Abstract: An optical test system includes a stage region to accommodate an object to be tested, a first incident optical system which changes a first polarization state of a first light beam to a second polarization state and provide the first light beam in the second polarization state to the stage region in a first direction at a first incident angle which is not a right angle, a second incident optical system which changes a third polarization state of a second light beam to a fourth polarization state and inputs the second light beam in the fourth polarization state to the stage region in a second direction at a second incident angle which is not a right angle, and a main optical system to detect a first reflected light beam reflected from the stage region at a first reflection angle different from the first and second incident.

Abstract: Provided is a hyperspectral imaging (HSI) apparatus. The HSI apparatus includes: a first slit plate configured to introduce an output beam; a first aspherical mirror configured to reflect the introduced output beam; a first grating having a planar reflective surface, the first grating configured to generate a plurality of first split beams by splitting the output beam after being reflected by the first aspherical mirror; and a first camera configured to detect the plurality of first split beams.

Abstract: A thin-film deposition apparatus includes: a housing; a chamber located within the housing and providing an internal space; a platform disposed within the chamber and configured to support a substrate; a reflector disposed within the housing and disposed outside the chamber; a light source disposed between opposing walls of the reflector and configured to radiate light onto the substrate; a light receiver disposed within the housing, spaced apart from the light source with a portion of the reflector therebetween, and having a hole through which light emitted from the substrate is introduced; an optical cable connected to the light receiver and extending to the outside of the housing; and a sensor disposed outside the housing, connected to the optical cable, and configured to measure a temperature of the substrate by analyzing light transmitted from the optical cable.
