Abstract
The utility model relates to a laser power wet-type measurement adapter. The optical fiber measuring device mainly comprises a liquid tank cavity for containing liquid, wherein one end of the liquid tank wall on the outer wall of the liquid tank cavity is provided with a connecting flange and is connected with a dry-type measuring laser power meter, the upper end of the liquid tank wall is provided with an opening for inserting an optical fiber tool bit to be measured in the liquid tank cavity, an anti-reflection window is arranged between the liquid tank wall and the connecting flange, and the other end of the liquid tank wall, opposite to the anti-reflection window, is provided with an observation window. The adapter is used by being matched with an original dry-type measurement laser power meter, has a simple structure, enlarges the application range of the original laser power meter, and solves the practical application problem of wet-type power measurement.
Description
The utility model relates to the wet type of laser power measurement and measures adapter.
Prior art, the product of the existing multiple model of the power meter of Laser Measurement power, as LM-1, the LM-92II of china institute of metrology, the laser powermeter of CLM-200 type, Beijing photoelectricity JC-1 of research institute laser power monitor device and Shanghai Testing Technology Study SJG-100A type laser powermeter etc.Above-mentioned each laser powermeter all adapts to the power of measuring the laser beam of transmitting in the air, is called dry type and measures.In the various medical light-conductive optic fibre system of development in recent years, some is led in the human body by endoscope system, and laser beam is treated lesions position in liquid (physiological saline, glucose, aquae destillata etc.) environment.This optical tool bit emitting laser, the quantitative measurment of irradiation diseased region watt level, it is the important parameter that carries out laser medicine pathological study and preferred optimum therapeuticing effect, the power meter that only has at present the dry type measurement can not be finished the demand that this wet type is measured, and for some side emission type optical tool bit, when dry type is measured power,, often cause the overheated of emergent light end and self-destruction because of not cooling off.
The purpose of this utility model is a weak point of measuring power meter at above-mentioned dry type, proposes a kind of on the basis of dry type Laser Measurement power meter, can be to the liquid environment power of the laser fiber cutter head of work down, the adapter that directly carry out the wet type measurement.
This wet type is measured adapter, mainly comprises: connecting flange 1, an end of connecting flange 1 are that the probe 7 of measuring light activated element 8 front ends of power meter with dry type links, and the interface shape of its flange 1 and caliber size all are complementary with the concrete laser powermeter of model.The other end of connecting flange 1 is connected with liquid pool wall 2, and the cavity in the liquid pool wall 2 is called liquid pool chamber 10, is contain fluid.There is opening 9 upper end of liquid pool wall 2, and opening 9 is to be the usefulness in the liquid in the testing fiber cutter head insertion liquid pool chamber.There is small opening 6 side, liquid pool wall 2 bottom, for discharge liquid is used.Between liquid pool wall 2 and the connecting flange 1 enhanced window 3 is housed, corresponding with enhanced window 3, at liquid pool wall 2 other ends watch window 4 is housed, there is extinction cover 5 in the outside of watch window 4.As shown in Figure 1.
Said liquid pool wall 2 is to be made by corrosion-resistant material.The optical glass material of enhanced window 3, reply treats that the optical maser wavelength of power scale is transparent, and is two-sided optical maser wavelength to be measured to be coated with anti-reflection film, to reach the printing opacity loss that reduces window to greatest extent.The optical glass material of watch window 4 is tackled the visible waveband optical transparency, is convenient to replace with the coaxial pilot light of visible waveband when measuring the laser beam of invisible wave band to be measured, observes adjustment, and aims at power meter light activated element 8.The extinction cover 5 of black rough surface is after alignment, covers watch window 4, absorbs the faint reflected light from light activated element 8 and 3 pairs of laser beam of enhanced window, and operating personnel are played the security protection effect.
This wet type is measured adapter, and adopt said structure that following advantage is arranged: member is simple; Measure the power meter adapted with existing dry type and can realize the wet type measurement, expanded the function of original power meter; It is minimum that the additive error that enhanced window 3 is measured wet type reduces to; Watch window 4 is convenient to range estimation to light, covers extinction cover 5 backs and guarantees survey crew safety.
Description of drawings:
Fig. 1 is the structural representation that the laser power wet type is measured adapter.
Embodiment:
The laser power wet type of the SJG-100A type laser powermeter adapted of being produced with reference to the adapter and the Shanghai Testing Technology Study of Fig. 1 structure is measured adapter, the connecting flange 1 of adapter replaces former laser powermeter light is covered, opened round hole in the middle of the flange 1, liquid pool wall 2 is picked out outside the lid, flange 1 still uses M48 * 1.0 screw threads to link to each other with the SJG-100A probe, and it is fastened on the integral body of adapter on the probe.Column liquid pool wall 2 is made of plastic, and liquid is had corrosion resistance, column length 40mm, and internal diameter φ 28mm, but when wherein the liquid capacity submergence was treated the optical tool bit of power scale and guaranteed the YAG laser beam of cutter head output 100W, the cooling cutter head had enough liquid consumptions.Enhanced window 3 adopts the K of φ 20 * 1
9The optical plate glass eyeglass two-sidedly plates anti-reflection deielectric-coating to 1.06 mum wavelengths; The K of watch window 4 usefulness φ 30
9Planar optics glass mirror, eyeglass and liquid pool wall seal.Extinction cover 5 inboards are coated with berlin black seven.
Present embodiment, be successfully used to medical YAG Lasar prostate therapeutic equipment the measurement of the laser power in liquid environment, exported of special-purpose side emission type silica fibre cutter head, solved the problem that original side emission type cutter head output laser power value can't be surveyed.
