Abstract
The utility model discloses an optical element damage threshold measuring device include: the laser instrument, the laser instrument sends laser beam, is provided with the track along laser beam's transmit direction by near to far having set gradually lens and measurement bay on the track, the measurement bay is including the pulley base, pathway movement is followed to the pulley base, is provided with perpendicular to track extending direction's scale axle above the pulley base, the epaxial sliding seat that is provided with of scale, the sliding seat removes along the scale axle, and the sliding seat top is provided with test fixture, and the optics sample wafer that awaits measuring is arranged and is installed along perpendicular and track extending direction test fixture is last. The utility model discloses an optical element damage threshold measuring device, through the damage threshold of the testable arbitrary angle sample wafer of measurement bay, but a plurality of sample wafers of simultaneous measurement still on this basis to this damage threshold who measures the sample wafer reaches the damage threshold who contrasts different sample wafers on year -on -year basis.
Description
Technical field
The utility model relates to a kind of optic element damage threshold value various measurement of comparison device.
Background technology
Along with the fast development of laser technology, laser technology is able to widespread use, required optic element damage threshold requirement is also more and more higher, and requires also more and more higher to the accuracy of measurement of optic element damage threshold value, and this wherein just needs the device for measuring damage threshold using optical element.
Measure the damage threshold of optical element, traditional method once to measure a print, and need can complete through repetitive measurement to contrast different print, which results in measuring error, what cause damage threshold to contrast is inaccurate.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of optic element damage threshold values measurement mechanism, can measure multiple print on year-on-year basis, be convenient to the contrast of different print.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of optic element damage threshold values measurement mechanism comprises: laser instrument, described laser instrument sends laser beam, transmit direction along laser beam is provided with track, extremely far lens and measurement bay is disposed with on the track by near, described measurement bay includes pulley base, described pulley base is along rail moving, the scale axle perpendicular to track bearing of trend is provided with above pulley base, described scale axle is provided with sliding seat, described sliding seat moves along scale axle, test fixture is provided with above sliding seat, treat that photometry print arranges along vertical and track bearing of trend and is arranged on described test fixture.
Further, described lens are arranged on lens mount, and described lens mount is along described rail moving.
During use, laser instrument sends laser beam, and laser beam is treated photometry print is measured through converging in after lens, and mobile sliding seat, measures multiple print successively.Test fixture is existing fixture, can measure the damage threshold of arbitrarily angled print.
A kind of optic element damage threshold values measurement mechanism of the present utility model, the damage threshold of arbitrarily angled print can be tested by measurement bay, also can measure multiple print on this basis simultaneously, measure the damage threshold of print with this, and contrast the damage threshold of different print on year-on-year basis.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of optic element damage threshold values of the utility model measurement mechanism;
Fig. 2 is the schematic diagram of measurement bay in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail.
Be the specific embodiment of a kind of optic element damage threshold values of the utility model measurement mechanism as depicted in figs. 1 and 2, specifically comprise in the present embodiment: laser instrument 1, track 2, lens 3 and measurement bay, wherein, laser instrument 1 sends parallel laser beam, transmit direction along laser beam is provided with track 2, track 2 is extremely far disposed with lens 3 and measurement bay by near, lens 3 are arranged on lens mount 8, lens mount 8 can move along track 2, measurement bay includes pulley base 4, pulley base 4 moves along track 2, the scale axle 5 perpendicular to track 2 bearing of trend is provided with above pulley base 4, scale axle 5 is provided with sliding seat 6, sliding seat 6 moves along scale axle 5, test fixture 7 is provided with above sliding seat 6, treat that photometry print 9 arranges along vertical and track 1 bearing of trend and is arranged on test fixture 7, with reference to figure 2.
During use, laser instrument 1 sends laser beam, and laser beam is treated photometry print 9 is measured through converging in after lens 3, and mobile sliding seat 6, measures multiple print 9 successively.Test fixture 7 is existing fixture, can measure the damage threshold of arbitrarily angled print 9.
A kind of optic element damage threshold values measurement mechanism of the present utility model, the damage threshold of arbitrarily angled print can be tested by measurement bay, also can measure multiple print on this basis simultaneously, measure the damage threshold of print with this, and contrast the damage threshold of different print on year-on-year basis.
Above-mentioned example is just for illustration of the utility model, and embodiment of the present utility model is not limited to these examples, and what those skilled in the art made meets the various embodiments of the utility model thought all within protection domain of the present utility model.
