BACKGROUND OF THE INVENTION
Field of the 1nvention The invention relates to the optical colour filter can be applied expediently as adapte~ for optical pickup- and projecting apparatuses, wherein layexs are arranged influencing the intensity-rate of the components of various wave lengths of the rays of light between the two light-passing barrier layers, resp. the invention relates furthermore to the method for producing such optical colour filter, on the course of which layers are arranged between the two light-passing barrier layers, influencing the intensity-rate of the components of various wave lengths of the rays of light. The proposed optical colour ~ilter adapter can equally be applied in case of using film- or video camera, respO slide projection or film projection for the continuously changeable colouration of the sight to be photographed or projected within wide limits, naturally after individual's taste.
Prior art The optical colour filters are well known in numerous executions. Its main characteristics are in that a given colour filter can be used only for producing a single later not changeable colour, which influences however the sight to be photographed respectively the picture to be projected, but there is n9 possibility for its change or its further subjective influence. Naturally it ic possible to connect more, various colour filters in series, resulting the light beam deviating from the light beam produced by the single colour filters, however, this light beam will be of determined colour dispersion. The optical colour filter adapters contain at least one light-passing layer, which ~ transmits the rays of~light-of determined-wave--length, resp.

In practice, coming the visual culture and the visual information to the front there is a greak demand for th~
fact that the person handling the pickup- or projection ap-- paratus should be able to inf~uence the sight or the picture to taste, by the aid of relative simple means, i.e.to influ-ence the incident or projected light beam ~ully or partly, more over, to change its colours. The HU-PS 188.372 specifi-cation describes a fluid crystalline optical filter, which can mainly be utllized in the photographic and television technics as objective adapter, and its form depends on its structural formation, further it can be visualized in the required period of time by the aid of electrical control,and it can be utilized for producing tick-shot of light beams, rontinuously adjustable for the requested light or stage.
The mentioned optical filter has a liquid cristalline cell placed between the two light-passing barrier layers, which serves as an influencing layer of the intensity of the component of the determined direction of the rays of light, and on the surface facing to each other o~ the the bearers forming light-passing barrier layer, are laminated to each other as bear~r, the thin film electrodP or electrodes of optically transparent, provided with outlets, insulating layer and orienting layer are applied and at least its one thin film electrode separated each other in its plane, but electrode streaks connected in galvanic way, while the liquid crystalline layer enclosed by bearers are of polarizatorless. Should one of the bearers - furthermore also light-passing - coloured in its material, so the picture to be seen will have the given shade of colour and the visualized light beam will be of the same shade of colour as well. Although by control of the electrodes the light beam observed by eyes will be of various formation, -- - striationj its colour neither in~whole nor in details can be ~ . .

modified. The HU-PS 183 . 39B specification described an optical means, particularly polar filter, which has two transparent bearers, encasing a capillary aperture and on the surface of the bearers opposite to e~ch other can be found a- positioning course system, while the capillary aperture is a material of determined order of the molec~es, ~irst of all it is filled in with liquid crystalline. The optical means produce from the incident natural light advantageously depending on the passing direction in two ways as well - polarized light beam, however, neither the nonpolarized nor the polarized light gives possibility for the individual, creative coloration.
Summary_of the_lnvention The aid o~ my invention is to realize such kind of means, by the aid of which a specified light beam within wide limits, creative and in a given case by way of artistic can be coloured so that the coloration should mean not only a single predetermined colourchange, but during the passing through of the light beam, one part or the whole of them can be coloured by continuous ad~ustable way. Furthermore the aid of the present invention is that this optical adapter could be realized simply, cheaply, without utilizing special materials and its application should need no external - energy. In addition, the aid of my invention is to utilize the so manufactured optical colour filter adapter for optical pickup and projection apparatuses expediently as adapter, e.g. it can be used as objective adapter, and their size and weight should not increase excessively.
~ y invention is based on the recognition that between the light polarizing bearer of changeable position in its plane comparing thereto, a light-passing layer with a structure of amorf large molecule is placed, this layer refracts the plane-oscillated light-passing through the fixed polar filter again to field-oscillated light. The projection of this^:-field-oscillated light-- is- directed . .

The objected task is solved by an optical colour filter adapter usable for optical pickup- and projecting apparatus-- es which comprises at least one layer batween the two light-passing barrier layers, in~luencing the intensity-rate of the components of various wave length o~ the rays of light. This optical colour filter adapter according to the invention is developed so that the layer between the barrier layers is made of large molecule foil.

The proposed method and optical colour filter adapter is mainly utilized in-the sphere of pretentious photo- and videoamateurs and its application contributes to increasing the level of visual culture. Being cheap, simple means, it renders possibility for photography as well as for projection of creative characteristic, or for realizing theatrical light-technical affects, furthermore it has a role in the colour laboratory-technics, in enlarging opera-tions as well as in the transillumination.

