Abstract
DENSITOMETRO FOTOGRAFICO. COMPRENDE UNA LENTE CONDENSADORA (14), SITUADA FRENTE A UNA ABERTURA (7), QUE CONVERGE LA LUZ RADIADA POR UNA LAMPARA O FUENTE LUMINOSA (4). UN CONVERTIDOR FOTOELECTRICO (16) SE COLOCA EN CONTACTO CON EL MATERIAL (5) A MEDIR,QUE A SU VEZ SE SITUA SOBRE LA ABERTURA (7). ENTRE LA FUENTE LUMINOSA (4) Y DICHA ABERTURA (7) SE DISPONE UN FILTRO DE COLOR (12). DE APLICACION A LA MEDIDAD DE LA DENSIDAD DE COLOR DE UNA FOTOGRAFICA Y DE LA DENSIDAD DE REFLEXION DE TINTA DE UNA OBJETO IMPRESO.
