Meopta Colour 3 Head
enables a continuous, smooth setting of the density required for the given correction filter. Any of the three filters is set by means of turning knobs Y, M and C on the front panel of the instrument, fitted with illuminated scales. The interference filters used, which have been manufactured by vacuum-evaporation of dielectric layers on a glass carrier, are highly heat resistant, color - fast and their service life is practically unlimited. The filtration range of all three filters is 0...200 filtration units. The set color filtration can be easily cleared by the controlling device on the left side of the instrument. Moreover the head for color photography is fitted with an adjustable density stop. Setting of the exit luminous flux is accomplished by means of a perforated stop which is introduced into the light path by means of the turning knob D. The maximum scale value is 60 density units which corresponds approximately to 2 stop numbers of the lens. The set density stop can be put out of function by means of the controlling device situated on the right side of the instrument.
