A free, simple, and easy to use calculator to analyze the conoid of Sturm which is formed by any chosen spherocylinder lens.
Features:
* Calculate locations of the principal focal lines of the lens.
* Calculate the focal interval of Sturm.
* Calculate location of the 'circle of least confusion'.
* Determine the focal location across any meridian of the lens.
* Calculate these values for both object at infinity (parallel light rays) and object at any selected distance.
