Nikon A1 CLSM Configured with TIRF and STORM

The Nikon A1 Laser Scanning Confocal Microscope is configured on a Nikon Ti automated inverted microscope platform with an XY automated stage and provides up to 6 lines of laser excitation.  Laser excitation includes the 405nm, 445nm, 488nm, 514nm, 561nm and 647nm diode laser lines. A hybrid confocal scan head provides both a galvano scanner for high-resolution imaging and a high-speed resonance scanner for live cell imaging.  Confocal fluorescence and/or reflection are detected through a single, variable pinhole aperture and are recorded using two standard photomultiplier (PMT) detectors and two high-sensitivity Gallium Arsenide Phosphide (GaAsP) PMT detectors.  An independent PMT detector permits collection of brightfield, polarized light, and DIC contrast images.  A 32-channel spectral detector with spectral unmixing software is available for separation of overlapping fluorescence emission spectra and/or background autofluorescence.  The system is configured with a fully automated XY stage that may be used for automated acquisition of high-resolution large area scans.

The Nikon A1 inverted microscope system is also configured with optics and software for Total Internal Reflection Fluorescence (TIRF) microscopy and 2D/3D super resolution STORM imaging.  For these specialized applications, the system is configured with a high-sensitivity Andor iXon DU897 512×512 (16 micrometer pixel) EMCCD camera and a 100x Apo TIRF objective (NA 1.49).  A 405/488/561/647 quadruple pass filter cube and a 445/514/561/ triple pass filter cube are available to accommodate a wide range of fluorochromes for these applications.Nikon_R WebNikon A1 CLSM
