Abstract | A target assembly, comprising:a dichroic coating (406) deposited on a substrate (402); a buffer layer (416) deposited on the dichroic coating (406); and a wavelength converter (408) having a bonding surface that is bonded to the buffer layer (416) by a layer of low temperature glass (410), the buffer layer (416) acting to prevent a reaction between the layer of low temperature glass (410) and the dichroic coating (406), the layer of low temperature glass (410) extending at least over an entirety of the bonding surface of the wavelength converter (408), the wavelength converter (408) comprising a phosphor for converting a primary light from an excitation source into a secondary light and the dichroic coating (406) reflecting at least 50% of the secondary light emitted by the wavelength converter (408).
L'invention concerne un ensemble cible comprenant : un revêtement dichroïque (406) déposé sur un substrat (402); une couche tampon (416) déposée sur le revêtement dichroïque (406); et un convertisseur de longueur d'onde (408) ayant une surface de liaison qui est collée à la couche tampon (416) par une couche de verre basse température (410), la couche tampon (416) agissant pour empêcher une réaction entre la couche de verre basse température (410) et le revêtement dichroïque (406), la couche de verre basse température (410) s'étendant au moins sur la totalité de la surface de liaison du convertisseur de longueur d'onde (408), le convertisseur de longueur d'onde (408) comprenant un photophore pour convertir une lumière primaire provenant d'une source d'excitation en une lumière secondaire, et le revêtement dichroïque (406) réfléchissant au moins 50 % de la lumière secondaire émise par le convertisseur de longueur d'onde (408). |
