Description
Stosujac w lampach oswietlajacych ciemnie fotograficzne filtry swietlne, przepuszczajace mieszanine promieni czerwonych o dlugosci fali o wiekszej od 6500 A i zielonych o dlugosci fali o 5100 — 5300 A otrzymuje sie swiatlo zblizone barwa i dzialaniem na zmysl wzroku do bialego.Masowa produkcja filtrów, przepuszczaja¬ cych promienie o takim skladzie widmowym, napotyka jednakze na trudnosci z uwagi na ko¬ niecznosc rozbicia warstwy filtrujacej na drob¬ na mozaike, skladajaca sie z filterków czerwo¬ nych i zielonych, gdyz tworzenie warstwy jed¬ norodnej, przepuszczajacej wymienione promie¬ niowanie, jest trudne z braku wlasciwych barw¬ ników.Niedogodnosci powyzsze mozna usunac przez stworzenie filtru przepuszczajacego promienie o zielone o dlugosci fali 5300 — 5850 A i czerwo- o ne o dlugosci fali wiekszej od 6500 A.Zasadniczy charakter oswietlenia i jego za¬ lety nie ulegaja wskutek tego wydatnym zmianom.Praktycznie biorac warstewka filtrujaca sklada sie z przezroczystej substancji, np, zela-4 tyny lub celulozy, zabarwionej mieszanina barwników organicznych. W przypadku mozai-^ ki filtrów moga to byc drobne figurki geome¬ tryczne o barwach czerwonej i zielonej wyko¬ nane z odpowiedniej substancji zabarwionej i naniesionej dowolnym sposobem, np. fotoche¬ micznym lub drukarskim, na odpowiedni pod¬ klad, np. szklo, celuloid, papier lub tkanine. PLBy using photographic light filters in lamps illuminating dark photographic light filters, transmitting a mixture of red rays with a wavelength greater than 6500 A and green rays with a wavelength of 5100 - 5300 A, light is obtained with a similar color and action on the sense of sight to white. Mass production of filters, passes through. However, it is difficult to break the filter layer into a fine mosaic consisting of red and green filters, because the formation of a homogeneous layer, transmitting the above-mentioned radiation, is difficult. difficult due to the lack of proper dyes. The above inconvenience can be overcome by creating a filter that transmits green rays with a wavelength of 5300 - 5850 A and red rays with a wavelength greater than 6500 A. The basic nature of the lighting and its advantages are not affected by practically the filter film consists of a transparent substance, e.g. gelatin or cellulose, a colored mixture of organic dyes. In the case of a filter mosaic, these may be small geometric figures of red and green colors, made of a suitable colored substance and applied by any means, for example photochemical or printing, to a suitable base, for example glass, celluloid, paper or fabric.
