PROBLEM TO BE SOLVED: To provide a light selective transmission filter which selectively shields light, has a high transmittance of light at a specific wavelength such as visible rays, moreover, has a sufficiently reduced thickness and, even when being sufficiently thin, is excellent in heat resistance, and to provide a lens unit having the same filter. SOLUTION: The light selective transmission filter selectively reduces the transmittance of light, wherein the thickness thereof is less than 200μm and the base material thereof includes a functional film with reflow resistance. The present invention also provides a lens unit having such a light selective transmission filter and a lens. COPYRIGHT: (C)2008,JPO&INPIT |
