Paper Abstract

Inverted focometer is a transformation of the traditional focomete, and optical lens focal length is an important technical indicators of optical system.The inverted focometer was used to measure the optical lens focal length, an expression between the ruling span of poroo-plate glass and the focal length of measured optical system was deduced according to inverted focometer design, the S-F figure graphic representation was developed , the S-F graph which could express relation of data was obtained, and steps of designing poroo-plate glass were analyzed .The S-F figure graphic representation is simple, intuitive and easy to design.
