Short test sample description:
PELCO® Sapphire Substrate Discs Size:Ø25.4mm x 0.5mm The divalent cation method forDESCRIPTION The PELCO Sapphire Discs or Wafers are made from high purity clear sapphire (Al2O3), ground and optically clear polished on both sides. Sapphire has a wide transmission range; from 150 to 6000nm with low absorbance in the 300 to 4500nm range. The discs are ideal as substrates for thin film research and are suitable for optical research. Excellent resistance against a wide range of chemicals. Surface polish to one microinch or better on
