Definitions
- the invention relates to a light source with a microstructured optical element that spectrally broadened the light from a primary source, and with an optic that forms the spectrally broadened light into an illuminating light beam.
- the invention relates to a microscope that includes a light source with a microstructured optical element that spectrally broadens the light from a primary source and with optics that form the spectrally broadened light into an illuminating light beam.
- the patent US 6,097,870 discloses an arrangement for generating a broadband spectrum in the visible and infrared spectral range.
- the arrangement is based on a microstructured fiber into which the light from a pump laser is coupled.
- the pump light is broadened in the microstructured fiber by nonlinear effects.
- So-called photonic band gap material or "photon crystal fibers”, “holey fibers” or “microstructured fibers” are also used as microstructured fibers. Refinements are also known as so-called “hollow fibers”.
- Another arrangement for generating a broadband spectrum is shown in US Pat Publication by Birks et al .: “Supercontinuum generation in tapered fibers", Opt.Lett. Vol. 25, pJ415 (2000).
- a conventional optical fiber with a fiber core is used which has a taper at least along a section
- Optical fibers of this type are known as so-called “tapered fibers”.
- Biological tissue or, for example, prepared with fluorescent dyes are used as samples
- the illuminating light reflected from the sample is often detected, and solid-state lasers and dye lasers, as well as fiber lasers and optical parametric oscillators (OPO), which are preceded by a pump laser, are also frequently used.
- OPO optical parametric oscillators
- the object is achieved by a light source which is characterized in that the optics compensate for the different divergences of the spectral components of the spectrally broadened light.
- the light source according to the invention advantageously generates an illuminating light beam, the light of which can be collimated simultaneously for all of its spectral components. This has an extremely favorable effect, particularly in scanning microscopy, since it is of crucial importance that all spectral components of the illuminating light beam find their focus in the sample plane to be observed.
- the optics have a different focal length for light-different wavelengths. It is sufficient for many applications that the optics take into account and correct a linear dependence of the divergence on the wavelength in the first order. For highly specialized applications, the optics are preferably adapted exactly to the spectral properties of the microstructured fiber.
- the optics focus the shorter-wave spectral components of the spectrally broadened light more than the longer-wave spectral components of the spectrally broadened light.
- the microstructured optical element preferably contains photonic band-gab material and is additionally preferably configured as an optical fiber (photonic crystal fiber PCS; Holey fiber, etc.).
- the microstructured optical element designed as an optical fiber has a tapered fiber.
- an aperture is provided which blocks out the marginal rays of the spectrally broadened light.
- This aperture takes into account the effect that, with increasing wavelength, more light enters the cladding of the microstructured optical fiber, which is visible at the output of the microstructured optical fiber, even though the light output portion of this light is significantly less than that of the spectrally broadened, which emerges directly from the core light.
- the optics preferably have the spectrally broadened light Illumination light beam forms a suitable aperture.
- the optics are part of a microscope, in particular a scanning microscope or a confocal scanning microscope. It is particularly advantageous if the optics are designed as lenses.
- the light source according to the invention can also be used, for example, in a flow cytometer or an endoscope or a chromatograph or a lithography device.
- the microstructured optical element is constructed from a multiplicity of microoptical structural elements which have at least two different optical densities.
- the optical element includes a first region and a second region, the first region having a homogeneous structure and a microscopic structure formed from micro-optical structure elements in the second region. It is also advantageous if the first area encloses the second area.
- the micro-optical structural elements are preferably cannulas, webs, honeycombs, tubes or cavities.
- the microstructured optical element consists of glass or plastic material and cavities arranged side by side.
- the variant in which the microstructured optical element consists of photonic band gap material and is designed as an optical fiber is particularly preferred.
- An optical diode is preferably provided between the laser and the optical fiber, which suppresses back reflections of the light beam which originate from the ends of the optical fiber.
- a very particularly preferred and easy-to-implement embodiment variant includes, as a microstructured optical element, a conventional optical fiber with a fiber core diameter of approximately 9 ⁇ m, which has a taper at least along a section.
- Optical fibers of this type are known as so-called “tapered fibers”.
