[OpenSPIM] transmitted light

[Feinstein, Timothy N]

Hello all,

Has anyone found a convenient solution for transmitted light illumination that can be controlled Micro-Manager? On the one hand you can use a handheld flashlight (torch), which works but is not something you can program.  On the other hand you have collimated light sources from e.g. Thorlabs.  Those do the job but they seem excessively powerful and expensive for what should be a pretty basic task.  I went searching for cheap USB-powered lamps that can be controlled through a software interface rather than a physical switch but those seem strangely hard to find.  As it stands I might put a DIY LED bulb in a cheap 'collimator' like the one below and link it to uManager through an arduino.

Even so I feel like I must have missed a simpler option.  Any thoughts appreciated.

Thanks and all the best,


Tim
