This is a small GUI for interactively modelling simple lens arrangements. Collimated and diverging rays are propagated through the lens system, where thin lenses are assumed throughout. If an real image is formed, its position and magnification are noted. An arbitrary number of lenses are supported, and may be added or removed interactively.
Click and drag to change lens focal lengths and positions.
Click the upper labels to manually alter distances, click the lower labels to manually alter focal lengths.

Is it possible /Can you add an option to specific the width of the input collumated beam?
Great. Thank you.
The off-screen issue should be fixed now!
Hi. Looks like a great app but I can't get it to run on my version of Matlab 2016b. TOnly the bottom half of the lenslab startup window appears at the top of my screen and can't be accessed. Any idea how I can rectify this? Thanks
Fixed hard figure size, and Matlab version checking
Fixed plotting bug with 2016b
Added clickable labels.
Added distance display
Removed bug where all lenses could be deleted.
