Abstract
A flash device includes a micro-optic array for concentrating light from the flash lamp on a radiation-absorbing dye carrier, thereby sublimating or vaporizing the dye from the radiation-absorbing dye carrier onto a receiver element, e.g. a glass plate or the like.
Claims8
A flash device for transferring dye from a radiation-absorbing dye carrier to a receiver element, said flash device comprising:
- (i) a flash lamp providing a high energy flash of light;
- (ii) a reflector directing the light from said flash towards the receiver element;
- (iii) a support means for supporting the radiation-absorbing dye carrier between said reflector and the receiver element;
- and
- (iv) a micro-optics array located between said reflector and the radiation-absorbing dye carrier, said micro-optics array including a plurality of miniature lenses having optical power and located so as to concentrate the light directed by said reflector on the dye carrier.
A flash device for transferring dye from a radiation-absorbing dye carrier to a receiver element, said flash device comprising:
- (i) a flash lamp providing a high energy flash of light;
- (ii) a reflector directing the light from said flash towards the receiver element;
- (iii) a support means for supporting the radiation-absorbing dye carrier between said reflector and the receiver element;
- and
- (iv) a micro-optics array located between said reflector and the radiation-absorbing dye carrier, said micro-optics array including a plurality of miniature lenses concentrating the light directed by said reflector on the dye carrier, said plurality of miniature lenses being adapted to focus light rays to a plurality of focal points, wherein said plurality of miniature lenses include diffractive lens elements.
A flash device for transferring dye from a radiation-absorbing dye carrier to a receiver element, said flash device comprising:
- (i) a flash lamp providing a high energy flash of light;
- (ii) a reflector directing the light from said flash towards the receiver element,
- (iii) a support means for supporting the radiation-absorbing dye carrier between said reflector and the receiver element;
- and
- (iv) a micro-optics array located between said reflector and the radiation-absorbing dye carrier, said micro-optics array including a plurality of miniature lens elements concentrate the light directed by said reflector on the dye carrier, wherein said plurality of miniature lens elements are adapted to focus light rays to a plurality of focal points, and wherein said miniature lens elements have both a refractive and a diffractive optical power.
A color filter array manufacturing system comprising:
- (i) a flash lamp providing a high energy flash of light;
- (ii) a reflector directing the light from said flash towards a receiver element;
- (iii) a support means for supporting the radiation-absorbing dye carrier between said reflector and the receiver element;
- (iv) a micro-optics array located between said reflector and the dye carrier, said micro-optics array including a plurality of miniature lenses concentrating the light directed by said reflector on the dye carrier;
- and
- (v) a positioning system, said positioning system positioning the receiver element in a different position from a previous position of the receiver element prior to transferring an additional color dye onto the receiver element.
A color filter array manufacturing system comprising:
- (i) a flash lamp providing a high energy flash of light;
- (ii) a reflector directing the light from said flash towards a receiver element;
- (iii) a support means for supporting the radiation-absorbing dye carrier between said reflector and the receiver element;
- (iv) a micro-optics array located between said reflector and the dye carrier, said micro-optics array including a plurality of miniature lenses with optical power so as to concentrate the light directed by said reflector on the dye carrier;
- and
- (v) a positioning system, said positioning system positioning the micro-optic array in a slightly different position with respect to the receiver element, prior to transferring an additional color dye onto the receiver element.