- the optical fiber is a total of 1 m long and has a taper over a length of 30 mm to 90 mm.
- the diameter of the entire fiber in the region of the taper is approximately 2 ⁇ m.
- Fig. 2 shows the beam path of spectrally broadened light without
- FIG. 5 shows a further light source according to the invention and FIG. 6 shows a confocal scanning microscope according to the invention.
- the microstructured optical fiber 5 widens the light 7 of a primary light source 9, which is designed as a pulse laser 11.
- a primary light source 9 which is designed as a pulse laser 11.
- an optical system 13 which forms the spectrally broadened light into an illuminating light beam 15, the optical system 13 compensating for the different divergences of the spectral components of the spectrally broadened light which emerges from the microstructured optical fiber 5.
- a focusing optics 17 which focuses the light of the primary light source onto the entry end of the microstructured optical fiber 5.
- the components are located in a housing 19. 2 shows an example of the course of a first light bundle 21 from the red spectral range and a second light bundle 23 from the blue spectral range of the spectrally broadened light as it emerges from a microstructured optical fiber 5.
- the microstructured optical fiber 5 has a cladding 25 and a fiber core 27 , It can also be seen schematically that the first light bundle 21 partly exits from the red spectral range from the cladding 25, while the second light bundle 23 essentially emerges from the fiber core from the blue spectral range.
- the optics preferably also compensate for this fact of afocality.
- FIG. 3 shows an arrangement according to the prior art, in which the optics 13 are designed as achromatic optics 29 for shaping an illuminating light beam 15. While the second light bundle 23, which contains light from the blue spectral range, is collimated by the achromatic optics 29, the light from the first light bundle 21, which contains light from the red spectral range, is disadvantageously focused. The two light beams 21, 23 consequently do not simultaneously form a parallel beam and therefore only an illuminating light beam of reduced optical beam quality.
- FIG. 3 shows an arrangement according to the prior art, in which the optics 13 are designed as achromatic optics 29 for shaping an illuminating light beam 15. While the second light bundle 23, which contains light from the blue spectral range, is collimated by the achromatic optics 29, the light from the first light bundle 21, which contains light from the red spectral range, is disadvantageously focused. The two light beams 21, 23 consequently do not simultaneously form a parallel beam and therefore only an illuminating light beam of reduced optical beam quality.
- FIG. 4 illustrates the course of the first light bundle 21, which contains light from a red spectral component, and of the second light bundle 23, which contains light from a blue spectral component, when using an optical system 13, which performs optical system 31 that is matched to the spectral properties of the microstructured optical optical fiber 5 is.
- both the first light bundle 21, which contains light from the red spectral range of the spectrally dispersed light, and the light of the second light bundle 23, which contains light from the blue spectral range of the spectrally broadened light run collimated parallel to one another and form one Illuminating light beam with perfect optical beam properties.
- FIG. 5 shows an embodiment variant of the light source in which a variable diaphragm 33 is provided in order to block out the light emerging from the cladding 25 of the microstructured optical element 3.
- FIG. 6 shows a scanning microscope according to the invention, which is designed as a confocal scanning microscope.
- the illuminating light beam 15 emanating from a light source 1 with a microstructured optical element not shown in this figure is focused by the lens 35 onto the illuminating pinhole 37 and then arrives at the main beam splitter 39, which directs the illuminating light beam 15 to the beam deflecting device 41, which has a gimbal-mounted scanning mirror 43 includes, directs.
- the beam deflection device 41 guides the illuminating light beam 15 through the scan lens 45 and the tube lens 47 as well as through the objective 49 over or through the sample 51.
- the detection light 53 emanating from the sample arrives in the reverse light path , namely through the lens 49, the tube lens 47 and through the scan lens 45 back to the beam deflection device 41 and to the main beam splitter 39, passes this and after passing through the detection pinhole 55 reaches the detector 57, which is designed as a multiband detector 59.
- the detection light is detected in various spectral detection channels and electrical signals proportional to the power are generated, which are forwarded to a processing system (not shown) for displaying an image of the sample 51.
