A methodof manufacturing a (part of) color ring is provided. The color ring converts a color of light emitted by a light emitter into at least one other color. The method () comprising the steps of: i) pressing () a first ring body of a first granulated precursor comprising a first luminescent material for converting the color of the light of the light emitter into a first one of the at least one other color, and ii) sintering () the first ring body for obtaining a first ceramic ring. The color ring comprises at least a segment of the first ceramic ring. Further, the method may comprises the steps of: iii) pressing () a second ring body of a second granulated precursor, wherein the first luminescent material is absent, iv) sintering () the second ring body for obtaining a second ceramic ring, v) segmenting () the first ceramic rings in at least two parts and segmenting () the second ceramic ring in at least two parts, and vi) forming () at least a part of the color ring by coupling a part of the first ceramic ring and a part of the second ceramic ring.

The invention relates to the field of laser sources (), and for specifically to inhibiting damage due to misuse of a laser source (), in particular of a high-power laser source () provided in a consumer product (). The proposed device () includes at least a laser source () and a safety unit (), wherein by means of the arrangement of the safety unit () it is provided that potential harm caused by misuse of the laser source () based on an unauthorized access to the laser source () is confined or even prevented by reducing the power level of the output of the laser source () or by even completely stopping any laser output therefrom. A corresponding method of providing a laser source () and a further method of preventing misuse of a laser source () are also proposed.

A method of irradiating to pattern a photosensitive layer such as a resist (L) immersed in a fluid (L), involves applying a removable transparent layer (L, L), projecting the radiation onto the resist through the immersion fluid and through the transparent layer, such that imperfections in the fluid are out of focus as projected on the surface, and subsequently removing the transparent layer. The transparent layer can help distance such imperfections from the focus of the radiation on the surface and so can reduce or eliminate shadowing. Hence the irradiation can be more complete, and defects reduced. It can be particularly effective for imperfections in the form of small bubbles or particles in the immersion fluid especially at the fluid/surface interface for example. The radiation can be for any purpose including inspection, processing, patterning and so on. The removal of the transparent layer can be combined with a step of developing the resist layer.
