Abstract: Disclosed are herein an apparatus and method for extreme ultraviolet (EUV) spectroscope calibration. The apparatus for EUV spectroscope calibration includes an EUV generating module, an Al filter, a diffraction grating, a CCD camera, a spectrum conversion module, and a control module that compares a wavelength value corresponding to a maximum peak among peaks of the spectrum depending on the order of the EUV light converted from the spectrum conversion module with a predetermined reference wavelength value depending on an order of high-order harmonics to calculate a difference value with the closest reference wavelength value, and controls the spectrum depending on the order of the EUV light converted from the spectrum conversion module to be moved in a direction of wavelength axis by the calculated difference value. Thus, it is possible to accurately measure a wavelength of a spectrum of EUV light used in EUV exposure technology and mask inspection technology.

Abstract: Provided is a cell-level retinal disease detection apparatus including a light imaging means configured to emit light to an eyeball and a light processing means which receives light reflected by the eyeball and processes and compensates light for an astigmatism aberration thereof which occurs at the eyeball to compensate. Here, the light processing means includes a wavefront sensor which senses the astigmatism aberration of the reflected light which occurs due to the eyeball and a light compensation mirror which compensates the light based on the sensed astigmatism aberration, and compensates for a difference in the astigmatism aberration to detect a disease of a retina of the eyeball.
