Title: Aperture and optical scanning microscope using the aperture
Inventor: FUKUZAWA KENJI
IPC: G02F1/19
Filed: 1989-10-23
Abstract: PURPOSE:To obtain the aperture which facilitates manufacture and erasure, and optical axis alignment and to the optical scanning microscope which uses it by forming the aperture of a material whose complex refractive index is controllable with a light beam. CONSTITUTION:The aperture is formed of the material whose complex refractive index can be controlled with the light beam. For example, a material which is low in reflection factor and decreases in the imaginary part of the complex refractive index by light irradiation, namely, decreases in absorptivity by the light irradiation and also varies in refractive index reversibly is used for an aperture forming film 11. When this aperture forming film 11 is irradiated with a light spot 12 which has a Gaussian distribution, the transmissivity decreases with the distance from the center of the light spot, the same effect with an aperture 13 whose aperture diameter is smaller than the light spot diameter is obtained, and the aperture can be erased. Consequently, the formation and erasure, and optical axis alignment of the aperture are facilitated and when this aperture is used for the optical scanning microscope, a high- resolution, simple device is obtained.
