The invention discloses a sealed cabin perspective window. The sealed cabin perspective window comprises a bottom frame part, perspective glass, and sealing rings, pressing rings and fasteners respectively arranged on two sides of the perspective glass. The bottom frame part is a support which is used for fixing the cabin body and is provided with a groove. The sealing rings are arranged in two sides of the perspective glass and are pressed into the groove through the pressing rings. The fasteners are fixed to the bottom frame part through threaded holes evenly arranged on the bottom frame part. The invention also discloses a use of the sealed cabin perspective window. The sealed cabin perspective window has pressure resistance, heat resistance and high light transmittance. A test result shows that a device measurement accuracy error shown by a theodolite is within 5s. The sealed cabin perspective window satisfies the existing requirements on an installation precision of a spacecraft product.
