摘要:
Provided is an optical system for a thermal image microscope. The optical system includes an image forming unit and a relay unit. The image forming unit forms a focus. The relay unit elongates an optical path. Here, the image forming unit includes six lenses. The relay unit includes two lenses. Aspherical surfaces of the lenses are all convex surfaces.

Disclosed is a method for preparation of a liquid crystal film having uniaxial alignment, comprising steps of: elevating temperature of a substrate coated with a nanostructure formed of liquid crystal molecules to a value sufficient to alter the nanostructure into a liquid phase; and decreasing the temperature to another value sufficient to again alter the liquid phase into a liquid crystal phase in the presence of a magnetic field to horizontally align the nanostructure of liquid crystal molecules.

Provided is an apparatus for controlling temperature of a black body. The apparatus includes a black body emitting radiant energy of infrared rays; a first Peltier element adjacent to the black body, the first Peltier element having a 1a surface and a 1b surface that selectively emit or absorb heat; a copper plate adjacent to the 1b surface; a second Peltier element adjacent to the 2b surface, the second Peltier element having a 2a surface and a 2b surface that selectively emit or absorb heat; a heat transfer member comprising a bent surface adjacent to the 2a surface, and an arm extending toward both ends of the black body to be adjacent to the both ends of the black body and a control unit controlling the 2a surface to emit heat when the 1a surface emits heat, and the 2a surface to absorb heat when the 1a surface absorbs heat.