15In case of the mbodiments described as an advantageous example of the proposed optical colour filter adaptex three main layers can be distinguished, which are arranged behind each other in the way of the light beam. In the frame satis-fying the mechanical and strength requirements, can be-found a barrier layer 2 made of light-passing glass ~ixed for example onto a slideframe l, furthermore, a polarfilter layer 3 or layer or layers 4 influencing the intensity of the components of the determined wave-length of the light-beam, a barriex layer 5 made of light passing glass with fixed position, and outside the slideframe l a rota~able polar~ilter 6 are arrang~d as a barrier layer. It has to be noted that as the rotatable polarfilter 6 and the various means for ~ixing are well-known el~ments o~ the photography technics, the optical colour filter adapter according to the invention conn~cting with the known means, contains the barrier layer 2 made of glass, the polarfilter layer 3 resp.
-the layer or layers 4. The layer 4 comprises transparent foil of large-molecule stru~ture resulting various dehomogenized structure, which refracts the plane-oscillated polar-light coming through the polarfilter layer 3 having fixed position to field-oscillated light again.

In the present case, the slideframe 1 with the dimension S of~ 7x7 cm is used in case of framing slide's of 6x6 cm, however, utilizing different dimension from the above-mentioned one, can ensure the same result. In the slideframe 1 are arranged a glass serving as barrier layer 2 resp~
polarfilter layer 3 like foil both of them available in the trade. Then follows the layer 4 influencing the intensity of the components of the light beam, which comprises transparent ~oil of various large molecule structures. For its utili~ation, for example from cellophane such kind of formations will be cut, which covers the window of the slideframe 1 in itself, however, according to approval, it cannot cover singly the window with the dimension of 6x6 cm~
Arranging to each other more foils of such geometrical formation, will be covered the window of the slideframe, then to the so formed layer 4 is placed the glass-foil serving as barrier layer 5 and the slideframe 1 will be closed. As a result of this, in the slideframe 1 transparent layer 4 can be seen showing geometrical lines along the cutting edge, the colour of whlch will be dPveloped by the rotatable polarfilter 6. The fact is that the lines of t~e cutting edges are visible, plays role neither on the course of shooting nor of projection, as the phasing ob~ective of the apparatus is adjusted to the object to be photographed resp. in case of projection, the picture of the slide or film bands arranged in the projector window appears clearly on the screen and not that of th~ lines of the adapter placed before the objective.
As Figures 3 to 6 illustrate, the window o~ the slideframe 1 can be of whole field or various manner divided field. It can be admitted that in case, the slideframe 1 can be slipped into the holder arranged in front of the objective turning in four-kind of ways, then certain spaces --of--characterizing form,-to the picture to be~photographed or-.. . . . .. .

Differently from the above the layer 4 can be formed so - that -the foil or foils serving as layer 4 is undergone mechanical affects, for example, drawing, crumpling. This way, in the foil of the large molecule-structure, inner 0 material structure transformations come into being, i.e. the large molecule structure is dehomogenized. The surfaces of transformated structure in the course of the diffusion of the polar light behave otherwise - on the basis of my recognition - than the original intact foil. This "difference" causes discolourations of various amorphous formation in the light beam, so if to the so-formed foil a rotatable polarfilter 6 is placed, then we obtain in the slideframe 1 an optical filter with amorphous formation, which can likely be placed in four manners into the holder arranged in front of the objective of the apparatus.
Similar effect can be reached so that the foil is dehomogenized by heat-affect, ie. it will be destructed, wherein as an additional result heat identation is formed suitable for the formation of the sourcs of heat. So the visible image of the adapter can be kept in hand and can be repeatedly produced practically with the same result, contrast with the mechanical processing, which results the structural destruction by chance.
However, this feature of the lat~er is - being the object of the proposed colour filter adapter is to realize pictur s of artistic characteristics - rather to its advantage than its disadvantage.
The dehomogenized structure of the utilized foil can be realized by way of chemicals, for example by treating intensive solvent.

The modification of the wave-length or features of the utilized light for forming the foil, duriny my tests, led to applicating the laser light beam, by the aid of which the deconstruction o~ the foil can be effected by greater --accuracy and can be kept in hand.` However, utilizing ultra-violet light and by laser light beam not only an optical colour filter of changeable colour, but a slidepicture, picture-information can also be e~fected, which can be used as an artistic picture. In such a casej it is enough to use a single adapter and rotate the polar Eilter 6 and there is no needd for arranging a slide or film band containing other picture into the projector.
For dehomogenizing the layer 4, the mentioned arrange-ments can also be applicated together, but other methods resulting such kind of strurture can also be used.

The modification of the wave-length or features of the utilized light for forming the foil, duriny my tests, led to applicating the laser light beam, by the aid of which the deconstruction o~ the foil can be effected by greater --accuracy and can be kept in hand.` However, utilizing ultra-violet light and by laser light beam not only an optical colour filter of changeable colour, but a slidepicture, picture-information can also be e~fected, which can be used as an artistic picture. In such a casej it is enough to use a single adapter and rotate the polar Eilter 6 and there is no needd for arranging a slide or film band containing other picture into the projector.
For dehomogenizing the layer 4, the mentioned arrange-ments can also be applicated together, but other methods resulting such kind of strurture can also be used.
