Conic Constant

PowerPhotonic Lens Calculators

The conic constant describes the curve obtained as a conic surface intersects with a plane. There are three general types of conic section: Hyperbola, Parabola and Ellipse (a Circle is a special Ellipse).

Please enter the appropriate constant as shown in the image.
