Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a xenon lamp light source module for deep ultraviolet narrow bandwidth, the principle of which is shown in figure 1, the xenon lamp light source module comprises three parts, the first part is a light source module for providing emergent light; the second is a lens assembly for converging and diverging the light source spot shape, and the third is a cut-off assembly for selecting the required light source wavelength range.
In the present invention, the lens assembly includes at least one lens.
In one embodiment, the lens assembly uses 1 plano-convex lens for collimation.
Further, 2 and more than 2 lenses may be used for collimation depending on the divergence angle and spot size requirements.
Further, a diaphragm can be arranged in the lens assembly and used for changing the light spot form.
Further, the distance between the lens assembly and the light source module is adjustable. The size and the divergence angle of the emergent light spot can be adjusted by adjusting the distance between the lens and the light source.
In the present invention, the cutoff member includes a plurality of mirrors. The angles of the plurality of mirrors are adjustable to output spectra in different directions and wavelengths; the positions and directions of the plurality of reflecting mirrors can be adjusted to adapt to different space sizes and polarization state requirements of light.
As an embodiment, the cut-off component includes 4 same type mirrors, as shown in fig. 3, the reflectivity of the 4 mirrors in the required ultraviolet band is greater than 94%, the reflectivity of the band to be filtered is less than 16%, after 4 reflections, the energy of the required ultraviolet band is about 78% of the total energy, and the energy of the band to be filtered is about 0.06% of the total energy, so that the filtering effect shown in fig. 2 (T in fig. 2 represents transmittance) can be achieved, thereby replacing the conventional optical filter to realize the filtering of the required band. If a higher cut-off depth is required, the number of mirrors can be increased. If different transmittances are required, this is achieved by selecting different numbers of mirrors.
Further, a diaphragm can be arranged on an emergent light path of the cut-off component and used for changing the shape of the light spot.
Furthermore, the reflecting surface of the reflector is plated with a high-reflection film of a required wave band and an antireflection film of a wave band required to be filtered. Different light transmission ranges can be obtained by plating different films.
Further, the cut-off component is provided with an encapsulation shell, and a coating is applied to the inner surface of the encapsulation shell and used for eliminating the reflection of stray light. In addition, in order to eliminate light leakage, a baffle plate may be disposed inside the package case.
Firstly, selecting a proper light source, wherein the light-emitting waveband is stable, designing a lens assembly to have an adjusting function on the basis, changing the divergence angle and the spot size of an emergent spot by adjusting the distance between the lens and the light source, and plating the required waveband into a high reflection mode by a reflector in a cut-off assembly through the cut-off assembly, wherein the reflectivity of the waveband to be filtered is as low as possible; by the superposition effect, the band with higher reflectivity will still be higher, and the lower band mirror will be reduced to a lower effect. The invention utilizes the prior xenon lamp light source, collimates and expands the beam of the light emitted by the light source through the lens component, selects the required light source wavelength range through the cut-off component without depending on an optical filter, and realizes the requirements of ultra-narrow bandwidth and higher transmittance.
