Ambient and elevated temperature biaxial flexural strength were measured for polished sapphire windows. Tested for comparison were windows given an SiO or glaze surface treatment. Infrared transmittance and visible imaging quality were unaffected by surface treatment while significant increases in strength and thermal‐shock resistance resulted.
