A method of making a mirror substrate for a vehicular mirror assembly includes providing a glass substrate and fixturing the glass substrate at a fixture to support the glass substrate. A rotatable grinding wheel is presented to the front perimeter portion of the glass substrate and the front perimeter portion of the glass substrate is ground to establish a ground rounded surface about and around the periphery of the glass substrate. After grinding the front perimeter portion of the glass substrate to establish the ground rounded surface, a rotatable polishing wheel is presented to the ground rounded surface and the ground rounded surface is polished to establish a polished rounded surface about and around the periphery of the glass substrate. The polished rounded surface provides a smooth transition between the front surface of the glass substrate and a rear portion of the circumferential perimeter edge of the glass substrate.

An interior rearview mirror assembly includes a mirror casing and a prismatic reflective element. The mirror casing is a unitarily molded mirror casing having at least one attachment surface. The prismatic reflective element includes a glass substrate having a front surface and a rear surface and a perimeter edge about a periphery of the glass substrate. A mirror reflector is established at the rear surface of the glass substrate. The perimeter edge of said glass substrate has a generally rounded surface disposed between the front surface and the mirror casing. The prismatic reflective element is attached at the attachment surface of the mirror casing. The perimeter edge of the glass substrate is exposed to and is viewable by the driver of the vehicle when the interior rearview mirror assembly is normally mounted in the vehicle.

The invention relates to a method for producing an anti-reflection surface on an optical element, said method comprising the following steps: a) the optical element is prepared; b) uncharged, spherical, micellar polymer units comprising an inner core region and an outer shell region are prepared; and c) at least one region of the surface of the optical element is coated with polymer units in such a way that the polymer units are essentially regularly dispersed in a film-type layer over the surface of the optical element. The invention also relates to an optical element having an anti-reflection surface (28a, 28b, 28c) comprising spherical micellar polymer units (16a, 16b, 16c) having an inner core region (18) and an outer shell region (20) and being essentially regularly dispersed in a film-type layer (26a, 26b, 26c) over the surface of the optical element (22). The invention further relates to an optical element having an anti-reflection surface (34, 34a) comprising metal clusters (32, 32a) and/or metal oxide clusters (38, 38) which are essentially regularly distributed over the surface of the optical element (22).

A laser processing method where laser beam for processing is irradiated on a processing object and the laser beam for processing directly removes a part of the processing object. The processing object is made of a glass substrate, metal thin film having high absorption to laser beam for processing is formed on a surface of glass substrate, into which laser beam for processing is made incident, the laser beam for processing is irradiated from a surface of metal thin film, and matter is directly removed by irradiation of laser beam onto the processing object in order to form a region finer than an irradiation region of laser beam for processing on the processing object.

This invention relates to a continuous process for producing a web of thin, chemically hardened glass that can be wound on a roll. The process comprises the steps of (i) drawing glass, containing original alkali ions, to form a web of glass having a thickness equal to or lower than 1.2 mm and having a first and second major surface; (ii) directly after or during said drawing, treating both said surfaces of said web with chemical hardening means during less than two hours, replacing said original alkali ions by alkali ions having a larger radius; and (iii) after treating both said surfaces, winding said web on a core.
