Description
[technical field]
Patent of the present invention relates to a kind of compensator in the optical element, especially a kind of broadband achromatism Suo Lier-Babinet compensator.
[technical background]
Can make two field vectors that vibrate on mutually perpendicular direction produce the certain optical path difference or the device of phase differential, be called compensator, it is the phase differential of may command that compensator can continuously change the orthogonal two bunch polarized lights generation of direction of vibration.Traditional compensator has Babinet compensator and Suo Lier-Babinet phase compensator: Babinet compensator is split by the quartz crystal of two homogeneities and is formed, these two optical axises of splitting are vertical mutually, its shortcoming is to use superfine incident beam, because the different piece of wide light beam can produce different phase differential; And Suo Lier-Babinet phase compensator can remedy this deficiency, it is made up of two parallel quartz wedges and a quartzy surface plate, the optical axis that the optical axis of quartz plate and two is split is vertical, on split and can make it parallel by fine adjustment screw and move, thereby change light obtains certain wavelength by two gross thickness of splitting phase value.
Compensator can produce needed wave plate on any wavelength; Can compensate and offset the natural birefringence of an element; Also can in an optical device, introduce a fixing delay biasing; After the calibration calibration, can also be used to measuring the phase delay of waiting to ask wave plate.Therefore in a lot of optical instruments, value has a wide range of applications.
But in laser system, optical communication device and optical tests measurement instrument, the polarized systems of consumption such as digital camera industry needs to use simultaneously a plurality of wavelength in the polarization light path.Babinet compensator and Suo Lier-Babinet phase compensator can only once be used a wavelength, and this not only makes the polarization light path become complicated, and the present invention combines above application demand, has invented broadband achromatism Suo Lier-Babinet phase compensator.
[summary of the invention]
The present invention is on the basis of Suo Lier-Babinet compensator, adopt different crystalline materials, it is adjustable to have increased the broad band wavelength colour killing, be referred to as broadband achromatism Suo Lier-Babinet phase compensator, its effect is similar to the adjustable zero-th order waveplates of phase-delay quantity in a broadband, and adjustable extent is at 300-2500nm, and wavelength bandwidth surpasses 200nm even wideer, retardation 0-360 °, postpone precision up to λ/500.
Technical scheme of the present invention is as follows: a kind of broadband achromatism Suo Lier-Babinet compensator, form by the birefringece crystal material of four angles of wedge, and it is characterized in that: the optical axis of crystalline material of the same race is parallel; The optical axis of crystalline material of the same race is not orthogonal.Described crystalline material can be quartz crystal, magnesium fluoride crystal, icelandspar crystal.The described crystal angle of wedge can move left and right.The wavelength regulation scope is at 300-2500nm.The retardation range of adjustment is at 0-360 °.The retardation of compensator can be at the wave band achromatism that surpasses more than the 200nm.Described crystalline material can optical cement, gummed or air-gap connect.
