Abstract

Densitometrul, conform inventiei, este format dintr-un dispozitiv optic în care se gaseste sursa de lumina, suportul pentru filtrele standard si traductorul fotoelectric, un bloc de aliniere care realizeaza amplificarea preliminara, diferentiata, a semnalelor electrice furnizate de traductorul fotoelectric si o schema de fixare a limitei inferioare a domeniului de masura formata dintr-o sursa de tensiune reglabila si un amplificator diferential. Aparatul, conform inventiei poate masura densitatea optica a imprimatelor alb-negru si color pe suporturi opace aflate în stare uscata si umeda putînd fi utilizat în atelierele de fotoreproducere, pregatirea formei si sectiile de productie din industria poligrafica precum si în laboratoarele foto profesionale, cinematografice, industria chimica s.a.
