25. Graphical User Interfaces with Tk — Python 3.5.2 documentation

It provides a robust and platform independent windowing toolkit, that is available to Python programmers using the tkinter package, and its extension, the tkinter.tix and the tkinter.ttk modules. The tkinter package is a thin object-oriented layer on top of Tcl/Tk. To use tkinter, you don’t need to write Tcl code, but you will need to consult the Tk documentation, and occasionally the Tcl documentation. tkinter is a set of wrappers that implement the Tk widgets as Python classes. In addition, the internal module _tkinter provides a threadsafe mechanism which allows Python and Tcl to interact. tkinter‘s chief virtues are that it is fast, and that it usually comes bundled with Python.

Setting lens focus. Since this simple thread fit is not purposed for precision focus adjustment, some understanding and improvisation is needed to make it work well as such.

setting lens focus

I measure the stock lens as having a metric thread, namely M6x0.35. So a fraction of a turn is only a few tenths of a mm at most. There is a lot of "allowance" in these threads relative to tenths of a mm, so you need either some preload force against the lens into the rearward direction of the threads, or some gap filler like PTFE tape. Otherwise the lens will rattle back and forth and throw off your focus adjustment. ("Allowance" in threads is the term for the positive gap between the largest allowed male thread and smallest allowed female thread, in the range of sizes permitted for a given thread standard, so that threads do not interfere.)
