Gain a deeper understanding of why diameter effects thickness, why different base curves are better than others, and much more

The iPad offers the ability to be more productive, this means you can run OpticalTool beside oher iPad apps that you use the most

Welcome. I specialize only in MASERATI BITURBO parts, the worlds first twin turbo production car. I handle all models of the De Tomaso era twin turbo cars from the first carbureted Coupe to the 3200GT. I've been in the Italian car business since 1980 and Maserati is my passion, my hobby and my profession. I appreciate your business. Thank you, Lenny Celiberti. lenny@auto-italia.com

OpticalTool is an easy app to use and you can choose to take a deeper dive into the information or decide to just use the results of the calculation

View prism amounts per eye and total prism.  See the lenses drawn to gain a better understanding of the effects of cancelling anc compoinding prism

Lens Analysis dives deeper in to each portion of the lens.  For example, weight, lens index when referenced from the Helium d and Mercury e line, height of the ray on the front surface and back surface, and much more

Evaluate the trans chromatic aberration for each material with different powers, base curves, thickness, and vertex distances.

Evaluate the maximum plus and minus that can be created for different center of rotation, material, and thickness values.  Evaluate the best base curve to create a point focal lens for a given power.

Chromatic Aberration Analysis gives a break down of how much trans chromatic aberration(TCA) you will encounter for aeach material at a given viewing angle

Analyze the best curve by reducing tangential and sagittal errors at the desired viewing angle.  See the outcome of a Percival, Point Focal, Minimal T, and RMS designed lens.

Tscherning Ellipse Analysis will show the maximum and minimum power that can be produced for a point focal lens.  You will also be able to evaluate a power to see what curve Wallaston or OStwalt would recommend
