Optical Calculator for Windows

This windows calculator is for Optical and Imaging calculations. It has a wide range of functions to support Astrophotography for film and CCD/CMOS imagers and the means to project the image onto the imaging device whether telescope or various camera configurations including lens extensions for cameras.


To better understand many of the functions I highly recommend this book. Many of the film and optics formulas are out it. I emailed him and discussed the calculator with him. He has been a great sport. I just sent Michael a copy for evaluation. See the reference section for all other reference material used for this effort.
