Several people have the program running and have asked for an example
data input. To show imaging by a biconvex lens of f = 10 (arbitrary
units) of an object plane at 2f (paraxial image also at 2f):
In the first screen ("Configuration") enter the numbers:
First row of "boxes": 1 20 10 8
Second row : 1.5 2 -10 8
Third row : 1 30 leave all other "boxes"
blank, then
click on "ADD RAY(S)" and enter, in the new screen, the numbers:
In the Row "RAY HEIGHT": 0 1 -1 2 -2
In the Row "RAY ANGLE": 0 1 -1 2 -2
Choose "degrees"
Enter a "VERTICAL MAGNIFICATION" of 4
Click "OK"
Click "HIDE CONTROLS" for a clear view (click anywhere to restore
controls)
The "Configuration" entries specify the index of refraction, length, and
terminating interface of three segments:
1.) 20 cm of n=1 (air), terminated by an R = +10 cm interface whose
vertical aperture is 8cm
2.) 2 cm of n=1.5 (glass), terminated by an R -10 cm interface whose
vertical aperture is 8cm
3.) 30 cm of n =1 (air).
(Read the blurb on the "Configuration" screen for more details.)
You may go back and forth among the screens (and change data) by using
the "drop down" VIEW menu.
To those who have asked for a Win3.1 version: Be patient, it is on the
way!
