    FIGURE 1. Multicolor switched excitation and emission light paths in a fluorescence microscope differ according to configuration: Pinkel uses fixed multiband dichroic and multiband emission filters (a), Sedat uses a fixed multiband dichroic filter and a high-speed emission filter wheel (b), and Incite uses a high-speed simultaneous dichroic and emission filter switcher (c).
    High-speed filter switching provides improvements equal to doubling or quadrupling of camera quantum efficiency, with reduced risk of specimen phototoxicity.

    FIGURE 1. A point source of light in the focal plane gets imaged by the microscope objective as an airy disc surrounded by a concentric ring pattern resulting from diffraction (a); when projected in three dimensions, these airy patterns (top panels) comprise PSF (lower panels; b).12, 13 The width and depth of these PSFs dictate maximize x-, y-, and z-resolution, respectively, with higher NA lenses generating smaller airy patterns and PSFs, and thus greater resolution (c).
    Ensuring that data generated by advanced imaging methods faithfully represent the biology being studied requires an understanding of key considerations.

    A cellular sample imaged using an Olympus microscope equipped with a Spectra-X LED light engine from Lumencor and Semrock's LED-DA/FI/TR/Cy5-4X-A filter set.
    LED light engines are becoming increasingly popular for fluorescence microscopy, but standard filter sets—including those packaged with the sources—typically limit their performance...

    FIGURE 1. Typical optical shutter designs include rotor drive shutters (a), flag shutters (b), stepper shutters (c), and solenoid shutters (d).
    The design of OEM products for widely different optical applications benefits from collaboration and understanding shutter options.
