changing unit comprising a polarizing beam splitter which is disposed between the light source and the spatial light modulator; a polarizer which is disposed between the light source and the polarizing beam splitter; and a quarter-wavelength plate which is disposed between the polarizing beam splitter and the spatial light modulator; and a distortion correction device disposed between the polarizing beam splitter and the reaction chamber, wherein the distortion correction device comprises a deformable mirror having a reflective surface which is deformable in response to at least one of mechanical and electrical manipulation for correcting distortion of the optical image.
