While trying to figure out spherical aberration in lenses i wanted to see how rays exactly travel through lens
While trying to figure out spherical aberration in lenses i wanted to see how rays exactly travel through lens. I wanted to make free form lenses to try to experiment with focus. I made this app to help myself first. I publish it on playstore to let other also do experiments.Ads:Full Screen ads are shown.InfoThis is optics app to dynamically create complex lenses and test how refraction happens.NOTE(s):- Freeform lenses don't have a fixed focus since surface cannot be easily described mathematic
ally. Please don't expect focal length support!.- In reality there is no fixed focal length of an optical object. Only highest dense focus is considered as focal length. This can easily be tested by creating a convex lens and increasing rays to 100+.- This app is mostly suitable for research or innovative purposes. Can be very helpful in teaching optics.- Red rays are inside medium. Green rays are result rays coming out from medium. Yellow rays are TIR (Total Internal Reflection) rays.Features- As the app name says it allows free forms of lenses. Just paint lenses like an artist.- Supports standard lenses i.e. concave & convex lenses with editing option.- Non freeform lenses are created using bezier curves.Limitations:App has some rules not knowing which can cause incorrect optics or loss of data.- Rays start from left and reaches right end. No other direction is supported.- Lenses when selected show rectangular bound. Bounds of lenses should NEVER overlap as it leads to bad optics.- Currently nothing can be saved for reload. Always save result as image for reference. Active work loss due to app going background can happen.- UNDO REDO is not available.Quick Help:- Set total rays using Rays button.- Create lens using + button. - button to delete lens.- Double tap on a lens to enter edit mode.- EDIT MODE: Use Move button for movements.- EDIT MODE: Use X, Y buttons to enable disable movement along respective AXIS.- EDIT MODE: Use Edit to change shape of bezier lenses.- Export image of optical setup.More help is here:http://www.gamesgreh.blogspot.com/2019/01/freeform-optics-android-app-help.htmlDISCLAIMER:This app doesn't guarantee to achieve optics of real laboratory. Focuses on making small lenses and combinations to make foundation of bigger work.
