Description
[technical field]
The utility model belongs to technical field of laser processing, is divided more particularly to a kind of adjustable laser energy of splitting ratio
Device.
[background technique]
Traditional laser light splitter generally uses beam splitter, and perhaps beam splitter prism perhaps self-focus lens or is directly adopted
Light splitting is realized with the mode that physics is truncated.The splitting ratio of common beam splitter is 10T:90R, 30T:70R, 50T currently on the market:
50R, non-standard splitting ratio spectroscope cost especially at a particular wavelength is very expensive, and customizes that the period is longer, finished product
Rate is low.A kind of equipment that can dynamically change splitting ratio is also needed in certain occasions, this is nothing for traditional beamsplitter element
What method was realized.
Therefore, it is necessary to provide the new adjustable laser energy optical splitter of splitting ratio of one kind to solve the above problems.
[utility model content]
The main purpose of the utility model is to provide a kind of adjustable laser energy optical splitters of splitting ratio, realize laser
Energy can be divided according to any splitting ratio, and low manufacture cost.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of adjustable laser energy light splitting of splitting ratio
Device comprising the first half-wave plate, quartz glass plate and the second half-wave plate, the quartz glass plate is arranged in 45° angle degree, described
First half-wave plate and second half-wave plate are separately positioned on the two sides of the quartz glass plate, first half-wave plate, described
The optical axial of quartz glass plate and second half-wave plate is collinearly arranged.
Further, the uncoated quartz glass plate that the quartz glass plate is common pair.
Further, the positioning mark for being convenient for positioning when adjusting is provided on first half-wave plate and second half-wave plate
Note.
Further, the telltale mark includes notch, mark point or mark protrusion.
Compared with prior art, a kind of beneficial effect of the adjustable laser energy optical splitter of splitting ratio of the utility model exists
In: it by the setting of two half-wave plates, realizes and energy light splitting is only carried out to target beam, do not change its any feature；Pass through
The design of half-wave plate, which is realized, is divided target beam arbitrary proportion, convenient for being flexibly adapted to various optical path demands；Pass through two and half
Wave plate realizes light splitting, greatly reduces purchase cost and cost of manufacture.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Digital representation in figure:
The adjustable laser energy optical splitter of 100 splitting ratios；1 first half-wave plate；2 quartz glass plates；3 second half-wave plates.
[specific embodiment]
Embodiment:
Fig. 1 is please referred to, the present embodiment is the adjustable laser energy optical splitter 100 of splitting ratio comprising the first half-wave plate 1,
Quartz glass plate 2 and the second half-wave plate 3, quartz glass plate 2 are arranged in 45° angle degree, the first half-wave plate 1 and the second half-wave plate 3
It is separately positioned on the two sides of quartz glass plate 2, the optics of 3 three of the first half-wave plate 1, quartz glass plate 2 and the second half-wave plate
Axis collinear setting.
The quartz glass plate for the non-plated film pair that quartz glass plate 2 is common pair in the present embodiment.
First half-wave plate 1 is mainly used for for linearly polarized light being adjusted to circularly polarized light, the second half-wave plate 3 then by circularly polarized light again
Adjust loop line polarised light.
The telltale mark convenient for positioning when adjusting, the telltale mark are provided on first half-wave plate 1 and the second half-wave plate 3
Including notch, mark point or mark protrusion.
By the first half-wave plate 1 of rotation and the second half-wave plate 3, make the polarization direction of the first half-wave plate 1 and the second half-wave plate 3
It is identical；The polarization direction of ultraviolet light beam is horizontal direction, and ultraviolet light beam can resolve into it two parts, a part of light vector
In the plane of incidence, i.e. parallel component；The light vector of another part is perpendicular to the plane of incidence, i.e. vertical component.Due to parallel component and
The reflection coefficient of vertical component is different, thus energy of the ultraviolet light beam by the reflected beams and deflecting light beams when quartz glass plate 2
Ratio is also different.Energy proportion is related with the polarization direction of incident light.When the polarised light incidence of horizontal direction, system
Transflection is than being about 80T:20R.First half-wave plate 1 can rotate polarised light.Because linearly polarized light impinges perpendicularly on first
Half-wave plate 1, transmitted light are still linearly polarized light, if angle when incident between 2 main cross section of vibration plane and quartz glass plate is θ,
The vibration plane of the linearly polarized light then transmitted turns over 2 angles θ from original orientation.Between target beam and quartz glass plate 2
For the first half-wave plate 1 being arranged for changing the polarization direction of incident beam, the transflection that laser beam can be realized in this way compares range
For 99T:1R to 80T:20R variation, this numberical range and the substrate material that we use are related to the transflection ratio of incident light.
The beneficial effect of the adjustable laser energy optical splitter 100 of the present embodiment splitting ratio is: passing through two half-wave plates
Setting, realizes and only carries out energy light splitting to target beam, do not change its any feature；It is realized by the design of half-wave plate to mesh
The light splitting of light beam arbitrary proportion is marked, convenient for being flexibly adapted to various optical path demands；Light splitting is realized by two half-wave plates, is substantially reduced
Purchase cost and cost of manufacture.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
