| Abstract: | In this paper is proposed a new method for measuring the focal length of con-cave lens in which the determination of the clarity of the image formation is convertedinto determination of the depth of parallelism of refractive light, so as to eliminate theerrors induced by subjective factors as is often the case in measurement methods in com-mon use. |
