    摘要: Absorbent film which has a great adhesion, a great mechanical strength and a high resistivity to heat and other radiation and which is applicable to sun glasses, color filters, phase plates used for the differential phase method, apodization filters and the like. The absorbent film is produced by mixing together powdered Ti, powdered Cr and powdered MgF.sub.2 into the form of a powdered mixture or shaping them into a compressed mass of mixture, thereafter vacuum-evaporating said mixture onto a predetermined base material such as lens glass to thereby provide a refractive factor of about 1.52 and an absorption coefficient of about 0.01 to 0.4. At least one layer of such absorbent film may be used to form a multi-layer film structure.
