    LED, laser, or other PWM control using Triggerscope

    It appears that more and more people want to use PWM control for illumination devices from Micro-Manager and other imaging software. PWM may be used for any number of applications, from high speed pulsing of an LED, or a laser, in order to reduce phototoxicity or just to control brightness, or to drive a DC…

  • How TIRF works on a Microscope

    TIRF is a widely used tool for effectively creating a super resolution instrument out of a standard widefield microscope. The cool part of TIRF is that it bypasses the limits of axial resolution on the scope not by altering the optics per-se, but by altering what gets excited. In a normal widefield fluorescent microscope, photons…
