摘要： PURPOSE:To provide a simple thin film responding to ultraviolet rays with an improved light resistance and repetition property by developing a coloring phenomenon by causing ion dissociation by absorbing ultraviolet rays. CONSTITUTION:A glass substrate 11 with ITO thin film 12 as a light transmission electrode is used as a support for supporting a thin-film element and then a macromolecular gel (chemical 1) with a leuco coloring matter part causing ion dissociation by absorbing the light in ultraviolet ray region with a wavelength of 499nm or smaller is formed on the support layer by the blade coating or spin coating method. A glass substrate 15 with ITO thin film 14 is brought into contact with the macromolecular gel layer 13 opposingly so that no clearance such as air bubbles is not generated and the thickness of the macromolecular gel layer is adjusted by a spacer 17. Further, its outside periphery is sealed with a sealing agent.

摘要： PURPOSE:To enable a position and a radius of a laser beam waist to be measured readily and highly accurately by providing a secondary high harmonic generator, a means for moving the secondary high harmonic generator in an advancing direction of the laser beam, a harmonic separator for separating a fundamental harmonic of laser beam from a secondary high harmonic, and a photo sensor. CONSTITUTION:When a laser beam 8 is converged by a lens 5 and impinges on a secondary high harmonic generator 1, a secondary high harmonic is generated along with a fundamental harmonic and passes through a harmonic separator 4 which shields the fundamental harmonic and then light intensity of the secondary high harmonic is received by a photo sensor 3. The secondary high harmonic generator 1 is scanned in an advancing direction of the laser beam and a relationship between an output signal from the photo sensor 3 and a displacement of the secondary high harmonic generator is displayed on a recorder 7.
