Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an array-type optical beam splitting system. Background Technology

[0002] Currently, biochemical analyzer spectrophotometers typically use dichroic filters, interference filters, or grating monochromators to achieve spectrophotometric effects. Among these, spectrophotometers using dichroic filters or interference filters generally employ a linear array for multi-wavelength spectrophotometry. This structure results in a long optical path, with increasing light loss as the wavelength increases, placing high demands on hardware compatibility. Furthermore, this structure occupies a significant amount of linear space, which is detrimental to instrument layout. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an array-type optical beam splitting system that is easy to use and highly stable.

[0004] The technical solution of this utility model is as follows: it includes a package, a light source disposed within the package, and a beam splitting module corresponding to the light source. The beam splitting module includes a beam splitter, a reflecting unit, and a receiving unit. An optical channel is disposed along the axial direction corresponding to the light source within the beam splitter. The reflecting unit includes a plurality of first reflective sheets linearly disposed within the optical channel and a second reflective sheet correspondingly disposed within the reflection channel of the first reflective sheets. An angle is provided between adjacent groups of first reflective sheets. The receiving unit is correspondingly disposed on the output end of the second reflective sheet. The receiving unit includes a filter and a light receiver disposed behind the filter. After the light from the light source is reflected multiple times by the reflecting unit, the light receiver obtains the light change information of the multi-wavelength channels of the light source.

[0005] As can be seen from the above scheme, the encapsulation body is used to form a closed optical path system, which is not affected by external interference. The first reflector is used to perform semi-transparent reflection of the light emitted from the light source, and the second reflector is used to perform semi-transparent reflection of the light reflected from the first reflector. The first and second reflectors are used to reflect the light signal of their corresponding channel, while the light signals of other channels are transmitted. The filter is used for filtering. After the filter obtains the required high-purity wavelength light wave, it is then combined with the light receiver of each channel to obtain the light change information of the multi-wavelength channels of the unique light source. This utility model separates and identifies light waves through the beam splitting module. This utility model reduces the optical path length of each wavelength channel in a multi-wavelength beam splitting system with more than 10 channels, reducing light loss. It effectively reduces the structural volume of the entire multi-channel beam splitting system, greatly improving the layout convenience of the overall instrument; it effectively reduces the hardware adaptation requirements of each wavelength channel, simplifies the supporting hardware configuration requirements, and the optical path system is fully enclosed, unaffected by external environmental conditions. This utility model integrates the beam splitting module with the light source, making installation convenient and eliminating the need for optical path adjustment.

[0006] The package includes a first mounting base and a second mounting base connected to the first mounting base. The first mounting base has a first mounting through hole corresponding to the light source, and the light channel is coaxially arranged with the first mounting through hole. Therefore, the light source emits light from the first mounting through hole into the light channel within the second mounting base.

[0007] The light source includes a single light-emitting element disposed on the first mounting base, and a collimator is disposed on the first mounting base corresponding to the first mounting through hole. Thus, the single light-emitting element is used to realize the emission of light from a single light source, facilitating the subsequent obtaining of multi-wavelength channel light change information of the unique light source after beam splitting. The collimator is used to convert external light signals into collimated light before entering the beam splitting module, thereby performing optical path shaping.

[0008] The second mounting base is provided with a control board, and the beam splitter is connected to the control board.

[0009] The second mounting base has light reflection channels on both sides of the light channel, and the second reflective sheet is disposed within the light reflection channel. Any group of the second reflective sheet corresponds to two groups of light receiving units. Therefore, the light reflection channel is used to reflect and filter light passing through several first reflective sheets one by one.

[0010] The angle between any two adjacent sets of the first reflective sheet is a right angle.

[0011] The first and second reflective sheets are semi-transparent reflective sheets. Therefore, it can be seen that the first and second reflective sheets... Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1 to 3 As shown, this utility model is an array-type optical beam splitting system, including a package 1, a light source 2 disposed within the package 1, and a beam splitting module corresponding to the light source 2. The beam splitting module includes a beam splitter 3, a reflecting unit, and a receiving unit. An optical channel 31 is arranged axially within the beam splitter 3 corresponding to the light source 2. The reflecting unit includes a plurality of first reflecting sheets 4 linearly disposed within the optical channel 31 and second reflecting sheets 5 correspondingly disposed within the reflecting channels of the first reflecting sheets 4. An angle is provided between adjacent groups of first reflecting sheets 4. The receiving unit is correspondingly disposed on the output end of the second reflecting sheet 5. The receiving unit includes a filter 6 and a light receiver 7 disposed behind the filter 6. After the light passing through the light source 2 is reflected multiple times by the reflecting unit, the light receiver 7 obtains the light change information of the multi-wavelength channels of the light source 2.

[0017] In this embodiment, several first reflective sheets 4 have different wavelengths, and several second reflective sheets 5 have different wavelengths. The system arranges multiple multi-wavelength first reflective sheets 4 in opposite directions along the axis of the light source 2, and then arranges suitable second reflective sheets 5 in each optical path channel to form a multi-row optical path array. Each row and column is then equipped with a filter 6 of a suitable wavelength to obtain the required high-purity wavelength light wave. Combined with the light receiver 7 of each channel on the control board, the light change information of the multi-wavelength channels of the unique light source can be obtained.

[0018] The package 1 includes a first mounting base 11 and a second mounting base 12 connected to the first mounting base 11. The first mounting base 11 is provided with a first mounting through hole 13 corresponding to the light source 2. The light channel 31 is coaxially arranged with the first mounting through hole 13.

[0019] The light source 2 includes a single light-emitting element disposed on the first mounting base 11, and the first mounting base 11 is provided with a collimator 14 corresponding to the first mounting through hole 13.

[0020] A control board 15 is provided on the second mounting base 12, and the beam splitter 3 is connected to the control board 15. Light reflection channels 32 are provided on both sides of the light channel 31 inside the second mounting base 12, and the second reflective sheet 5 is disposed in the light reflection channel 32. Any group of the second reflective sheet 5 corresponds to two groups of light receiving units.

[0021] The included angle between any two adjacent sets of the first reflective sheet 4 is a right angle.

[0022] The first reflective sheet 4 and the second reflective sheet 5 are semi-transparent reflective sheets.

[0023] The working process of this invention is as follows: the light source 2 enters the light channel 31 through the collimator 14. The shaped light path passes sequentially through several first reflective sheets 4 in the light channel 31 and then enters the light reflection channel 32, where it undergoes semi-transparent reflection through the second reflective sheet 5. The filter 6 in the light reflection channel 32 filters the light, which is then received by the light receiver 7. The light change information of the multi-wavelength channel of the single light source is obtained through the reflection of the arrayed reflective units. This invention reduces light loss through the reasonable layout of the reflective units, effectively reduces the structural volume of the entire multi-channel beam splitting system, and greatly improves the layout convenience of the overall instrument.

[0024] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
