A light source capable of operating third and fourth reflection mirrors included in a beam splitting device in conjunction with movements of first and second reflection mirrors included in a beam transfer device and an optical assembly, respectively. The third and fourth reflection mirrors are disposed on optical paths of a pre-pulse and a main pulse emitted from first and second pulse generators, respectively. The light source operates the third and fourth reflection mirrors to offset an excessive compensation of the main pulse caused in a process of compensating for an optical path error of the pre-pulse. The light source may be included in an extreme ultraviolet light source system.

Light source and extreme ultraviolet light source system using the same

An extreme ultraviolet (EUV) collector inspection apparatus and method capable of precisely inspecting a contamination state of an EUV collector and EUV reflectance in accordance with the contamination state are provided. The EUV collector inspection apparatus includes a light source arranged in front of an EUV collector to be inspected and configured to output light in a visible light (VIS) band from UV rays, an optical device configured to output narrowband light from the light, and a camera configured to perform imaging from an UV band to a VIS band. An image by wavelength of the EUV collector is obtained by using the optical device and the camera and a contamination state of the EUV collector is inspected.

Extreme ultraviolet (EUV) collector inspection apparatus and method

A fuel cell separator includes a metal substrate having a surface; an ion penetration layer including carbon diffusion-inhibiting ions extending from the surface of the metal substrate into the metal substrate; and a carbon coating layer disposed on the surface of the metal substrate.

Fuel cell separator and coating method for fuel cell separator

A separator for a fuel cell includes: a metal base material; and a carbon coating layer formed on one surface or both surfaces of the metal base material, in which roughness Ra formed at an interface between the metal base material and the carbon coating layer may be in a range of 20 to 78 nm.

Separator for fuel cell and coating method thereof
