Abstract: An ND filter of a thin film type is formed on a transparent substrate, such that a light-absorbing film and a dielectric film are laminated on the transparent substrate. The transparent substrate is formed of a resin film which can be fed at a constant speed. The light-absorbing film is deposited by sputtering a target material comprised of a metal or a mixture of a metal and a metal oxide onto the resin film traveling at the constant speed while using a mixture gas of oxygen, nitrogen, and argon as an ambient gas. Consequently, the light-absorbing film is composed of a mixture of the metal and metal compounds, and has an extinction coefficient of 0.3 or more in a visible wavelength range. Typically, the light-absorbing film is composed of 1% through 50% by weight of the metal, 30% or more by weight of saturated metal oxide, and residual components composed of the compounds of the metal containing lower oxide and nitride of the metal.

Abstract: An ND filter is composed of a transparent substrate, a laminate of a light-absorbing film and a dielectric film formed on the transparent substrate, and a carbon film formed to clad a surface of the laminate of the light-absorbing films and the dielectric films. Depending on cases, another carbon film is also formed on a reverse side of the transparent substrate. The carbon film is formed by a deposition process at a deposition temperature ranging from a room temperature to 150° C. The light-absorbing film is formed of a mixture of metal and compound thereof, a material of the metal being selected from a group consisting of Ti, Cr, Ni, NiCr, NiFe, and NiTi. The dielectric film is formed of SiO2 or Al2O3.

Abstract: A thin film type ND filter being inexpensive and excelling in durability. There is provided ND filter (0) comprising transparent substrate (1) and, superimposed thereon, light absorption films (3,5) and dielectric films (2,4,6), wherein the light absorption films 3.5 consist of a composition comprising 1 to 30 wt. % of a metal in pure form and 50 wt. % or more of a saturated oxide of the metal with the balance of compounds of the metal containing lower oxides of the metal. Metal raw material of the light absorption films (3,5) is selected from among Ti, Cr, Ni, NiCr, NiFe and NiTi. As for the dielectric films (2,4,6), SiO2 or Al2O3 is used. Function of reflection prevention is imparted by superimposing the light absorption films (3,5) and dielectric films (2,4,6) in predetermined film thicknesses and in predetermined sequence. Alternatively, a reflection prevention layer may be formed on the back of the substrate (1).

Abstract: An ND filter is made of a transparent substrate having a plane. An optical film is formed on the plane of the transparent substrate. The optical film has a lamination structure including a light absorption film and a dielectric film, and has a variable transmission density. A thickness of either the light absorption film or the dielectric film of the lamination structure is changed in an in-plane direction of the transparent substrate so that the transmission density of the optical film is controlled to vary in the in-plane direction. The light absorption film is composed of a material selected from Ti, Cr, Ni, NiCr, NiFe, NiTi and a mixture thereof, and the dielectric film is formed of SiO2, Al2O3 or a compound thereof.

Abstract: A neutral density filter has a multi-layer structure of thin films laminated on a substrate made of a transparent material. The multi-layer structure contains a transparent thin film composed of a dielectric material effective to transmit the incident light and a non-transparent thin film effective to absorb a part of the incident light. The non-transparent thin film is composed of a metal material which is deposited by vacuum evaporation. The non-transparent thin film contains an oxide of the metal material, which is generated during the vacuum evaporation by introducing a gas containing an oxygen while maintaining a vacuum degree in a range of 1×10−3Pa to 1×10−2Pa, and which is deposited concurrently with the metal material.
