Description
Technical field
The utility model belongs to photosensitive material determination techniques field, is specifically related to a kind of sample containment device measured for liquid photosensitive material spectrum.
Background technology
Photosensitive material is that one can experience the concurrent raw physical and chemical changes of electromagnetic radiation information such as visible ray, infrared light, ultraviolet, X ray, after overexposure and certain processing, the article of image can be fixed, photosensitive material is as the important medium of information record and display, relate to culture, education, medical treatment, science, national defence the field such as photography and vedio recording, plate making, photo-curing material played great function, in national economy, there is consequence at station.Photosensitive material can run into the radiation of spectrum different wave length, and has obvious selectivity to it.The spectrum sensitivity of photosensitive material is then in order to represent its radiation sensitive effect to different wave length.Same photosensitive material can obtain different photosensitive effects under the radiation effects of different wave length, and different photosensitive materials is under the radiation effects of Same Wavelength, also can obtain different photosensitive effects.Thus, for photosensitive material factory and user, setting up the assay method of spectrum sensitivity, is very necessary to evaluating photosensitive material quality all sidedly.People, by the mensuration to photosensitive material spectrum sensitivity, can select best photosensitive condition exactly, improve light receiving efficiency, also can be and select the safety lighting condition of photosensitive material to provide reliable foundation.
Photosensitive material comprises silver sensitive material and non-silver salt photosensitive material, usually photosensitive material dissolution, in water or in solvent, is then coated on base material, obtains solid cladding after drying.Its photo-process betides solid state.For solid cladding photosensitive materials such as this photosensitive dry plate, film, galleys, ripe equipment and method has been had to measure the spectrum sensitivity of photosensitive material, photoactive spectrum instrument is also design according to this type of solid cladding, is applicable to the mensuration measuring the chip solid light sensitive layers such as film film, dry plate; The assay method of standard GB/T/T10557-1989: light source, through beam splitting system, forms the spectrum be made up of monochromatic light, is changed by photomodulator and arrives the spectral power in spectrum face, makes material to be tested obtain the exposure of different-energy under one group of full spectral conditions.
Because photoactive spectrum instrument needs longer light splitting optical path, limit apparatus structure, when this device measures spectrum sensitivity, light sensitive layer can only with upright state be attached to take the photograph spectrum window carry out spectroscopic assay, and require that photographic layer is even, smooth, be therefore only applicable to the mensuration of solid light sensitive layer, liquid photosensitive material is due to mobility, cannot erect, more be difficult to obtain even, smooth photographic layer.。
In recent years, the liquid photosensitive material, particularly photo-curing material of not moisture or solvent, as UV ink, gloss oil etc., application is original more extensive.It utilizes UV initiation to have chemically active liquid material rapid polymerization and is cross-linked, instantaneous solidification film forming.It is thinning agent with activated monomer, is in liquid condition time photosensitive, solidification or crosslinked completely after reaction, equal no liquid volatile dry process before and after reaction.Because low viscous liquid very easily trickles, liquid photosensitive material cannot be erect, and is more difficult to obtain even, smooth photographic layer.Liquid photosensitive material cannot measure photoactive spectrum according to the method for solid light sensitive layer material.
Use ultraviolet visible spectrometry to measure the absorption curve of liquid photosensitive material, the receptivity of photosensitive material to different wave length energy can be judged.But photoresponse complicated mechanism, material absorption spectrum energy differs and surely photoresponse occurs, or has different transformation efficiencies; In addition, energy trasfer can occur after material absorbing wavelength, the photosensitizer beyond optical source wavelength also can cause photosensitization.The absorption spectrum of photosensitive material can not be completely corresponding with photoactive spectrum, and ultraviolet visible spectrometry can only measure the absorption curve of liquid photosensitive material, due to energy conversion efficiency and energy transferring, transfer, cannot obtain real photoactive spectrum.
Therefore, liquid photosensitive material photoactive spectrum can only be measured by the method for liquid film; For full-bodied liquid photosensitive material, in order to avoid spectrum window taken the photograph by surface contamination photoactive spectrum instrument, can at coating surface covered with protective film; And for general liquid photosensitive material, liquid film surface coverage diaphragm, can not obtain even, that thickness is controlled coating, film is erect, the rear liquid of extruding drops down stream, cannot measure photoactive spectrum.
