The value of reflectance in case there is the minimum
value at specific wavelength in visible light range. |

UV ray has wavelength of about 400nm or less and makes
organic matters damaged. Therefore, an UV cut function is necessary
to protect works of art etc. |
| 23 |

Reciprocal of the radiant energy of each light which
looks the same brightness in changing wavelength. It shows the relation
of the sensitivity of brightness and the energy of light. |
| 24 |

A method for depositing a layer of metallic and/or nonmetallic
materials on substrate surface. The materials are evaporated in a
high vacuum and deposited on the surface. |
| 26 |

The method for forming a layer on a substrate. Atoms
and/or molecules on a substrate are evaporated by ion beam, and abrade
to the objective surface. |
| 27 |
spin coating |
A method for depositing a layer on substrate by rotating
basis material horizontally after applying a liquid on it. |
