Abstract:
The present invention relates to an alkali-free glass substrate, having a difference Δn between the maximum value and the minimum value of a refractive index at a cross-section of a glass sheet of 0.40×10 −5  or less. According to the alkali-free glass substrate of the present invention, the polishing ability can be extremely improved and the polishing time is shortened, so that the production efficiency can be improved.

Claim (Index 4):
The alkali-free glass substrate according to  claim 1 , wherein undulation height on both main surfaces of the alkali-free glass substrate in terms of undulation at a 20 mm pitch is 0.13 \u03bcm or less.
