a Pit count per unit area measured by AFM. These values were 5.26, 12.94, and 18.2 for fused silica, aluminosilicate, and borosilicate glasses, respectively. b Wavefront deviation after transmission from fused silica, aluminosilicate, and borosilicate substrates. The RMS values were 19.60, 79.34, and 149.26 nm for fused silica, aluminosilicate, and borosilicate glass, respectively. Additionally, the PV values were 101.3, 524, and 985.5 nm for fused silica, aluminosilicate, and borosilicate glasses, respectively
