An optical sheet includes a sheet-like body portion, and unit prisms arranged on one surface of the body portion. Each unit prism extends linearly in a direction intersecting the arrangement direction. Each unit prism, when viewed in a direction parallel to the arrangement direction of the unit prisms, has an uneven polygonal-line-shaped contour and, with reference to raised portions defined by the polygonal-line-shaped contour of each unit prism, the distance between a top of each raised portion, a farthest point from the body portion in the raised portion, and the body portion in the normal direction of the body portion is not constant. The optical sheet can prevent significant problems when it is superimposed on another member.

A vibration isolator having an inner passage of a communication tube that communicates the negative pressure chamber with the valve chamber. A pipe connection part and a supply/discharge pipe communicate the valve chamber with the supply/discharge port of a switching valve on the outside of the vibration isolator. The switching valve selectively communicates the supply/discharge port to either an intake manifold as the negative pressure supply source, or an atmosphere space. The negative pressure chamber communicates with the valve chamber through the communication tube on the inner peripheral side of the outer cylinder member. Thus, either of a negative pressure and an atmospheric pressure, which is same as a pressure in the valve chamber, can be supplied into the negative pressure chamber, by supplying either of the negative pressure and the atmospheric pressure into the valve chamber through the supply/discharge pipe and the pipe connection part.

The present invention aims at providing a glass substrate required to have a surface polished with extremely high accuracy as in glass substrates for reflective masks for use in EUVL; and a polishing method for producing the glass substrate. The present invention provides a glass substrate for mask blank, which is a glass substrate comprising SiO2 as a main component and having a polished main surface, wherein concave defects and convex defects on the main surface have a depth of 2 nm or smaller and a height of 2 nm or smaller, respectively, and have a half-value width of 60 nm or smaller, so that the concave defects and/or the convex defects do not cause phase defects when the glass substrate is used to produce a mask for exposure and the mask is used. Also disclosed are a polishing method for producing the glass substrate, and a mask blank and a mask for exposure using the glass substrate.
