| Abstract: | This paper introduces a new method for measuring concave lens focal length taking a laser light as source. This method, without any supporting apparatus, in accordance with the FPA and Viceaxis mapping feature can read directly the concave lens focal length. Experiments show that this method bears the qualities of having simple operating way, producing more accurate results, and the relative error is only 0. 79%. |
