Description

Measure the device of glass ultraviolet ray filtering through the sunshine ultraviolet spectrum

Technical field

The utility model relates to glass ultraviolet ray filtering field of measuring technique, particularly relates to a kind of device of measuring the glass ultraviolet ray filtering through the sunshine ultraviolet spectrum.

Background technology

According to GB/T 18830-2009, daylight ultraviolet radiation (being called for short " UVR ") is meant that wavelength is the electromagnetic radiation of 280nm～400nm.Wherein daylight ultraviolet ray (being called for short " UVA ") is meant the daylight ultraviolet radiation of wavelength in 315nm～400nm scope; Daylight ultraviolet ray (being called for short " UVB ") is meant the daylight ultraviolet radiation of wavelength in 280nm～315nm scope.

Solar ultraviolet radiation is the solar radiation of 100nm～400nm wave band, and because of the absorption of atmospheric envelope ozone, the UV radiation that can arrive ground is the part of solar ultraviolet radiation, only comprises UVA and UVB.Big quantity research shows that excessive UV radiation is extremely harmful to terrestrial ecosystem and human health, and wherein UVB is maximum to human harm, can bring out solar dermatitis, and excessive exposure can make the skin canceration probability increase; UVA can make skin tanning and cause freckle.

Consult patent disclosed, that relate to " ultraviolet " and " glass ", be mostly the application and development of ultraviolet ray intercepting glass.CN01229715.1 relates to a kind of ultraviolet ray intercepting glass, is provided with layer of transparent coating between the two-layer clear glass, and this utility model is simple in structure; Processing and fabricating is convenient, and is easy to clean, long service life; Antiultraviolet system can reach 99.9%, is a kind of ideal product of antiultraviolet.CN200920279021.6 relates to villa, high-grade dwelling house antiultraviolet, the anti-riot glass of noise reduction sound; Comprise internal layer and glass outer body; Be pasted with safety diaphragm in the Vitrea inboard of skin, when double glazing receives external impact, can be along glass surface with stressed diffusion; Reduce the impulsive force that the glass surface each point receives significantly, keep that glass is complete not to break.Do not see the open content that detects for the glass ultraviolet ray filtering; Simultaneously, sunshine is as the ultraviolet source that can obtain easily on the ground, and is with low cost, safety.

Summary of the invention

The utility model technical matters to be solved provides a kind of device through sunshine ultraviolet spectrum measurement glass ultraviolet ray filtering, can measure the ability of glass ultraviolet ray filtering accurately and efficiently.

The utility model solves the technical scheme that its technical matters adopted: a kind of device of measuring the glass ultraviolet ray filtering through the sunshine ultraviolet spectrum is provided; Comprise fibre-optical probe, spectrometer and computing machine; Described fibre-optical probe is gathered input end through optical fiber and spectrometer and is linked to each other, and the output terminal of said spectrometer links to each other with computing machine; Said fibre-optical probe is arranged on a side of glass to be measured, and described glass opposite side to be measured is a sunshine.

Described optical fiber is multimode optical fiber.

Beneficial effect

Owing to adopted above-mentioned technical scheme, the utility model compared with prior art has following advantage and good effect: (1) is with low cost: the sun is as the ultraviolet source that can obtain easily on the ground; (2) rapidly and efficiently: the shooting of ultraviolet spectrum only needs get final product several seconds; (3) accuracy is high: because ultraviolet band belongs to the non-visible light wave band, the embarrassment that the ultraviolet spectrum testing result has avoided artificial sense to estimate; (4) applicability is strong: it is simple to operate that this installs required ultraviolet spectrometer (UVS), and this device can be applied.

Fig. 2 is the sunshine ultraviolet spectrum, and wherein spectral line 7 corresponding no glass block; Spectral line 8 correspondences have glass to be measured to block;

Fig. 3 is a solar ultraviolet transmitance spectrogram.

Embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

The embodiment of the utility model relates to a kind of device of measuring the glass ultraviolet ray filtering through the sunshine ultraviolet spectrum; As shown in Figure 1; Comprise fibre-optical probe 3, spectrometer 5 and computing machine 6; Described fibre-optical probe 3 links to each other with the collection input end of spectrometer 5 through optical fiber 4, and the output terminal of said spectrometer 5 links to each other with computing machine 6; Said fibre-optical probe 3 is arranged on a side of glass 2 to be measured, and described glass 2 opposite sides to be measured are sunshine 1.Wherein, optical fiber 4 can be selected multimode optical fiber for use, thereby reduces cost.

As shown in Figure 1; Light signal is gathered input end through optical fiber 4 with the light of spectrometer 5 and is connected, and the output terminal of spectrometer 5 is connected with computing machine 6, and the scanning wavelength scope is set in 280nm～400nm; Carry out data collection and analysis, the sunshine ultraviolet spectrum shows at computer screen.The UV radiation intensity of spectral line was carried out ratio when the UV radiation intensity of spectral line hid with no glass to be measured in the time of will having glass to be measured to hide; Obtain the ultraviolet ray transmissivity of respective wavelength; Set up corresponding ultraviolet ray transmissivity spectrogram; And, judge that glass to be measured filters the ability of solar ultraviolet according to solar ultraviolet spectrum and ultraviolet permeability spectrogram.

As shown in Figure 2, do not place glass 2 to be measured, obtain " nothing is blocked " spectral line 7; Glass 2 to be measured is hidden fibre-optical probe 3 fully, " glass is arranged " spectral line 8 that obtains.The data analysis system that uses a computer, the UV radiation intensity of the spectral line 8 that will " glass be arranged " is carried out ratio with the UV radiation intensity of " nothing is blocked " spectral line 7, obtains the ultraviolet ray transmissivity of respective wavelength, sets up corresponding ultraviolet permeability spectrogram, referring to shown in Figure 3.Judge that according to Fig. 2 and Fig. 3 the glass to be measured 2 in this practical implementation has filtered the ultraviolet (UV) B of 300nm～315nm wave band in the sunshine well, filtered sunshine middle-ultraviolet lamp UVA preferably simultaneously, particularly at 320nm～360nm wave band.
