Thermal imprinting of transparent tin phosphate glass was performed at 250 ° C using a fine-patterned silica mold. The glass sample was prepared by a conventional melt-quenching method and polished with a roughness of 10 nm for imprinting experiments. The imprinting temperature is optimized based on experimental viscosity data. Scanning electron microscope and atomic force microscope observations revealed that a square grid pattern has a surface roughness of 10 nm and 5 μ m × 5 μ m squares with 1 μ m intervals and 90 100 nm depth. Diffraction spots due to the micropattern are demonstrated by illuminating He–Ne laser light.
