Abstract
An illumination device for a microscope, in particular for an operation microscope, has a light source with an improved lifetime. The light source is in the form of a gas discharge lamp having a microwave generator, a microwave waveguide and an electrodeless bulb. The bulb contains a luminescent material and is coupled to the microwave waveguide so that microwaves can stimulate the luminescent material to emit light.
Claims20
An illumination device for a microscope, comprising:
- a bulb containing a luminescent material;
- a microwave generator;
- a microwave waveguide coupled between the bulb and the microwave generator so that radiation from the microwave generator received by the microwave waveguide and directed to the bulb stimulates the luminescent material to generate light without use of electrodes in the bulb;
- and
- optics that receive the light from the bulb and direct the light to an output.
2 more elements
A microscope, comprising:
- a gas discharge lamp;
- and
- optics that receive light from the lamp and direct the light to an object plane,
- wherein the gas discharge lamp comprises
- a bulb containing a luminescent material,
- a microwave generator, and
- a microwave waveguide coupled between the bulb and the microwave generator so that radiation from the microwave generator received by the microwave waveguide and directed to the bulb stimulates the luminescent material to generate the light without use of electrodes in the bulb.
4 more elements
A method of operating a microscope, comprising the steps of:
- providing a gas discharge lamp for a microscope having optics that receive light from the lamp and direct the light to an object plane, wherein the gas discharge lamp comprises a bulb that contains a luminescent material;
- generating microwave radiation external to the bulb;
- guiding the microwave radiation to the bulb so that the radiation stimulates the luminescent material to generate the light without use of electrodes in the bulb.
