The present invention relates to an optical component having a crosslinked anti-fog coating obtainable by covalent attachment of a silane derivative of the formula (2) to the surface of the optical component and crosslinking of adjacent molecules:RXSiB&#x2003;&#x2003;(2)whereinm=1 to 3, n=1 or 2 and o=0 or 1, with the proviso that m+n+o=4;the radical X is selected from halogen or C-alkoxy, andfor m=2 or 3 the individual radicals X may be identical or different,the radical R is C-alkyl,the radical B has the structure -B1-B2, in which -B2 is a terminal hydrophilic group which is crosslinked to at least one hydrophilic group of an adjacent molecule of the anti-fog coat, and -B1- represents either a spacer group, which joins the hydrophilic group B2 to the Si atom, or a covalent bond,where the terminal hydrophilic group -B2 is poly(meth)acrylate, and for n=2 the individual radicals B may be identical or different.

Anti-fog coating

A spectacle lens having a front surface intended to be fitted away from the eye. The spectacle lens includes a substrate made from mineral glass or an organic material. The spectacle lens has selective light wavelength filter properties. The selective light wavelength filter properties include a spectral transmittance between 80% and 95% for all wavelengths in a wavelength range between 428 nm and 452 nm for a light ray entering the spectacle lens on the front surface at an angle of incidence of 0&#xb0;, a spectral transmittance between 95% and 100% for all wavelengths in a wavelength range between 500 nm and 700 nm for a light ray entering the spectacle lens on the front surface with an angle of incidence of 0&#xb0; and a yellowness index of no more than 10 for a standard illuminant D65 and a standard observer function of 2&#xb0; (D65/2&#xb0;).

An optical element has a substrate body made from transparent plastic and a coating having multiple layers. The coating includes a hard lacquer layer adjoining the substrate. The coating has a diffusivity ensuring the absorption of water molecules passing through the coating in the substrate and the release of water molecules from the substrate through the coating from an air atmosphere on that side of the coating facing away from the substrate with a flow density which, proceeding from the equilibrium state of the quantity of water molecules absorbed in the substrate in an air atmosphere at 23&#xb0; C. and 50% relative humidity, brings the setting of the equilibrium state of the quantity of water molecules absorbed in the substrate in an air atmosphere at 40&#xb0; C. and 95% relative humidity within an interval not more than 10 h longer than for setting this equilibrium under corresponding conditions with an identical uncoated substrate.

Optical element having a coating of high diffusivity

An optical component having an anti-fog coating obtainable by covalent attachment of a silane having the formula (1): RXSiAto the surface of the optical component. The covalent attachment of the compound of the formula (1) to the surface of the optical component is accomplished by reacting at least one of the reactive, hydrolyzable &#x2014;Si&#x2014;X&#x2014; groups with a suitable reactive surface group, for example, an &#x2014;OH group, to form &#x2014;Si&#x2014;O&#x2014;.

A projection objective is disclosed. The projection objective can include a plurality of optical elements arranged to image a pattern from an object field in an object surface of the projection objective to an image field in an image surface of the projection objective with electromagnetic operating radiation from a wavelength band around an operating wavelength &#x3bb;. The plurality of optical elements can include an optical correction plate that includes a body comprising a material transparent to the operating radiation, the body having a first optical surface, a second optical surface, a plate normal substantially perpendicular to the first and second optical surfaces, and a thickness profile defined as a distance between the first and second optical surfaces measured parallel to the plate normal. The first optical surface can have a non-rotationally symmetric aspheric first surface profile with a first peak-to-valley value PV&#x3e;&#x3bb;. The second optical surface can have a non-rotationally symmetric aspheric second surface profile with a second peak-to-valley value PV&#x3e;&#x3bb;. A thickness of the optical correction plate can vary by less than 0.1*(PV+PV)/2 across the optical correction plate.
