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).

Fluorescence Imaging/Microscopy: Improving fluorescence signal in time-sensitive experiments

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).

FIGURE 1. Typical optical shutter designs include rotor drive shutters (a), flag shutters (b), stepper shutters (c), and solenoid shutters (d).

Optical Components: Shutter types vary to meet application needs

The design of OEM products for widely different optical applications benefits from collaboration and understanding shutter options.

Optomechanics provides many mounting choices

Choosing the optimum mount for an application requires an understanding of the basics of optical alignment and mount performance.
