    摘要: Disclosed is an object made of plastic material, in particular a plastic ophthalmic lens, colored with at least one photochromic substance which is also excited by light in the UV range of the spectrum and has a higher absorption in the excited state, judged by the spectral light sensitivity of the human eye, than in the not excited state and to which, in addition, at least one UV absorbing material is added in such a concentration that darkening of the photochromic substance(s) is independent of the UV fraction of the excitation light.But rather the intensity of the darkening depends on brightness, i.e. the intensity integrated over the spectral light sensitivity of the human eye V.sub.2.

    摘要: Disclosed is a scanning system havinga light source,a collimator lens,a scanning unit anda scanning objective. The present invention is distinguished by that for the correction of the chromatic aberration over a large wavelength range, only the transverse chromatic aberration of the scanning objective is corrected, and that the intersection lengths of the light rays having wavelengths in the wavelength range over which the scanning system is to be corrected chromatically is dimensioned after the collimator lens in such a manner that the longitudinal chromatic aberration of the scanning system is compensated as well.

    摘要: A uniform strength ophthalmic lens having a gradient refractive index changing rotational-symmetrically about the optical axis in which the curvature course of at least one of the two surfaces of the ophthalmic lens is selected without consideration of correction of aberration so that the critical thickness of the ophthalmic lens does not exceed a specific value and that the gradient refractive index is change rotational-symmetrically about the optical axis so as to correct the aberration. In this manner, a significant reduction of the critical thickness of the opthalmic lens, i.e., the center thickness is a positive lens and peripheral thickness in a negative lens, is achieved while providing an ophthalmic lens having good image-forming properties.

    摘要: A method for using mass-produced light-emitting diodes of a predetermined luminance in instruments requiring a precise luminance value and a light-emitting diode arrangement for adapting such mass-produced light emitting diodes to such instruments. The above-noted method includes the steps of disposing an LED in a lengthwise adjustable manner within a sleeve, closing the sleeve with a light diffusing disc at an end thereof from which the light from the LED is intended to merge and displacing the LED within the sleeve in such a manner that a precisely defined luminance appears at the diffused disc. In accordance with a preferred embodiment of the apparatus, a tubular sleeve of an elastic plastic material is provided with mounting threads at one end thereof for mounting same within a cap with a light-diffusing disc located between the threaded end of the sleeve and the cap. Additionally, the sleeve is provided with longitudinally extending beads within which electrical connectors of the LED can be mounted. The LED is positionally adjustable with respect to the diffusing disc by elastic deformation of the sleeve and is held in place at a position to which it is adjusted by the force produced by the sleeve at an area of localized elastic deformation adjacent the LED.
